My faithful assistant and I found a clump of dirt/clay/rock on a creek bank. The creek has a couple long and steep hills that look Ozan-ish. Well, I took the clump home and slowly wiggled it apart. That clump held a couple of small teeth, tons of tiny little shells, and this mystery object. It's less than 1mm and very tooth like. I can't seem to match it to anything. Ideas?

Hello everyone! While I was cleaning out my phone I forgot I had these finds that I would like second opinions on identifying from Post Oak Creek near Sherman, Texas. I found these right before I had to fly out to Iceland so the setup is very messy and was done quickly. I love hunting here, and have a general understanding on most of my finds there which are mostly various shark teeth and lopha oysters. Usually confident in identifying however I never got to go to school for paleontology so I’m still an amateur! Im always so eager to love to learn more about the ancient Cretaceous sea life even if it can’t be my profession. Here is the layout! Sorry again it’s so messy! I spilled water. (Ballpoint pen and cavendish banan for reference) ……………….. I found a LOT of Ptychodus whipplei that day! I was super happy as this is my *favorite* shark. I came mostly looking for these babies so my attention was focused on searching the gravel for these shapes specifically. Anything else I found was a happy mistake. Never found so many in one trip! Just showing these off really quick! Hopefully they make someone here smile! What is the one I have labeled 13?! Never seen it before! I also found some goblin sharks, squalicorax, and psuedocorax. ………………. I would like help IDing these mammal looking parts! I understand that there’s probably a bunch of pig and horse farm animals locally that have died… but I wanted to ask about these! I think the long orange one is from a horse(?) that was split in half and not sure what the other bones are from. They feel a little in the lighter side but feel weighty and “stone” enough to be possibly fossilized. I have no idea how to ID what a mammal bone is except teeth! I also think I found the TINIEST arrowhead ever! At first I thought the triangle shape was just a coincidence of a chert fracture but look-there’s chisel marks! Maybe a stone tool that the very tip broken off. Either way I’m glad I kept it! M1 pig bone? M2 ??? Mammal tooth M3 horse tooth? M4 arrowhead tip!? *hopefully* these are enough pictures to help ID these four! So neat to find mammal remains as Ive only found both devonian & cretaceous marine fossils in my life. ……………….. Mystery Swirl! I find this specimen’s shape intriguing. It looks like an internal mold of a snail but looks swirly and not perfectly tube shaped as a snail would stike me as- it looks like a little like a poop! Wondering if this is snail mold or possible coprolite! It doesn’t look straight and as “segmenty” in clumped wads as my shark coprolite from NSR I had ID’d. Im leaning towards snail. I just love that it looks like do-do. ……………….. I would also love having help ID these Cretaceous finds! Im a familiar amateur with the local Cretaceous stuff but not an expert. I would love to be educated to ID specific species of sharks to help local people I meet here ID their finds! ……………….. I found 2 interesting fishy looking teeth! Thanks to this forum I found a jaw of Enchodus back at NSR a while ago, this little one reminded me of that! I found this longer looking tooth that I have no idea if its a marine reptile or fish! It’s long and skinny with long striations all around it and round all around. The tip is broken. **Would LOVE to know if theres a trick to instantly knowing a fish tooth from a marine reptile tooth. I think I read on another thread a while back that one of them lacks a layer of something in the enamel but I’m probably wrong. F tooth 1- teenie Enchodus? F tooth 2- saw shark ? ……………….. Need help with P 13. It reminds me a little of a ptychodus tooth but I couldn’t find anything in the pinned ptychodus ID thread that looked like it. Maybe a worn P. Mortoni , but maybe possible it could be something else entirely! Check the first 2 photos I posted for size ref and more photos of it. I regret not taking a pic of the back. I know most of my ptychodus are P. whipplei (the common ptychodus to find at Post Oak!) but the others after P11 are new finds to me and not in any of my favorite references. ……………….. Lastly- would like to know if these are cretolamna or leptostyrax and how to easily ID the two! I use the fossils of texas book as a reference and some of them look so similar its hard to tell them apart for me. I usually find mostly the common but awesome goblin shark teeth (scapanorhynchus) but every once and a while I find some that look like these. Im leaning towards a bunch of them being cretolamna. *might be a few broken or worn goblin shark mixed in here Thanks for taking the time to read all of this! I hope the pictures were enjoyable! Id absolutely love to learn more about Cretaceous marine life when I get back to Texas from Iceland. (I went to the Heard museum and Perot right before I left!) ** Additional photo of arrowhead looking piece that uploaded out of order: ***Bonus pictures from that day! I can assure you this area is not totally picked over I found these near the Bridge as shown in the photo.

I found this little tooth...or at least part of a tooth and I can't figure it out. It's 1 cm wide...I'm assuming it's the chewing surface of a larger piece...but to what? Thanks for any help with this ID. SE Texas.

Is this little guy a raccoon femur? It's about 12 cm long...found it in the sand on a bank here in SE Texas. Looking online it seems to fit.

I decided on a whim to make the trek to the North Sulphur River ONE MORE TIME before they dam it up and the good hunting spots are under 60 feet of water. I wasn't planning on going back, as I have not had much luck on the NSR finding my most desired thing....a Texas Mosasaur Tooth (or Vertebra...I'd settle for that even!) but a friend from North Texas was going to go and he KNOWS that river so I figured I'd tag along and maybe, just maybe, this time, the NSR would give up the goods. So I drove the 5 hours up and met up with my friends and had a nice long 6 hour hunt. (and then a 5 hour drive home....a long day). Alas, my fossil treasures were not to be found. We had a great time and I found some great stuff, but that dang Mosasaur eludes me still. The day was GORGEOUS. Partly cloudy, 77 degrees F, there had been rains recently and we went in at a spot about 3 miles upriver which saved us the 3 mile hike through the mud to get to the "good spot". The water was receding rapidly, so although not as clear as it is sometimes, it was only knee high at the deepest. We hit all the gravel bars on our trek up with some success, but not as much as we'd hoped. I found some bone material, including a large fish possible jaw fragment, and did find one vertebral process and a small rib bone that are nice. My friend had the find of the day, a nice little jaw section with some tooth sockets. He decided to keep that one. But at least I got to take a picture! We found a nice exposure of the red beds and I managed to find a full Trachyscaphites which was my find of the day, plus a couple of partials of a few ammonites I've not found before. I found an almost decent take home of a Glyptoxoceras. It's not the best, but more complete than I've ever found before. My REAL find was a very nice shark vertebra and a fish tooth, possibly Enchodus or Xiphactinus fish tooth. Leaning toward Enchodus. If anyone can confirm, I'd appreciate it! So I never found my Mosasaur Tooth or a vert, but I did have a lovely time wandering along the river, getting my feet wet and the odd patch of poison ivy. It was worth it, but I suspect it's my last trip to the NSR. Some you just leave them where they are: THE find of the day: Mosasaur Jaw fragment. Size 2 inches Rib Bone: 2 inches Large Fish bone, jaw maybe Size 3 inches fish tooth Size 1 inch Shark Vert Size 1 inch My lovely little Trachyscaphites spiniger Size 2 inches Glyptoxoceras Size 3 inches Pachydiscus paulsoni Size 5 inches Mosasaur Vertebra process Size 4 inches Another Mosasaur chunka bone. The Full Hoard

Greetings. Working through my prep pile, I got around to putting the scribe to this tooth. I assume it is a plesiosaur/pliosaur tooth as opposed to some kind of fish, but I'm not sure. I'm curious if someone more knowledgeable could assign this tooth to a genus, if there are sufficient diagnostic features showing. Eagle Ford Group, Balcones Fault Zone, Texas. Thanks

Found this little artiodactyl tooth on one of my trips to the Colorado River near Wharton, Texas about a month ago and have had some trouble getting a concrete ID. Any teeth other than bison or horse are basically impossible to find in the Brazos and so I'm way out of my depth with this one. I'm assuming it's too small to be camelid and the pictures I've seen that most closely resemble it are of antilocaprid teeth. This one must be an m3, the third lobe is just broken off (which you can see pretty clearly in the third and the fifth pictures). The occlusal surface is 1.5 cm across but obviously would be longer if the rest of the tooth was still there. As always, thanks for looking, and I'd be incredibly grateful if anybody can confirm my suspicions or point me in the right direction. I'll tag some of the Pleistocene experts that have been particularly helpful in the past: @Harry Pristis @Lorne Ledger @garyc @Shellseeker - love that these guys are a part of this forum!

Hello, found this last Saturday at a beach in Galveston Island, Texas. Other fossils I’ve found there, are from the late Pleistocene (only around 20,000 years old). They come from the Beaumont Formation. I know this piece of bone is almost certainly from a fish. Does anyone recognize what bone this is, and from what species? It has a very weird shape, and something tells me that this is probably from a skull, possibly something similar to a sea robin skull plate. Measures around 4.75 cm (1.87 inches long)
