  1. Central Texas has been experiencing a surprisingly cool September plus quite a bit of rain! And that equals some great fossil hunting! I have gone to a few old spots and a few new spots! All in the Cretaceous Glen Rose. I am just constantly amazed at the amount of fauna in the Glen Rose. It seems like I find something new just about every time I go out! I was happy to find a new species of echinoid - a Goniopygus sp. ( very different from the previous Goniopygus I've found) It's tiny tiny, only 5mm. And I found my first really good vertebrate material - a Pycnodont jaw with teeth and a large piece of turtle (plastron?). And even thought it's no echinoid...it's still an echinoderm - my best find of the month so far....a free swimming crinoid! I had never seen one of these but thanks to the Paleontological Society of Austin and our latest field trip, I found this lovely odd little thing! Plus some good Heart Urchins and some nice little Loriolias. Goniopygus sp. 5 mm Free Swimming Crinoid: 1/2 inch (1 cm aprox) Pycnodont Jaw with Teeth 1 inch A small Cidarid Fragment and some Leptosalenia and Cidarid spines A nice Heteraster obliquetus: 1 1/2 inch A decent Pliotoxaster comanchei. 1 1/4 inch A nice little Loriolia rosana 1/2 inch Turtle bone fragment 2 inches
  2. Took a little trip out to West Texas last weekend. My parents have friends who have ranches out near Balmorhea (great to have friends with ranches...everyone should have friends who have ranches!). I knew the general area was one I had wanted to go hunting for echinoids in the Boracho Formation (some very special echinoids not found in my area). I did my research on Google maps and the Texas Geology website, hoping I could pinpoint the right roadcuts! The first one we stopped at (I thought was the right formation) turned out to be a different formation, but I found some cool little brachiopods that are different than any i have encountered before and a couple of echinoids (phymosomas) and that was all for that little roadcut. Checked out a few more in the area but didn't find anything. Definitely didn't find what I was looking for! So on to our weekend at the ranch. The owner said he know of a "beach" on the ranch where "sea shells" were found. I was really surprised because on the Geology map it is all Igneous and Quaternary - nothing at all that looked Cretaceous fossiliferous. So we went driving around the ranch to the spot and to my GREAT surprise, we found an outcrop of Austin Chalk! I don't know how, but it was there! I found inoceramus clam parts and some of the most beautifully colored Exogyra erraticostata! So that was a really special spot! ( @grandpa -another "fossil that shouldn't be there!"- but it was!) The final day we were to head home, I convinced my parents to drive 30 miles further West before we headed back east for home. I knew there were supposed to be some more outcrops of the Boracho accessible so we took a little side trip and happily I found the formation I was looking for! And I was rewarded with a most LOVELY little Anorthopygus texanus echinoid! I initially thought it was a Coenholectypus transpecoensis (which was mainly what I was hoping to find -which I did not find!) but was happy to discover it was a more rare Anorthopygus! My mom found a nicely presereved Wahitaster wenoensis, so that was great too. I also found a phymosoma, but it's pretty beat up. A small section of a nautiloid and a nice bivalve which I think is a Lima wacoensis quadrangularis rounded out my day. So it was a good haul to West Texa! My best finds from Boracho /San Martine formation Anorthopygus texanus - 25 mm : Washitaster wenoensis 25 mm a not so great Phymosoma 1 1/2 inches Lima wacoensis quadragularis 1 inch From the Austin Chalk Formation on the ranch: Exogyra erraticostata 3 inches From the first roadcut which was Buda formation Kingena (Waconella) sp? what's odd about them is this "dip in the lip" so I am not sure what species it is (it is for sure Cretaceous Kingena/ Waconella and not a Pennsylvanian Composita which it very much looks like -we had a nice long post on that!) A few pics of some of the critters on the ranch: Auadad (not native, but gone native) Javelina mama and baby! A mule deer wild turkeys
  3. I made a trip to the Lake Texoma area yesterday, to hunt a Duck Creek outcropping on a bluff. This was one of those trips that turned into more of an adventure than I bargained for. The hike from where I had to park was a lot longer and more arduous than I anticipated (it always looks easy on a satellite image, doesn't it?), and it ended up being one of those situations where I just couldn't come back the way I went in. So, I ended up getting lost, and hiking a much further distance on the return, with a heavy backpack. I should have taken a moment to mark on gps where I parked the van, and didn't do it. I won't make that mistake again. Even when you don't have wifi or cell coverage (and I didn't), gps works, and I'll use it better from now on. I wouldn't have been able to make anything close to a straight line hike back to the van, but would have done a lot better than I did. When you end up making an unexpectedly long hike with a heavy backpack on a humid ninety something degree day in July in Oklahoma, you run out of water. That iced tea in my lunch ice chest in the van was very welcome when I finally got back to it. This is a great fossil hunting spot, but I think I'm putting it on my list of spots for milder weather times of the year. Once I reached the bluff, I couldn't believe how many large ammonite fragments there were. Every five steps I took, I saw another, and took over thirty photos in short order. Here are a few representative photos. Keep in mind that chisel is 12 inches (30 cm) long.

  6. Boy have I been away for a good bit. Quite a lot has happened since! Hope everyone's doing all right all things considered! Seeing the calamity the world is in the throes of, I decided to head out Saturday before the zombie apocalypse truly took hold here in GA. With social distancing and whatnot in effect, the options are quite limited as far as recreational activities. Thankfully, everyone's favorite activity, finding the rock-encrusted remains of life long gone is something that can be done away from prying eyes, particularly the Tivola Limestone site in Perry GA that I visited last year that produces those gorgeous Periarchus sand dollars and Chlamys scallops. After a quick pit stop at a hazmat-ified Chick-fil-A and a nice drive to Perry, we found ourselves at the site for the second time. After a short walk through mild vegetation, the abandoned quarry came into view: The rock that made up the walls seemed to be significantly darker than what we observed our first time around, a result of extended exposure to the elements. After a few early finds on top of the pit's edge, we made our descent inside via a small and less steep slope hugging a portion of the wall. In the pit, 2 hours were sunk into searching. The result: a decent haul, with a lot of prep-ables. The first thing I picked up was perhaps my favorite: an in-situ Periarchus pileussinensis that was mostly whole, with a number of small cracks visible that served to put a kind of emphasis on its age.
  7. Late Cretaceous marine sites in China

    Hey Would anyone know of Late Cretaceous fossil sites in China that are similar to 'typical' Late Cretaceous marine sites in Europe/North America? Like places where one can find ammonites, sea urchins, shark teeth and mosasaur fossils... Thanks for any help! Christian
  8. Amazing clusters of echinoids!

    Hey guys hope you're well! I wanted to show you the amazing lovenia woodsii clusters I found today at Beaumaris, and ask for some advice. These are lovenia woodsii. Some still retain amazing detail, like the final pic! Do you guys have any recommendations for coating the sandy matrix the woodsii are sitting in? I would like to prevent them becoming too brittle upon drying out.
  9. Hello everyone! At this point, it's been a long time since I've found any of these so I wanted to show my collection of Wenonah slabs or 'plates'. These slabs were found in the same area over the course of a few years and is a collaboration of a lot of fun trips with friends. The majority of them were found by me and my brother, Shane @shajzer64 in 2016 but a few others have dug with me in this (mostly unproductive) location looking for and finding these - thank you to everyone involved! The slabs are all the same thickness and preservation; I was actually able to put a few together but as a whole, I think most were in the stream for too long to connect them. They are mostly shell and gastropod imprints but include ghost shrimp burrows, an Ischyrhiza rostral, shark teeth, an echinoid, an ammonite, a fish spine (we think), scaphopods, and more. I'm not positive the sponges are associated with this exact project but the preservation looks the same so I included them too (that could go for the ammonite too). If anyone is interested in seeing a particular slab, let me know and I'll get a picture. I'm pretty happy with my new display so I hope you enjoy it! -Frank @Carl @non-remanié @Darktooth@Jeffrey P@Trevor@The Jersey Devil
  10. Hello members of TFF I'm looking for echinoids (sea urchins/sand dollars) to increase my collection of this kind of fossils. I'm interested in all kind of echinoids but what matter for me its the state of conservation. I have for trade several types of fossils from miocene (shark teeth, bivalves, gastropods...), cretaceous (echinoids, bivalves, gastropods) and Jurassic (echinoids, brachiopods, vertebrate material...) Thanks Vieira
  11. I am TRYING to figure out my pliotoxasters. I think i have three different species and am hoping for some confirmation or information! I grouped them into similar seeming "batches" and think these are the ID's but would appreciate any help. All Texas Cretaceous, various formations, mostly Walnut I think. These I believe are Pliotoxaster whitei Side view: These I believer are Pliotoxaster comanchei Side view: These I think are Pliotoxaster inflatus: side view:
  12. Had a lovely day out hunting with a new fossil friend - @Nuna! She said let's go hunting in Austin - i know a spot! Turns out that spot was the creek near the house I grew up - lived there from age 6-17. I had not been back in a long long time.. and I certainly have not been in the creek since I was probably 10 years old! I realized that my earliest "fossil memory" was going to the creek with the neighbor kid Jimmy to hunt for fossils when we were 8 (2nd grade I guess?). I remember we found brachiopods... He then invited me to go to a Paleontology Society of Austin meeting. I remember being the two youngest there, for sure! Now, flash forward 40 years and i am now a member of the PSoA (joined a few months ago). So Nuna, her awesome dog Mack and I head down into the creek. It is absolutely beautiful. I did not know there was an easy access, we crawled down the culverts to get there in the past! I am not adverse to crawling through culverts, but am happy not to! We poked around, found those brachiopods! plus a few other little things, a few ammonite chunks. Then we found the sweet spot. Some of the biggest Neithia bivalves I've seen, lots of brachiopods, I found a lovely big Leptomaria gastropod, a broken Pecten wrighti and a little ammonite (Nuna found the good ammonite of the day) and some other nice stuff. But then I found a little chunk of something that I was not sure....but recognized it as fossil. And then I found a whole one....a gorgeous cidarid spine. And found another. Never found the body, but I love those spines! A few feet further, i see what looks like a heart urchin (of which there are LOTS in Central Texas in certain locations) so I was happy, but not super excited, until I realized it was a bit different than what I had found in the past. Turns out it is a new to me species - Holaster simplex! So a nostalgic walk in the park became a bonanza echinoid day for me. Big thanks to Nuna for taking me "back to my old hunting grounds"!!!! Based on the stuff we found, I'm assuming this is Georgetown formation.....any corroboration? Leptomaria gastro Pecten texana: ( i love the red coloration on this one) Pecten wrighti: Brachiopod Kingena: Echionid Holaster simplex: Cidarid Spine :
  13. I made a "concentrated" study of the Georgetown formation -about an hour north of me (I usually hunt in the Glen Rose and Walnut of Texas) so it was fun to hit up four spots to see what different species I could find. I was happy to gather a good variety of specimens, including a couple of "best" specimens of common Texas finds - a lovely BIG Neithia scallop with both the top and bottom valve intact, a nice Ostrea carinata and lots of well preserved turritells, including the tiniest I've ever found. But the fun stuff is the Echinoids and the Ammonites! For the Echinoids: I FINALLY found a Salenia Mexicana (that didn't crumble in my hands like the LAST one I found) even if it is a bit water worn. I'm still happy with it. Plus an excellently preserved Heteraster obliquatus and a nice Phymosoma which is still encased in a bit of matrix, but that's okay. But my find of the day was the Tetragramma taffi (i'm pretty sure on that ID, let me know if I"m wrong!) Even thought it's quite squished and has a lot of matrix, it's still my first one, so I"m stoked!! The "other" fossils: A pyrite shell, not great, but cool because it's pyrite The Echinoids! Phymosoma Salenia mexicana: Tetragramma taffi a nice Heteraster:
  14. Joining the Paleontological Society of Austin has been such a good thing. I am learning more about where to look and what to look for! Experts are so....expert. So we went to a place I had been before, but apparently I was not looking "small" enough. Although I did find some lovely Cretaceous crinoids on my first trip and a nice smashed Pygopyrina, this time, I looked even closer and found not only more crinoids (love those little stars!) but also a tiny Pygopyrina hancockensis and some Leptosalenia (juveniles supposedly), which is weird because no larger ones are apparently found at that site. Maybe they migrate somewhere else? Anyways, they are tiny tiny tiny. And I was super happy to find something new : a few plates of an Echinothurid. These echinoids apparently disarticulate once they expire so usually all you find are these little sections. Still pretty cool. Also, found another nice sized Coenholectypus and some nice examples of Salenia texana at another site nearby. A few days later, I was poking around a new to me site and found a lovely big crab claw, but my find of the day was ANOTHER tiny section of a Pseudodiadema. I am dying to find a full one, but they are apparently rather rare. This is the third "chunk" I have found. Someday soon....perhaps I'll find a whole one. But I"m happy with my "llittle things" because it's the little things that make life such a big deal (to steal a phrase from the Austin band Timbuk 3) Scale is inches The Tinys: Echinodthurid plates: Coenholectypus Salenia texanas: Pseudodiademas (the small bit I found yesterday, the larger bit was from last year) Crinoid Isocrinus Some Crab Claws (not an echinoderm obviously, but I mention them in my post and you might just want to see them)
  15. North Carolina River Finds

    Hey everyone, here are a few pics of some zone 2 Pliocene Yorktown Formation finds and some Spring Garden Member Eocene Castle Hayne Formation finds from an eastern North Carolina River near my house. Pecten, not yet ID'd. Pliocene
  16. Fossil Road Trip - Georgia, Texas

    Both my brother and I celebrated graduations this year - my brother graduated from college and I graduated from law school. In celebration of our graduations, we decided to take a 13-day road trip to see some of the United States after I had taken the bar exam but before I began work. Our journey ultimately took us through Atlanta, New Orleans, Houston, San Antonio, Austin, Oklahoma City, St. Louis, Dayton and Pittsburgh, before returning home. Our days were jam-packed, with us often not arriving at a hotel until 9/10pm, but along the way we did find some time to make a few quick stops to collect some fossils in Georgia and Texas. My brother is not a collector, but I was really excited to try to find some examples of the infamous Georgia trilobites, Texas echinoids and Texas ammonites. I want to thank @BobWill, @smt126, @facehugger, and @JamieLynn for answering my innumerable questions about Texas fossils. We ultimately did not have enough time to check out all of the places you suggested, but I will certainly store the knowledge for my next trip - hopefully in cooler weather. Our first stop was at Tibbs Bridge in Chatsworth, GA. Having heard the rumors about the potential illegality of the site I was a little worried when we arrived. We could not initially find parking and when we pulled off, we picked the wrong spot. The homeowner we parked near came out yelling at us about collecting beneath the bridge and threatening to call the police. Having driven all the way from New Jersey I was not yet ready to give up on the trip. We decided to pick another spot to park and given that my brother doesn't collect, he waited in the car in case something happened. We could not stay at the site for longer than 90 minutes, so I tried to find as much as I could. As a funny aside, I was soon joined by another group of collectors from Georgia, one of whom had recently spent time in my hometown in New Jersey. Small world! I was hoping to find some better preserved trilobites, but I had to ultimately settle with some nice impressions and a couple of smaller fragments of exoskeleton. I did find one large trilobite that still had all of its exoskeleton, but it was fractured and I could not put it back together even at home. I was able to keep the impression of the trilobite though. All of what I found were Aphelaspis brachyphasis. And the large trilobite whose exoskeleton was simply too damaged to repair
  17. Went out with the Paleontological Society of Austin Saturday for a field trip - yes, in Austin Texas in August (not usually a great idea) but we went early to beat the heat and had an unusually cloudy morning with very low humidity, so it was actually VERY pleasant! We hit up a Walnut Formation road cut with lots of lovely gastropods (Anchura, Tylostoma and Gyrodes), some rather uncommonly found Parasimilia corals plus a variety of Echinoids. I found a large 3/4 busted up Phymosoma, a number of little Loriolias, and a couple of nice Heteraster Heart Urchins but my faves were a BIG kind of busted up Coenholectypus and a tiny Coen too. I picked up a number of other things, including what I THOUGHT were two squished Porocystis globularis (Algeal Fruit) which when I got home, turned out to be two nice middle sized Coens very very encrusted in limestone...so much so I did not recognize them in the field. So I thought I'd try the vinegar soak I'd heard about. I have been hesitant to try but since I already had a couple of decent specimens of Coens, I thought I'd try. WOW. Just WOW. I forgot to take a before picture, just know that they were barely recognizable! After that luck with the Coens, I decided to try it on a Goniopygus that was so encrusted you could only see a small section of it. I am SO excited with the way it turned out! So yay for vinegar soak! Vinegar soak on the Goniopygus
  18. Echinoids

    The first 8 are echinoids and echinoid spines, I have seen plenty of photos of them while researching forams. Doctor Mud.....I can not confirm it but I do think you may be right about the last two being some sort of echinoid, This thing is only about a half a millimeter in size, I can't find anything online that looks like it but will keep at it.
  19. Maastrichtian fieldtrip in Belgium

    Today @Natalie81 and I went on a field trip with our geology club to the quarry of Eben-Emael In Belgium. We were over 50 participants today an I had the oportunity to meet aan other TFF member @ziggycardon This location is not far from the stratotype in Maastricht in the Netherlands and a multitude of fossils can be found in the marls and chalks. We had a slow start, but after searching through scree piles I found a small and a big sea urchin, and later on a few belemnites. Natalie hadn't got much luck at the start of the prospection, but she did eventually find the find of the day: a fragment of a turtle shell ( Allopleuron hofmanni ) with a few verts in association. We did have a great day and Ziggycardon had also his bag full of fossils and a great first fossil fieldtrip. the quarry: Maastrichtian marl ( formation of Emael ) Ziggy in action Natalie's turtle fragment: Home with the finds: A quick cleanup of the big sea urchin: Hemipneustes stratoradiatus
  20. Finally getting round to identifying some finds from over the years at different sections of Big Brook, NJ. I'm going to try and post them in separate topics. The white sea urchin spine is distinctive, but what are these other things? They have similar dots in lines, but the lines are much more spread apart. See that they have pointed ends and one has a wider end. They are about 2-4mm in diameter. Also, any idea or pointers as to what species the Sea Urchin spine could be? I haven't found an easy identification guide on the web yet.
  21. Hey folks maybe you can help me out. Especially the European collectors. Here in Texas we have historically had several species of Tetragramma listed as occurring in the Fredericksburg Group (Albian) that are possibly synonymous. For those of us who collect here in Central Texas there never seemed to be any doubts about what was a Tetragramma malbosii versus a T. taffi. T. taffi are always larger and seem quite distinct from T. malbosii. (see my two examples) But in 2016 William Morgan wrote the Collector's Guide to Texas Cretaceous Echinoids (Schiffer Publ.) and in it he lists T. malbosii as having precedence, suggesting that they are just not as full grown as taffi. He sites the work of Smith & Wright, 1993. I know T. malbosii is found in Europe. What about T. taffi? What does a very large European T. malbosii look like? The one I am using as an example is the largest one I have but it is still not as large as the T. taffi and doesn't have nearly the same number of tubercles in the interamb. Your thoughts, opinions, observations, etc.??? And if anyone can point me to a link or a PDF of the following paper I would greatly appreciate it and could reward with a nice Texas echionoid...

  22. Hey TFF Members! Cris and I were able to get out and do some super fun Echinoid hunting earlier this week! We were able to find some very nice specimens from the Eocene. If anyone has an ID on the big thick one I found in the video, please let me know! We got stuck in some nasty storms on this trip, but were also lucky enough to see a stunning rainbow! It was a great trip. Check out the vid if you get a chance!
  23. In the continuing saga of finding all the echinoids of Texas.....I found a few new things plus re-assessing my collection I found I already had another example (albeit small bits only) of another! So here are my latest finds (and re-finds). In my collection from Marathon Tx was a couple of bits of (I think) an Archeocidarid!! Stopped by a little creek in Austin and found this lovely Coenholectypus: Went on a little road trip to Glen Rose TX and found what I thought was a Loriolia but on closer inspection, it's a Goniopygus! Not a great specimen, but slightly better than my previous ones, so still looking for a nice one: And the piece de resistance : A Balanocidarid Spine!! Practically in my own backyard (well, within 30 minutes drive anyways)
  24. Hey have others been having trouble with the British Museum's online Echinoid Directory? It has been off and on for the last week or two and currently I can not get the Keys, Index to Taxa or Glossry to open. Hoping some of our friends across the water might have a little insight. https://www.nhm.ac.uk/our-science/data/echinoid-directory/
