  1. ThePhysicist

    Texas sharks

    From the album: Eagle Ford Group

    A handful of Cretaceous sharks (and fish vert) from an outing in the Kamp Ranch Limestone. Not particularly plentiful, but great preservation.
  2. ThePhysicist

    Cretoxyrhina in situ

    From the album: Eagle Ford Group

    A razor-sharp Cretoxyrhina in plain sight.
  3. ThePhysicist

    Squalicorax in situ

    From the album: Eagle Ford Group

    A perfect Squalicorax, just lyin' there.
  4. ThePhysicist

    Exploded inoceramid

    From the album: Eagle Ford Group

    The remains of a large bivalve, which are quite common in the limestone.
  5. ThePhysicist

    Hash plates

    From the album: Eagle Ford Group

    In the laminated limestone occurred thin lenses of concentrated fossils. These don't look like much, but they're riddled with fish bones and other microfossils. I will likely sacrifice a couple of pieces to study the microfossil content.
  6. ThePhysicist

    Digested Ptychodus?

    From the album: Eagle Ford Group

    This Ptychodus is missing its root and enamel, it's possible it was swallowed and digested by the animal?

  9. When I caught wind of @jnoun11's traveling exhibit coming to Canada, British Columbia of all places, I made sure to book it down to the Vancouver Aquarium immediately! It was the most incredible display of Moroccan fossils I have ever seen and far greater than any permanent museum galleries! Of course I spent most of the time at the mosasaur section, finally getting the chance to see the marine reptiles I work on fully reconstructed in all their glory! The best part was seeing the species of mosasaur @pachy-pleuro-whatnot-odon @Praefectus and I named on display for the whole world! Such a great feeling! The skull of Hainosaurus boubker stood proud along side Thalassotitan atrox and the skeletons of Mosasaurus beaugei, Halisaurus arambourgi and Zarafasaura oceanis (plus some turtles). The murals in the back illustrated the diverse community of the phosphates in an active, warm sea environment which made you feel like you were right there swimming with them! The info boards were great and very informative with a fun "Monster Level" gimmick to show how fierce these predators where in their environments and times! Unfortunately Hain and Thalass were still under their pre-2022 names of Tylosaurus and Prognathodon anceps (plus using their smaller size estimates) which hopefully one day will be updated. I purchased a seasons pass just to revisit this display several times this summer while it is still around! Here are some photos of the mosasaur section (plus Spinosaurus) I took with my good camera!
  10. In the last couple of months my son and I have purchased some unprepped Lebanese fossil fishy's. There are four known species of guitarfish from the Lebanese provinces of Hakel and Hajula. Rhinobatos maronita is one of these; this species was fist described in 1866 by Pictet and Humbert. Some purty dang cool stuff but the guy we are buying from does not know how to wrap and send fossils over seas! Our last shipment came in many pieces! Not good. My son is working on him to make it right? Aside from that Im going to do what I can to fix things. First up is one side of what I think is a Guitar Fish, Rhinobatus? My son purchased this and this is the 'not so good side' with the other side being in better shape. Every so often I will be back and make more post of these realy neato fossil fishy's. @oilshale I dont know much about the types/specimens of these fish from Lebanon so if anyone wants to chime in and correct me, I would greatly appreciate it. Thank you RB The back half of this slap used to be in one piece!!!
  11. Today, I went trekking with my father in a fossil site located exactly at the Jurassic-Cretaceous transition. We left at 6 AM and arrived at the site at 8 AM. We were at an approximate altitude of 2000 meters, and the temperature was surprisingly pleasant despite it being mid-autumn here. We spent about 3 hours climbing and exploring to see what we could find. The camera on my phone doesn't do justice to the majesty and beauty of the views in the area. I love going to this place; it brings me peace. I look forward to hearing your thoughts and wish you all the best!
  12. Hi All, I previously had a thread running with all of my Winter finds in Monmouth Co., NJ. It's one of the more common areas I go to hunt, so thought I would start a Spring/Summer thread. My last hunt was on 4/27. Myself and another collector I've been speaking with on Instagram decided to check out a Cretaceous spot we've both been to seperately. Before heading there, I went out early and visited another Cretaceous spot, Big Brook. Haven't been here since last September. Had a good hunt, which included a nicely preserved Belemnite, a couple Gastropod Steinkerns and a decent sized A. kopingensis tooth.

    A Fossil A Day.....

    A Fossil A Day....keeps the blues away! Or something like that... I started an Instragram account (jamielynnfossilquest) and am posting a fossil a day, so I figured I should do that on here, to REAL fossil enthusiasts! I'm a few days behind, so I will start out with a few more than one a day but then it will settle down to One Fossil (but I will admit, I'll probably miss a few days, but I'll double up or whatever.) I'll start with Texas Pennsylvanian era, but will branch out to other locations and time periods, so expect a little of everything! So enjoy A Fossil A Day! Texas Pennsylvanian Fossils: Nautiloid Agathiceras ciscoense Brachiopod Neochonetes acanthophorus Trilobite Ditomopyge sp. Gastropod Straparollus sp. Bivalve Astartella vera Cephalopod Brachycycloceras sp, Brachiopod Cleiothyridina orbicularis
  14. Hey folks, Poking through some finds from my latest set of trips and i'd appreciate some help IDing some mysteries from either the NJ Cretaceous or MD Miocene Cretaceous, Monmouth Co., NJ 0 - Originally, I thought this vertebra to be a very beat up shark, however I also think it can be sawfish Ischyrhiza mira given the lack of distinct cartilage attachment points we see in sharks. Miocene, Calvert Co., Maryland 1 - No guesses on this one. 2 - This could be a mylobatidae dermal denticle? 3 - Clueless on this one too, aside from a vertebra of sorts?
  15. I have read through Arambourg's "Vertebres fossiles des phosphates de l'Afrique du Nord" in an attempt to gauge what species of the genera Cretalamna are present in the Ouled Abdoun Basin, with the help of sharkreferences.com. According to these two sources, 2 species are present in the phosphates: Lamna appendiculata - Cretalamna appendiculata Lamna biauriculata maroccana - Cretalamna nigeriana However, on elasmo.com, Lamna biauriculata maroccana is stated to be synonymous with Cretalamna maroccana, a species not listed whatsoever on sharkreferences.com. The L. biauriculata maroccana teeth in Arambourg appear to be immensely similar to those labelled as C. maroccana on elasmo.com, which has led me to believe that C. nigeriana and maroccana are synonymous, which leads me to the question of which is valid, of which I am not sure. Thanks in advance for any guidance Othniel
  16. T. rex fossil found by children in North Dakota to be displayed in Denver museum, KTVQ News, Billings , montana Museum to Display Young T. Rex Fossil Found by Dad and Sons Inside Edition, June 10, 2024 Hiking family discovers rare T. rex fossil By Jacopo Prisco, CNN, June 7, 2024 Yours, Paul H.
  17. Given such lovely weather this morning, we decided to head out on a quick day trip to our favorite locale for creek hunting in NJ. Seemingly a lot of other people had the same idea and the stream was full of many, many more people than I usually see. Most wanted to enjoy the quiet tranquility though occasionally I would hear an excited yell from quite a long distance away. My usual methods of scanning the gravel bars bore little fruit with most being picked clean already so we opted to dig in and sift for the day, bringing a great haul up as we dug down into the creek bed. Finds going from left to right as pictured: - Pulling up the shark vert was quite a treat! At about 1" in diameter and a little beaten up, it is by far the largest I've found in the NJ Cretaceous and at this locality. Also pictured are two incomplete verts, much more representative of the usual size found - Next up we brought in some nice goblin & crow shark teeth. Not the biggest, but quite happy with the stunning coloring - Likely modern, but a funny find nonetheless. Likely a bison or cow tooth - Finally, a misc pile of teeth, fragment of a ghost shrimp claw, fish jaw and a small piece of petrified wood
  18. After an unusually long, blissful spring, summer has arrived here in Texas. School is out, and my schedule is open, free from the burden of classes. Despite the freedom, my time has been getting filled. Working on a mosasaur paper, prospecting new sites, social commitments and a fun day job are forming good memories, and more are coming (I'll get to that). First though, my excursions from a week ago --------------------------------------------------------------------------------------------------------------------------------------------------------- For the past few months, my finds have been few. Split between the duties of the semester, I haven't been getting out much, and when I have been going out, I've been looking hard for new sites, rather than returning to old honey holes. Despite my intrepid searches, no dazzling new sites have turned up, but that's the game and this kind of work is what it takes to play it. So, starving to get my hands on some fossiliferous rock, I returned to a tried a true spot that sometimes yields cool finds. It's a beautiful, tiny stream that's surprisingly accessible if one is willing to get wet and bushwhack. In its course, it reveals the blue-gray upper eagle ford formation, a Turonian layer famous for oil and exceptional marine vertebrate fossils. Above it lies the Austin chalk formation, with it's lower-most member (the Atco member) coming in at a Coniacian age and contacting the Eagle Ford. Both these layers are rich in fossils but contain different faunal assemblages, making a cool, visible case study for how marine ecosystems evolve. Some species of Ptychodus like P. anonymous can be found in the Eagle Ford, but move a few inches up into the austin chalk and they vanish. Other species like P. whipplei and P. mortoni abruptly appear in Coniacian Austin chalk layer, but do not occur in the slightly older Eagle Ford layer. The same seems to happen with Mosasaurs like Russellosaurus, so far only ever found in the Eagle Ford - an early precursor to the diverse, strongly marine adapted plioplatecarpine mosasaurs that would succeed it. My first find as I moved up the trickling waters was a partial ammonite. I was not yet in fossiliferous territory, but this wayward cretaceous traveler told me moving upstream was the right call. After a short endurance run, I made it to a bend in the stream where it constricts to no more than a foot or so across. Squatting in the deep gully, with walled banks just a few feet away on either side, I noticed a brown, shelly conglomerate protruding form the gravel. This was an escapee from one of the few highly fossiliferous lenses in the upper eagle ford, and I knew to spend some time with it. Picking it apart, I was not disappointed. First to show was perhaps one of the most prolific sharks in the Turonian seas, Squalicorax falcatus. Invigorated and impressed by the beautiful coloration, I kept on, eyeing every piece of the conglomerate as I knocked away. Close by came another beacon of the texas Turonian: the small, charismatic Ptychodus anonymous. Every Ptychodus tooth I find probably adds weeks to my life. Halfway through the dinner plate sized conglomerate, I could have moved on and been happy. However, still to come were the true gems of the Turonain Ptychodus species and I'm glad I stayed. If you look in the right places, an astute observer may notice a tiny lens, representing just a blip in geologic time, where the typical Ptychodus anonymous teeth of the formation take an odd turn in their morphology, hosting wrinkles that somewhat converge at the apex, almost like what's seen in the later Ptychodus mortoni. This unusual morphology is an undescribed species, and the work being done on it has been threatening to release for ages. At least it means that this species is getting attention . So, trucking on, I was met with a beautiful sight: Here it was: Species X, in crisp detail. The soft matrix made the grand reveal an easy task. With three flawless teeth from a single rock, I was ready to move on and find the origin of this tumbler. First though, the final portion demanded attention. My jaw fell down after I dropped the next hammer blow: For species X, this is a large tooth, and I recognized it immediately as one of the best Ptychodus teeth I've ever found. My pick and a few carefully directed hammer blows made quick work of the surrounding matrix. This is one of those weirdo teeth that flirts with the boundary of species X and P. anonymous. I think it could fall either way. Stunning. As I moved on, I enjoyed the scenery and the extant fauna. It's easy to look by the extant creatures we share our creeks with, but it's good to remember that fossils are cool because they were alive once. We can all do well to tip our hat to our creek side neighbors. Spiny softshell turtle Diamondback water snake (Nerodia rhombifer) As I left the creek, I found a reminder of my previous point, with a creature who once straddled the position of extant and extinct that never made a comeback to its original glory. Laying like a pearly beacon in the gravel was a large Bison tooth, locally extinct for at least 150 years. And so concluded a fossiliferous trip. With my collection tub heavy, I was now prepared to return to a challenging goal I've failed at twice before. ------------------------------------------------------------------------------------------ Though a hunter from the start (and in my heart, I suspect I always will be), my goals have been shifting academically since I first noticed my interest in fossils 3 or so years ago. In particular, I've been assisting in mosasaur research, on the specimen my brother and I found. I hope this will be the first of many that I will work on. But I digress... One of the richest fossil assemblages of mosasaurs in the world is in the Maastrichtian of morocco. There are a few reasons: 1) Coastal Africa was a source of up-welling, shallow waters, and abundant food. 2) The chemical environment of the moroccan phosphates was conducive to preserving fossils 3) Mosasaurs were very diverse during the Maastrichtian, arriving on fantastical dentitions, unique body plans, and varied (even segregated) feeding strategies to survive. This is thought to be niche partitioning, where species adapt very specific methods of life to avoid competition with other species like them. The third point implies that mosasaurs everywhere should be diverse during the Maastrichtian. Due to their sheer success at the end of the cretaceous, niche partitioning must have been inevitable, driving high rates of speciation. I don't think that Maastrichtian morocco was all that unique during that time. There is a selection bias towards fossils being discovered there due to the commercial digging and mining activity, but as far as paleo environments, other shallow seas likely rivaled morocco in diversity. The most famous shallow cretaceous sea, at least in my corner of the world, is the western interior seaway, bisecting the north american continent. During the Maastrichtian, it was a shadow of its former self, but nonetheless a substantial body that drowned much of Texas. Yet, despite that, Texas has a very poor record of Maastrichtian mosasaurs. One reason, perhaps, is the tsunami that the cretacoeus ending Chicxulub meteor generated. Much of the upper Maastrichtian marine strata in texas is a tumbled mess due to the apocalyptic force of the wave that crushed Texas that spring day 66 million years ago. The tsunami ripped up millions of years of strata in some places, now visible as tsunamite deposits with Maastrichtian debris branching up into the Danian deposits. However, some spots survived, with the K-Pg line visible in some places in Texas. Elsewhere, early maastrichtian strata stayed in tact, spared by its depth in the strata at the time. My goal was to find maastrichtian marine strata and prospect for mosasaur material. Because of how poor the maastrichtian record is here, coupled with the high degree of endemism in maastrichtian mosasaurs, I suspect that the Texas maastrichtian hides many undescribed species. The problem is that Texas maastrichtian outcrops are uncommon, and if you're lucky enough to find one, they chew you up and spit you out. Worse, they're poorly sorted on geologic maps, which often just display groups instead of formations. Some formations are better than others, so using a map means you have to do the leg work and filter out the formations you weren't looking for in person, one by one. After several challenging excursions in barren rock with nothing to show but a sack of woe, I'm not surprised Texas has such a poor record of maastrichtian vertebrates. But, this is the game Two excursions this year into my best maastrichtian spot have left me with large oysters (Exogyra costata) but nothing else. However, invigorated by yesterday's Turonian success, I set out with maastrichtian mosasaurs on my mind. Site 1: A partial success. After long last and two other failed attempts, I finally found an outcrop of the upper taylor marl (which lies on top of the Pecan gap formation, which itself lies over the lower taylor marl (AKA the Ozan formation)). Though not maastrichtian, this middle campanian formation is a tad younger than the well explored Ozan, and could promise different animals. I found it lithologically indistinguishable from the Ozan formation, but I'm sure a geologist could separate them on sight. Though some research promises that in it's upper reaches, bountiful, spectacular ammonites could be seen, I saw nothing. In fact, the only difference I could make of it from the Ozan is that it has fewer fossils. I must come back! Site 2, that same afternoon: My old nemesis, a beautiful maastrichtian cliff of unknown geologic affinities. My suspicion lies with a Kemp clay ID, but I'm not too sure. Two times this enormous, searing outcrop has turned me away, burned and empty handed. Due to the sheer extent of this outcrop, I suspect my best chance for maastrichtian mosasaur material lies here, despite the unforgiving rocks. As I began, I crossed the creek below to the flat opposing bank, in case it gave me views of more outcrops down stream. A small gar, perhaps 3 feet or so, meandered through the murky water in front of me as I crossed, while peaceful oak/elm savanna rose from the banks before me. I trod though bushels of grass and vines, no different than usual, when an explosive, fiery pain scorched my calf. Chewing my tongue and resisting the urge to immediately claw my leg, I made haste back to the water to submerge myself. I have the benefit of what seems to be a partial immunity to poison ivy. I tread through jungles of it, even seeking out outcrops choked in it as my advantage because it deters other hunters. Outbreaks are rare and small for me, often only coming days after my excursions. Whatever plant did this to me was of evil crop, and I have no idea the culprit. The cool water did little, and despite my leg being wet and sunscreen smeared, the oil/spines took strong effect. It took great power of will not to touch the agitation for the next 10 minutes, but then, suddenly as it came, the sensation disappeared and my leg was fine again, though a bit sensitive. Very unusual experience. For my sufferings though, I did not come away empty handed. Early on, as I worked a tumbled boulder, I paused a hammer blow to see this where it would've landed: Heart attack averted, I plucked it from it's resting position, and in my hand found the broken apex of a mosasaur tooth - my first from maastrichtian strata. Though diminutive enough to consider fish, the ornamented enamel, notable thinness of the enamel, and bicarinate nature point me to mosasaur. What's more, the ridges seem unusually strong for a tooth apex. Not something I expected, and so this supports my idea that there is a hidden diversity of unseen mosasaurs from Texas maastrichtian waters. Not the complete, articulated skeleton every hunter fantasizes about, but a tantalizing clue that I'm in the right place. Though sometimes punishing, I can't wait to return to this place
  19. This week and next are prime mid year astrophotography new moon nights for astrophotography. May, June and July are the best months in the northern hemisphere with June's New Moon being one of the best and longest Milky Way shows hands down. What does astrophotography have to do with fossil hunting? Not a whole lot really, but I happen to enjoy both endeavors and have found that I can combine the two together. Fossils in the daytime, stars at night. Like having that proverbial cake and eating it , too. So it just happens that on the way to The Last Chance Desert, Utah where I can enjoy a Bortle Class 1 dark sky there are a thousands of square miles of treeless desert locations with fossils to find on BLM land from just about anyone's favorite period and formation. I like ammonites since vertebrate fossils are off the collecting table on Federal lands. Here's the terrain where I stopped for a short session. There's literally miles in this image of fossil rich exposed layers to explore. I still had 50 or so miles to drive deeper into the desert so my hiking session was going to be determined by the soon setting sun. Less than an hour. I'm parked on a gravel dirt road and changed shoes into my rugged hiking boots to protect me from Opuntia polyacantha cactus spines. These are a species of prickly pear with "many thorns". The spines are on average 3 inches or nearly 8 cm long which will pierce soft shoes and skin easily. In the above image, I had just finished tying my boots, scanned the area and decided on a counterclockwise zigzag loop downhill following first the ridges and then a second undulating loop following closer in the eroded ditches. I could already see concretions exposed on the surface and knew I would find evidence of previous visitors having hunted this same location. So with some hope, enthusiasm and experience I was going to make the most of my short session. The concretions containing fossils are normally flush with the surface of the dirt and sometimes subtly a small rounded area would be exposed. Those in the foreground were previously dug, inspected, flipped over and often cracked open with a hammer. Here's how the first 15 minutes of hiking went. Once and a while the footprints of the previous hunters were visible and more so when I encountered an excavated concretion. My circuit down the slope shows the shadows were getting longer and my hunting time was getting shorter. This concretion was promising but whoever excavated it left it intact, as did I since no ammonite tubercles or whorls were protruding or revealing any recognizable fossil shapes. But the overall shape does suggest a big ole ammonite just a few centimeters under the hard skin surface of the concretion. But that's okay to leave it. It might still be there next time I stop. Keep going! ...and another dig site. And more... ...and some more... ...and guess what?...more of the same... Without trees, cliffs, obstacles of any kind, a lot of terrain can be covered quickly and easily if one watches their step while also looking at everything. I'm now at the bottom of my winding loop and heading back uphill towards my vehicle. I run into a big batch of excavated concretions and look them over carefully in case something was missed. Some busy beavers have been through here. Another piece of evidence I was searching for was a hole without a concretion near it, suggesting that something worth collecting was found. Not many such spots and in the above image I looked very carefully for the hole without the concretion. As I ascended the slope you can see the line of concretions just like a trail of bread crumbs. So I keep following the trail with zigs and zags left and right as I head towards my car. And then I met this guy who seemed to not be as startled as all the other desert grasshoppers which launched and flew off into the sunset every few steps. It even allowed a couple of posed pictures...The thought came to mind from the TV series way back in mid 1970's Kung Fu ...something to the effect of "be patient grasshopper, like I am" . and I held my phone much closer....yet it didn't blink ( no eyelids) nor fly away. Thanks, Hopper! So I walked a little slower and looked a little closer...hmmm...this one got split open. Someone was more serious than just digging and flipping it over. The concretions do usually have a distinct top and bottom. The top might be tan/khaki colored and the bottom would be light beige on the white side due to a calcite or other mineral coating. And this one....sadly was indeed an ammonite. I picked up a few nearby pieces to see if they fit. The previous excavators my have tapped it just a wee bit too hard. It was coming apart like a 3D puzzle and no picture to compare with. I left it. The last ditch on my right would lead me up the hill to my car. But wait, there's a few more excavated concretions to check. Nope....nothing to see here, folks. Into the ditch! This view is the ditch I searched but from a rear view looking back at it. Near to the greenest area in the pic is where I walked into an area I had yet to search. Not ten feet later...I spied a concretion, this one in particular, that may have eroded out from rain runoff - AFTER - the previous hunters had scoured this field. I stared at it and thought, well, why not, it's just sitting there and had not been dug out or flipped recently. It was embedded well and this pic is actually taken after I flipped it and put it back close to its original position. I wasn't expecting to find anything anyway. Surprise! What I shock! I had hiked almost the entire loop and was headed back to the car just 20 minutes later and Voila! ....the grasshopper was right...be patient and persistent. Immediately after the shock of discovery was the reality of the weight of this big boy ammonite. HEAVY! and a centipede was insistent on keeping it for itself. Zoom in for the centipede...it soon crawled away under another rock. My initial ID for this specimen is Prionocyclus macombi...why? because they are found in the Juana Lopez formation. It could also be Prionocyclus hyatti. How heavy is it? HEAVY...Flipping it was somewhat easy, a little adrenaline and enthusiasm goes a long way sometimes, but I knew I couldn't carry it up the hill to my car about a hundred twenty meters away. The terrain and gravity were not my friends at the moment. I hefted it up and cradled it against my chest and staggered out of the ditch and walked with it about 5 meters. THUD! I heaved it forward onto some soft, rock free, dirt. What a beast. I thought for sure it weighed over 50 pounds/ 23 kg because I can easily lift and carry that much. Just minutes ago, I grabbed the scale and carried it out to garage to weigh it proper. Drum roll.....first I weigh myself...175#/79kg fully clothed with shoes...check. Now let's lift the concretion and step onto the scale with it. Oh my!...284#/129kg...combined weight. Which brings the concretion to 109#/49kg. No wonder it felt HEAVY....it is HEAVY...at least it is for a scrawny old man. Yep...I'm a happy camper, today. Oh...and then after loading it into the front floor of my car, I headed straight south for a night under the stars. On the way I had the sunset on my right and the Belt of Venus on my left. These pics are color enhanced quite a bit...obviously, but I like 'em like that sometimes. Steve If you don't know the Belt of Venus - it happens at dawn and dusk on the opposite horizon of the sun. The pink is from the sun's last or first rays and the blue is the Earth's shadow. It lasts 10-15 minutes and I know driving fast and taking pics is not the best way to enjoy it...but I did.

    Texas Cretaceous... Crocodile?

    After doing some internet research I am tentatively thinking these might be crocodile teeth rather than fish.....I can't seem to find any examples of Cretaceous fish that these might fit. But looking at the croc teeth, I see some similarities. Both of these were found at the same site in Central Texas, Austin Chalk formation. They are 1/4 inch. Any thoughts on these ? 1. 2.
  21. An old couple from our rockhound club had a sale last weekend. They could not recall many specifics about the fossils they had except for the ones I already knew, so I was reluctant to take them, but they pretty much foisted them on me, so here they are. I don't know if I should list these in separate topics, but this is easier... One of the more interesting items was this fat, squashed ammonite, which looks Jurassic and reminds me of one I got elsewhere a while ago that is probably Iniskinites sp. from probably a Jurassic site up near Smithers, BC, but I'm not sure of that info and I'm not sure this would be from the same place, as there is more iron oxide on this one an it is quite heavy too, so it must be some high in iron (ironstone).

    Turtle claw or crocodile claw?

    I bought this claw pretty recently and it said it was a crocodile claw but when I looked at other claw it was identical or almost identical to turtle claws the deller also was selling. I'm unsure if this really is a crocodile claw and if it by mistake was marked as a crocodile claw. Here are some images:
  23. Hello and happy New Year! I have visited this region a couple of times, earliest being around 2000 and last time just a few days before the NY Eve. My first visit was limited in Chaeronea, in order to visit the Marble Lion that was erected in honour of the fallen soldiers of Theba, who fought against Philip, father of Alexander the Great. The battle took place in 338BC, technically was a civil war between the city state of Athens and Macedonia. (The Lion) Following the road South of the lion, I found my first rudist on a dirt road. All I can say is that the site is Santonian. Years later, December of 2019 or 2nd of January 2020, I visited the mountain of Ptoo at the locality Marmeika. This is an abandoned nickel mine, more precisely, a pit. Middle Turonian possibly up to Coniacian This is an amazing outcrop for rudist lovers, because you can observe huge colonies in life form. I really regret it I did not take pictures last time.. Moreover, it is the place with the most diversified fauna. I will start with the finds of the first time. Nerinea sp vertical cut and steinker. Very typical find, usually away from the rudist zone. Radiolites sauvagesi, I think. Abundant in the lower greyish limestones. Finds of my last visit. A quite large sponge (Demospongiae?) which is completely silicified. I am not able to narrow down its species. Close-up showing its stracture An amazing Actaeonella sp, which has all of its shell, yet one end missing. My top find I think. The same Actaeonella next to a cross section of another Actaeonella. A nice gastropod that looks like Ampullina sp but did not find a reference. More Nerinea sp One more Nerinea sp as found And after 1h of cleaning. The limestone is very soft and easy to remove. Two interesting rudists. The left one must be Radiolites mamillaris. The one on the right side, no idea! Rudists collected in the area during my last trip to Greece, December 2021. Still in boxes in my car. Aghia Varvara section: The scientific research leads you at a small hill, near a chapel. Although it is described as rich in gastropods, the area has mostly badly preserved specimens and some fractured rudists. The most interesting find from this section, is a matrix free cross section of a rudist, replaced by calcite. It is just a slice. 1.5-2Kms SSW of the section mentioned above, we found another layer of the same formation which gave some nice fossils. Neoptyxis incavata or Neoptyxis symeonidisi, as per the references. Can't tell which one. The gastropod on right side, no idea. One Neoptyxis sp in situ. The layer that was found was tertiary so it must have been redeposited. Rudists are very underrated fossils. However, if exhibited with other species of the Cretaceous sea, will create a very artistic illustration of a reef. Maybe there is someone who might be able to help a little with identification @FranzBernhard Hope you enjoyed! References: Cretaceous Rudists of Boeotia by Thomas Steuber [1999]
