Marine reptile. Mosasaur vertebra from Austin, Ozan Formation. 11/6/21 -
Hi y'all, I bought some shark vertebrae here in the Netherlands from a guy who collected it himself in Gainesville, Florida area, a couple of verts are not from shark including this one and i was wondering from what animal it could have been. I hope one of you has an idea what it could be. Thanks!!

A bit of a vertebra theme tonight so thought I'd jump in, found this in creek in Cretaceous Eagle Ford but the area is QT and QAL also. It's not fully mineralized just like most bones from around here, I think it looks like croc but it's very worn so could be wrong.

With the end of the semester approaching, school has picked up and I have been too busy to embark on many adventures. When my schedule finally cleared up one afternoon following a brief rain in Austin, I jumped at the opportunity to do a bit of exploring. One of my goals right now is to check out new parts of the creek I hunt on. Scanning through my list of potential spots, I decided to try and be the first one out to a very promising location. Like my previous hunts, this place ran through the Ozan formation, so my expectations were set on some nice Cretaceous specimens as well as the usual native artifacts that Central Texas is so famous for. After I parked and carefully scaled my way down to the water's edge, I was immediately met with several pairs of shoes and jackets. Thinking I had been beaten to the punch, I decided I might as well head down the stream and meet whoever it was to discuss the location and fossils in general. Thankfully, the trip was saved when they turned out to be a kind group of fishermen. After a brief chat, I carried on to get the hunt started. The mud was an absolute nightmare. I had never been up to my knees in it until then. Somehow, I managed to trudge my way through without getting one of my water shoes sucked away into a different dimension. When I finally reached the first gravel bar, I was instantly rewarded with the nicest Ptychodus tooth (E) I have found yet. Scattered around the bar were tons of flakes and a couple of larger worked pieces (G, I) that were unfamiliar to me. Before moving on, I also stumbled upon what would've been the largest point I'd ever found (H). Unfortunately, it was pretty banged up. The previous rain wasn't that big in terms of flooding, so I spent the most time scouring the gravel still under water as I reasoned that the stuff on dry land was less likely to have been moved around in the storm. It was during this moment that I found my first mosasaur vertebra of the day (A). This one was exciting to me as I personally thought it very much resembled the verts that famously come out of the NSR's Ozan formation. Within a couple feet of it I found another half piece of mosasaur vertebra (B). With the close association of these two bones, I went into a bit of a frenzy. Nothing else came up, but I knew that there was a massive exposure just up ahead so I hurried on. Along the way I ran into a fragment of the smallest point I've come across (F). At its size, I wonder if the original piece would've been a true arrowhead. Once I reached the main exposure, I immediately got to probing around. I came across two more pieces of bone that I believe are both belonging to mosasaurs (C, D). They have bony structures, but they are also pretty beat up and may have come from a different formation in comparison to the other two verts I collected. With the day winding down I picked up a nice big Exogyra ponderosa for my dad's friend as well as a couple of preforms. I tried to look around in the exposure for any hints of mosasaur, but that shale is extremely difficult to get through. All in all, it was a great success. I think I've found my new go-to spot! With the addition of potentially 4 new mosasaur verts, that's a 400% increase in my total mosi collection! P.S. Does anyone else get "Tetris Syndrome" after scanning gravel bars for way too long? For hours after the trip, I literally could not stop seeing gravel and chert flakes every time I closed my eyes. An overview of the finds: Closeups for ID: A: First mosasaur vert of the day. To me, it strongly resembles those found in the NSR's Ozan formation. This one was covered in a clay-like matrix. B: The second vert of the day. Seems to be broken in half and from the same formation as A. Appears to have pyritization on some parts of it. C: Third vert which I believe is mosasaur. This one is beat up and seems to be of differing material from A and B. Could it be from the Austin Chalk which is present farther up the creek? D: The last "vert" of the day. This one I am least confident about. It appears to have a bony texture, but is very worn and has a confusing shape. It seems closer to C than A or B, but it also feels very distinct in it of itself. What do you guys think? I suppose it could be something else entirely! E: A nicely preserved Ptychodus tooth. I'm thinking anonymous or mammillaris, but my ID skills are pretty lackluster. F: "True" arrowhead fragment? G: Strange artifact. The angle seems too wide to be a point. I think it's too thin to be an adze. Obviously missing a huge chunk from that fresh curved break. What do you guys think? H: Fragment of a large point I: Another strange fragment. I think it may be an adze since it's a bit more robust. Fresh break on one edge. Let me know if you want any more close-ups. Thanks for reading!

I have a few vertebrae I was hoping to get identified. These are 3 that I don't have any others that are alike. I tried to search online and the oval shaped one looks like possibly a Pachy but wasn't sure. These were all found on the Judith River Formation Montana, Hill County. first 4 is the one that I thought was Pachy, 2nd 4 I am not sure, 3rd 4 might be Hadrosaur?

I found this rock in Austin, TX in Waller Creek next to an exposed outcrop of the Maastrichtian (Late Cretaceous) Austin Chalk. I’m wondering if it’s a mosasaur vertebra or humerus? Several mosasaurs have been found in creeks nearby, and the wavy pattern in the rock reminds me of fossilized bone. I’ve included three photos of the rock that I found in Austin, and a photo from Otero et al. (2016) of a Maastrichtian mosasaur right humerus (scale bar = 50 mm) that looks similar.

Hi everyone! I’m an amateur fossil collector who wants to collect and learn more about fossils and hope to learn more through this forum. Growing up I’ve always been fascinated by dinosaurs and sharks in particular. Today I went to a fossil show and found a vertebra that I found particularly fascinating. I bought it not knowing exactly what it was so I can chase the thrill of learning what it is and why. The man I had purchased it from had said it was from a spinosaurus. However, I’m skeptical because he was also marketing a tooth as an allosaurus tooth. He was honest man and had told me that he wasn’t exactly sure what kind of tooth it was. Later, I found out the tooth in fact belonged to a carcharodontosaurus based on the matrix. Luckily I didn’t spend money on what was thought to be an allosaurus tooth. Nor did I spend too much on the vertebra. Now I don’t have a lot of information to go off of. I’m not quite sure where exactly the vertebra came from nor do I know how the gentleman came to own it. All I do have are the photos that I took of it. Judging from the looks of it, it does seem to have come from Morocco based on the color and other specimens I have seen. I also tried to study the skeleton of a spinosaur to see if I could ID it using reference photos. It’s difficult to tell but if it did come from a spinosaur, I’m thinking it’s part of the neck. Anyways, if I could get some help that would be great! Bonus points if you could tell me which part of the animal it came from.

From Madagascar Probably Mesozoic Why is this fossil lying on its back .looks like a parrot's beak. ---------------------------------- These are some of the details that prove it's a fossil It's a very damaged fossil It preserved conical foramina, and preserved neural crest vertebrae fossils are rare in Madagascar So what kind of animal is this? Detail the rupture above the neural crest is seen to form a square inconsistency The fractures on the spine have detailed bone patterns Thank you for your answer. --------------------------------- Thank you for your insights. I've seen many kinds of vertebrae from Madagascar, but this one is very special, very strange. But I also want to ask: why is it in this form? Like a lie? As I've drawn it: the red is a separate spine, the yellow is another spine; The blue one is the nerve, why is it so combined,? what range of animals is it?

Greetings again Thisis a second vertebra also found at the Lee Creek Mine (aka Aurora) in Yorktown spoils. It is 50mm in length, rather porous and very light. I was thinking bird, but thought I'd get some other opinions. Any ID suggestions? The photos in order are: "bottom", "top", "side", end 1 and end 2

Hi all, it's me again! for my first expedition of the year, I decided to go to big brook to try my hand collecting there. had quite the adventure, found some neat things. but there are a handful of oddity's that I am unsure. in my research that ive done over the day I have a couple ideas, but any confirmation from experts is always appreciated. first one up is this weird thing. I'm not sure what this is although it's no concretion these ones are also strange, but I have some ideas on a few of them. top two are probably vertebrae fragments, but I have no clue what they are from. bottom left is a total mystery, but I think that the shark tooth in the right is possibly a Hybodont tooth. I say this because of all the research I've done both on this forum and the Big brook website. it is the only one that matches the profile. more views below @The Jersey Devil @Rockwood any ideas?

I was able to obtain a couple of fossils found on the western coast line of France. The first one is presumably a piece of paddle bone from the upper tithonian, found between Wimereux and Cap de la Crèche. It measures about 220 x 160 x 65mm. Very heavy. The second is a vertebra found between Cap d'Alprech and Equihen (Tithonian). Measuring about 80 x 65 x 35mm. Could these be pliosaur or rather plesiosaur fossils? I'm sure they are too worn to identify better than sp.? Thanx for notes!

I wonder if the baby shark song made outside the US, it's been stuck in my head since last night when I found the smaller of the 2 vertebra. Amazing I even spotted it, pretty sure the larger one is shark? Can anyone tell if tiny one is fish or shark? I'm trying to picture something so small, which shark could have babies so small? Could some shark vertebra be from babies still in egg sac? These were found in Eagle Ford, Cretaceous, the dark ruler is in mm.

I had found this vertebra in the box of matrix I'd gotten for my birthday. I think that it might be either a crocodile or a Pachycephalosaurus caudal vertebra, I was hoping that you guys might be able to identify it. It was found in the Lance formation of Weston County, Wyoming. Here are the pictures. Scale is in millimeters. Thanks for any help!

Myrtle Beach fossil - vertebra part maybe? (EDITED TO ADD PHOTOS)
PSchleis posted a topic in Fossil ID
Found on Myrtle Beach, Jan 18, 2022. Never saw this one before. Bottom is concave with a small protruding tip at the top (third picture) Top is rounded, coming to a peak in the middle. The top two pictures make this look almost like a steinkern but it isn't, as you can see from third image. Thank you!- 1 reply
