  1. I've collected in the New Jersey brooks for a long time now, and I've found a few pieces of dinosaur material over the years, but I'm interested to know if there are any other public land collecting sites in the US where one can find (and keep!) dinosaur material.
  2. As a freshmen in College, I did a little extra credit report for my geology class about a controversial topic - Tyrannosauroidea diversity in the Southern Hemisphere during the Jurassic-Early Late Cretaceous periods. I was quite surprised at the amount of specimens I found. This diversity likely was the result of an early spread of the early tyrannosaur group Pantyrannosauria into Africa, Eurasia, and North America during the Jurassic and diversified once the land connecting these continents spread out more. Most of these species lived during the Early Cretaceous, though one or two exceptions might have lasted into the Early Late Cretaceous. I've created a list of known of the species and specimens which I would like to share on the forum (let me if there are any examples I'm missing or should add): South America Santanaraptor (Romualdo Member of the Santana Formation) (Early Albian, Cretaceous period 112.6-109.0 million years ago) Specimen: MN 4802-V (partial skeleton) http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&collection_no=67712 Tyrannosauroidea indet.

  4. Hello everyone! Here’s another mystery (to me at least) from the Kimmeridgian (?) of Wimereux, North of France. It doesn’t seem to be bone. Is it a shell, plant, crab or something else? Thank you for your help!

    Osmylopsychopsidae non det.

    From Peng et al. 2015, p. 2: "The systematics of Mesozoic psychopsoids is very complicated and confused. This group of Neuroptera includes taxa with broad and multi-veined wings that are currently classified in five families, i.e. Osmylopsychopidae, Brongniartiellidae, Psychopsidae, Kalligrammatidae and Aetheogrammatidae (Makarkin et al. 2013). Kalligrammatidae and Aetheogrammatidae are easily distinguished from other psychopsoids, whereas the Mesozoic members of the three other families (i.e. Osmylopsychopidae, Brongniartiellidae and Psychopsidae) hardly differ from each other.". Determined in Mai 2023 by Dr. Vladimir N. Makarkin, Institute of Biology and Soil Sciences, Far Eastern Branch of the Russian Academy of Sciences, Vladivostok, Russia: "This is a species of Osmylopsychopidae, possibly new."

  7. Notidanodon

    Ichthyosaur tooth

    Hi guys just wanted to see if anyone could identify it past the current label thanks! @pachy-pleuro-whatnot-odon @Praefectus
  8. Dear members of the fossil forum I am contacting you because I need help in identifying an interesting specimen that I am currently preparing. The find is larger than I initially expected and seems to extend over the entire slab. Originally I thought it was the humerus of a pterosaur (Rhamphorhynchus sp.), but on closer examination under a stereomicroscope I noticed strange "nodules" on the surface of the bone. As far as I know, these are atypical for pterosaurs. The further I dissected, the stranger and more confusing the specimen became. I would never have expected to come across the parallel pieces, some of which lie under the bone and have a T-shaped cross-section. It comes from a limestone quarry in Mühlheim and I have been given permission by the owner to take it home for further examination and preparation. However, even he is at a loss as to what this "structure" is. Based on the colouring in the transverse fracture, he suspects that it could be a reptile rather than a fish. After extensive internet research, I have ruled out the possibility that it is a plant, an arthropod or an echinoderm, but I am happy to be corrected. Thank you in advance for your help and I look forward to your comments. Kind regards DrGrant
  9. I have got an ammonite with an old collection, but, where does it come from and whats the name...? I am sure it is a middle european one, france or southern germany. And think I have seen one like this many years ago, but..., forgot the name (might be something like Hecticoceras, but it does not fit perfect). Might be someone can support with the determination, this would really help a lot. thanks!
  10. The previous thread posted was filling up and I needed a short break. The Castle Dale Museum was a nice treat as this was my first visit any of the towns along highway 10 which runs north and south on the west side of a huge Morrison Formation where the Cleveland-Lloyd dino quarry is located and endless locations of Cretaceous, Triassic and Jurassic fossils are found. These fossil locations are mostly treeless as you see in my photos so that surface finds are only a matter of walking through the formations. People think there are "secret spots" to find the best hunting grounds for big and small game, rocks, minerals, rare plants, fossils, etc. Nope...nearly if not all land has been walked on by humans. Those who hunt fossils in Utah talk of such places and In my opinion these "secret spots" or " honey holes" are only such in their own minds. Today's tech just using Google Earth mapping will find anything you look for. Crashed airplanes- simple. Morrison formations in Utah deserts...way too easy. Fossil concretions are quite visible from satellites looking down into Utah deserts. Not to poo-poo on the idea myself, people ask me all the time where I caught such a huge fish. I say I caught it in the mouth. They persist and I say in the water. They get the point and we have a laugh. Then I will share a location with them. They ask what bait. I say 'bread', they say, 'Bread?', I say bread, they repeat, 'bread?', I say yes, like a sandwich. Again the light bulb comes on, we laugh and I tell them that every source of Utah waters has big fish like this in it and most people feed ducks at those water sources. Fish are under the ducks eating bread, too. This applies to fossil hunting in Utah...where did you find that? In the desert. Between Green River and Salina or Moab and Price or even in Salt Lake City. Then I say fossils are under your feet. However, giving away your favorite spot isn't smart collecting because someone has already been there. But at the moment it can be your "secret spot" and productive site. Utah certainly has been fossil hunted for over a century continuously. Off the soap box, back to the trip which thus far has allotted me 4 hours of sleep in two days. Lets go, Steve! Here's my "secret spot". Thanks to Landsat/Copernicus imagery. The banded Morrison Formation is easily seen from space and the Cretaceous formation is like the pie crust around it. The Jurassic National Monument is also known as the Cleveland-Llyod Quarry. You can google it for more. Keeping the honest folks honest. Once I parked among the other visitors, I checked it and the gal asked if I had a park pass. I showed her mine. She sees the "Senior" diamond shaped emblem on it and says, no, that's not your card, Yes it is, here's my license to go with it. She smiling, no way you're that old. Yepperdo! I get in free and we had a nice, fun , chat about retirement, thinking good thoughts, loving life and making the most of it. The daylight caused many reflections on the glass cases. A bone in a jacket. The most touted Dino next to the Utahraptor, the Allosaurus. Say Cheese! Outdoors is mile and a half trail and the other building covering the 'big pile of dino bones'. This model seemed quite well constructed. Upon exiting, I noticed we were also leaving the Morrison formation. See any concretions? See any now? When I was close to entering the Park site, I noticed a couple getting out of the van with buckets and a pic. Well, methinks there's a blatant clue. Be sure to dial 811 before you dig! Upon driving back out of Morrison formation back onto BLM land and Cretaceous sites, I noticed the same vehicle still there over an hour later. But the couple weren't visible. I turned down the side road, stopped , put on my hat and greeted them. All went well and they welcomed me to join them. I offered to move to another site and they still welcomed the company. I showed them what I had found the day before in another town outskirts and they had not seen trace fossils here before but the guy knew that meant tunnels, burrows, footprints. They actually had bird tracks from that place in the beginning of the other thread with the snow on the summit pass. I found a nice trace fossil right away and gave it to them to get their bearing on what to look for. They were excited and the gal found 4-5 quickly and was very pleased with them. They had been at this location several times and were about to leave but suggested I search the hills and into the washes and ditches. I helped lift a huge concretion into their vehicle and they did the same for me as they left. Bending down to lift their concretion I saw this piece under his foot. I did take a few pics but enthusiasm won out as it always does and the picture taking falls to the wayside. A pic of his find. A pic of mine. ...and more... The Heavy. I'll get the bucket contents sorted ASAP and add those. Gotta apply some generous amounts of CA to some pieces. Steve PS - Oh, I early forgot! While I was at the Nat. Park I was traipsing along with a family, mom, dad and twin boys. The boys talked fossils the whole trip according to the mom. They were from Georgia and were going to the Natural History Museum in Salt Lake the next day before flying out. I said your boys will love it. It's like a 100 of this collection. One boy asked was this a fossil - holding a polished rock. His mom said it's a rock, I said , yes it is, but it could be a fossil gastrolith. A what? the boys exclaimed. Gastro= stomach, lith = rock. A stomach rock. Dinosaurs swallowed rocks to help grind and digest their food, just like birds do. But if you stop by my car on the way out, I'll give you a for real fossil each. I gave them my Birgella sp. gastropod fossils collected the day before. They were happy.
  11. Like the title says... it's a bit on the crammed agenda for only two days. But not if you don't sleep. lol! Old people don't need all that much sleep anyway, so I've found out. Tuesday the 2nd of April I was up in the foothills above Salt Lake City checking out the Anasibirites Bed in the Triassic Thaynes Formation. Wednesday, I'm packing up my camera gear for a session of astrophotography in The Last Chance Desert between Green River and Salina, Utah. Not only is Utah full fossils, it's also renowned for it's beautiful dark skies at night...but only way out in the desert. We have light pollution like anywhere else in the urban environment and just an hour or two we have Bortle Class 1 dark skies. The scale goes from 1 to 9, 9 being like Tokyo and1 being in a desert, ocean or unpopulated, unlit location. Fishing, Astrophotography and Fossils are my big three personal interests among many others. Wife and family are always first but balance in ones life is also a good thing. Enough rambling. Packed the gear for fossils and stars, food, drink, personal safety gear, eye drops ( gotta have it in a dusty desert ) gassed up the Element and I'm off. Never gets boring scenery. Heading over the summit pass @ 7500 feet. First stop was a previous site, Garley Canyon, which was barely thawing the ice and snow with plenty of mud. This time it was dry and I turned in to look for the orange outcrops containing ammonites. Had to visit one of my favorite cacti - Scelerocactus vivipara - the small flowered fishhook cactus. This is an exemplary specimen. Usually BLM land have so many open range cattle that they get squished before growing up. I drove around looking for those orange mounds of possibilities. All the way to the cliff. Not sure what this was besides guessing and worth a photo. Nice, HUGE, slab of inchnofossils, which I left in place. I drove around and did not quite hit the spots where the orange outcropping were to be found. The website I researched had been posted back in 2009 and with time the jeep trails were much rougher and washed away. I also had a timeline to catch a museum before its closure at 4 pm. This canyon and the orange outcroppings weren't going anywhere and miles to go before I don't sleep this night. Second stop is a rockhound mecca. Septarianville also known as the Dragon Egg Nest. Supposedly the only location with red interior septarian nodules. The more common variants are yellowish calcite interiors. We have a nice yellow one and my wife gave the green light for a nice red one to go with it. Here's the turnoff sign. I go down the gravel road a few miles and spot the sign...hmmm.. the sign is a little worse for wear than the online pic and the site is deserted. No tents, no big excavator, no tourists/visitors. I called the number - no answer. The web says open until 8 pm. I'll be following up on this later. They probably have a summer season only. IDK. The site courtesy the big eye in the sky. What the red ones look like. There is online a blogger's site where he drove one mile past this site to find large ammonites in concretions weathered out of the hills nearby. So I find said hills and start checking out the likely spots. It's a dead end road with hills...I couldn't miss it. And I didn't. However there are a lot of hills, ravines, climbing and hiking around and the concretions are few a far between. In fact, I'm not seeing any at all. So on to the next hill. Ahhh! I see a few which have been hammered open. The usual suspects inside. Bivalves, gastropods and some evidence of small ammos. I checked every broken concretion carefully, as I had found at other sites that more than a few keeper fossils were overlooked. Not this time. Just lots of crumbled concretions with many being calcite veined only and Inoceramus bivalves along with gastropods were all I found. Where were the reputed "large ammonites" ?!? Here's a sample of the few concretions found. In the center of this piece I noticed a olive shaped smooth fossil shell. With a little, lite taps I and put this & another into my empty bucket. I believe I found samples of Birgella subglobosa or B. burchi. Not sure. Daylight was waning and I had 50 miles to get deeper into the desert for the evening under the stars. Along the hike back to my car. I noticed a few surface finds of trace fossils. I collected the first one. The sun set in the west as it does and in the east a celestial phenomena occurred; The Belt of Venus appeared. It only lasts a short while so my image captures were spontaneous cell shots out of the window as I drove. On to the desert astrophotography destination. An early evening image before the Milky Way rose in the wee hours between 2 and 5 AM. Jupiter, Orion the Hunter and the Pleiades are heading south for the summer. And the Milky Way season is ON! A rare mud puddle added some interest in the reflection of the stars. A short nap between 12 and 2 and then between 230 and 5 I captured many images of the Milky Way galaxy. Afterwards, another short nap and back to the fossil hunting. First stop, the Castle Dale museum, second stop the Jurassic National Monument, third stop meeting new friends and sharing the excitement of finding amazing ammonites. I also have an interest in ancient American pottery and craft replicas of this type of pottery using locally found clay, slips, organic and mineral paints, primitive tools and outdoor firing techniques used by those original potters. This specimen is from the same location where I collected mine late last year on one of my earliest fossil hunts. And I'm going to post this now to not overload the thread with MB's of images. Next up is the Jurassic National Monument and a few pics of the ammonites found after visiting the Cleveland-Lloyd dinosaur quarry. Steve
  12. Hello, I went searching in the Callovian Lower Oxford Clay at Yaxley, and I found this small tooth, measuring 6mm across. Could it perhaps be Hypsocormus? Aside from the tooth, I found a few crinoid ossicles, annelid tubes and the pyrite ammonites from the Oxford clay are stunning, I think I found several Kosmoceras, possibly Peltoceras athleta and Quenstedtoceras lamberti. I have attached a few photos of some of the ammonites too. Thank you.

  14. Hello, I would like to know if this tooth may possibly be from Yangchuanosaurus species. It is from the Shaximiao Formation, Zigong, Sichuan Province, China Formation is Jurassic age and relatively very little material is known from this formation and particularly in China although seems like Yangchuanosaurus has been described from this location et al. (1978) named Yangchuanosaurus shangyouensis on the basis of CV 00215, a complete skull and skeleton which was collected from the Shangshaximiao Formation, near Yongchuan, Yongchuan District, Sichuan. Tooth measures less than 2 inches and the serrations appears too worn to make an ideal identification, although looking at teeth from skulls of Yangchuanosaurus, they do seem very similar , in shape and size Any help would be appreciated! Thanks!
  15. The Theropod Dinosaurs of the genus Allosaurus since their discovery in 1877 are perhaps one the most recognizable theropods of the whole Jurassic period (201.4 ± 0.2-145.0 Million Years ago) despite emerging only in the late Kimmeridgian stage of the Jurassic period. Growing up to 9.7 meters (32 feet) in length fully grown, Allosaurus (also known as the Lions of Jurassic) were the apex predators of most of the terrestrial ecosystems they inhabited. The only theropods from these time that were higher in the food chain were some European non-Allosauroid Theropods and other members of Allosauroidea including the much rarer Epanterias (validity debated, possibly grew fully grown up to 12 meters (40 feet) in length) and Saurophaganax (validity confirmed, fully grown reached 10.5 meters (34 feet) in length).

By artist Frederic Wierum Image Source: https://fredthedinosaurman.artstation.com/projects/Qg0WB The Allosauroids eventually gave rise to some of the largest theropod dinosaurs known in the fossil record currently including the closely related South American genus Giganotosaurus from the Cenomanian stage of the Late Cretaceous period (99.6-95 Million Years ago) in what is now Argentina (which fully grown grew up to 12-13 meters (39-43 feet) in length). But Allosaurus itself has largely been considered to have lived only in the latest stages in Jurassic period (155-145 Million Years ago). I have found some records that might challenge this assumption!!! Digital Reconstruction of an adult Allosaurus sp.

  17. The Triassic-Jurassic Extinction Event of 201 Million Years ago is less talked about at times than the Mass Extinction events at the end of the Permian and the end of the Cretaceous, but was still an incredibly significant extinction event in Earth’s geologic history. P. Olsen et al. Arctic ice and the ecological rise of the dinosaurs. Science Advances. Published online July 1, 2022. doi:10.1126/sciadv.abo6342. https://www.science.org/doi/10.1126/sciadv.abo6342 Caused by volcanic eruptions that would eventually break apart Pangea and form the Atlantic Ocean, about 23-43% of marine genera (including 96% of coral genera at the time) was wiped out alongside between 17-73% of plant genera at the time. On land, archosaur diversity was decimated. Phytosaurs, Aetosaurs, and many others primitive archosaur groups were wiped out. But one major group of archosaurs that survived were the dinosaurs (Dinosauria). Emerging first in the middle Triassic, dinosaur diversity was hit hard by the event. But the group was overall able to survive thanks to adaptations such as a mostly warm-blooded metabolism and (for theropod dinosaurs) feathers for warmth. Some of the first true mammals including Morganucodon also survived the event, but they would take more of a backseat until the end of the Mesozoic era. For the Dinosaurs, the survivors of the event would go on to diversify, increase in size, and dominate Earth’s terrestrial ecosystems for the next 135 Million Years as they become one of the most successful animal groups in Earth’s history. Here’s a list of all currently known Dinosaur genera and families that survived the Triassic-Jurassic Extinction Event. If I forget any examples, please let me know and I'll add the examples to the list promptly.

    Any ideas?

    Hiya, found this in Southerndown, Wales. I think it could be bone but I dont know. And even if it is bone, I've no idea what animal it'd be from. This site is jurassic 200-190 myo. Any help is appreciated, thanks!

    Oxford Clay Teeth

    Below are two teeth from the Callovian of the Oxford Clay. The left was identified as Hypsocormus tenuirostris, and the right one Teleosaurus sp. I thought it would be worth verifying both IDs, given how difficult some Jurassic marine reptile teeth are to identify. It is my understanding that @pachy-pleuro-whatnot-odon has great expertise with regards to Jurassic teeth. What do you make of them? Thanks in advance for any guidance Othniel
  20. Hello! I found this fossilized bone a few days ago after the big tides in the Jurassic of the Boulonnais region (North of France). I can’t seem to place it… The cell structure looks dinosaur to me, not marine reptile. Would anyone be acquainted with this type of material and have any idea? Thank you very much! IMG_0855.mov

  24. In past, I was afraid of the tooth damage, so I put adhesive on the tooth. But adhesive parts turned white, because it didn’t dry properly, so I requested an acquaintance to restore it. Fortunately, removing adhesive was successful. Due to, the striation looks clearer. Here’s check it. Lastly, more closer striations.
