This piece of turtle plastron was identified by Dr. Weems (an in hand look) as the sea turtle Carolinochelys wilsoni. I had been trying to I.D. it for a while before I was able to get it into his hands. It is about 1/4 of the plastron and this turtle is thought to possibly be the extinct ancestor of the modern loggerhead turtle (Caretta caretta). C. wilsoni is the only species in the genus.

Title says it all really. Can anybody help? @abyssunder @doushantuo @Fruitbat Thanks! -
I have no information on this other than it was found in a fossiliferous marine deposit. Any help is appreciated.

Hello everyone, I found this in a Cretaceous deposit in West Tennessee. I am not sure what critter it comes from. I haven't had the time to really clean it up, so it had some matrix on it still. The sure contains marine reptiles, shark, and fish remains, and occasionally terrestrial material. Please let me know what you think and if you need more pictures. My thumb is about 3cm wide.

About 20 years ago I bought this bone for $20 at a garage sale in the suburbs of Chicago. The woman did not know where her father had found it. Around that same time I showed it to Paleontologist Paul Sereno who was talking at a nearby library and he stated he believes it to be reptile. Just looking to see what other members think. @Troodon

I bought this vertebra a while back from our favourite auction site. Initially I bought it just because it looked like a nice vertebra, and I didn't think much of it. But when I had the real fossil in my hands I noticed that it's quite bizarre. I've never seen anything like it. So far everyone I've asked was stumped as well (though some suggested it might be croc). So I was wondering if someone here maybe had an idea. @Troodon maybe? It's a fairly nice centrum of a caudal vertebra, as the bottom does show some worn articulation surfaces for a chevron. And even though the neural arch is mostly missing, there doesn't seem to be an attachment for a lateral process. So I'm guessing it's pretty far down the tail of the animal. Though not as far down the tail since there is a chevron attachment. Now, there are mainly two weird aspects this vertebra has. For a caudal vertebra, the neural canal is really wide. The neural canal is also excavated a little into the centrum so that both the front and back of the centrum that gives it sort of "ears" on the top of the articulation surface. Then there is a kind of pinched area on the sides of the centrum. Looking at the sides of the centrum, the bottom middle is a lot wider than in the area dead centre. Here there the centrum is laterally pinched, making this area as thin as the neural canal is wide. So the centrum is maybe a centimeter thick in this area. Then immediately above it where a subtle shadow can be seen just below where the neural arch starts there is a wide horizontal bulge, making it the widest part of the vertebra right above the thinnest part. Any ideas?

Hello, I recently saw this tooth online. It's from the middle triassic layers (upperst Muschelkalk ) of Würzburg in Germany. I only think it's labeled incorrectly? What do you think? Is this a real tooth and what determination would you give to it? It measures 7 mm

I found this teeth in a marine sedimentary sandstone (Cretaceous.Palaeocene) and I don't know what is it.

Hi all, I recently found this on a trip to the Jurassic Coast at Dorset and have been intrigued by this find, i'm not an expert on fossil identification and was wondering if there was anything significant about this fossil. it strikes me as being either fossilised wood or an infilled burrow of some kind, however the shine, shape and downward strikes are leaving me somewhat puzzled. i would be grateful for all your potential ideas as to what this could be.

I went out exploring for possible fossils, and found a lot of what appear to be teeth, vertebrae, and assorted bones. Any further help with identification of these interesting artifacts would be greatly appreciated as I'm new to this fascinating field.

Distal caudal vertebra of a Spinosaur. This is from the very end of the tail. It's position is likely close to vertebra 40. The neural canal is quite wide and the centrum is laterally pinched in the middle.

Are these Claudiosaurus' real?
bgreenstone posted a topic in Is It Real? How to Recognize Fossil Fabrications
Last night I was contacted by a person on Facebook (red flag #1) who claims to have 7 Claudiosaurus fossils from Madagascar that he wants to sell me. While I would love to have these, I am of course very skeptical of their authenticity. Several of them consist of both the positive and negative plate which is a plus. When I asked how much he wanted for them his reply was "make me an offer" (red flag #2). So, can anyone tell from these photos he sent if these are real or fake? Any suggestions how I should proceed with him? I think he is in Mauritius (red flag #3) He says they're around 30cm / 1ft. in size. -Brian.thumb.jpg.210960463f3f283e6c1096238a1845a9.jpg)

Hey everyone, I found this vert today at ramanessin brook. This site has mostly cretaceous marine fossils but sometimes dinosaur material is found. This vert is very heavy and solid. I'm thinking it's plesiosaur but I'm not 100 percent sure. There is one large hole on the bottom of the vert. One cool thing about this specimen is that there is a bite mark that can be seen in the last picture. I'd love to hear what you all think this is. Thanks!

Reptilian fossil - Real or fake?
Aurelius posted a topic in Is It Real? How to Recognize Fossil Fabrications
Does anybody have any opinions about this? I don't like the look of it at all - where the bone has chipped away, there's red stuff underneath (glue?). This doesn't look like the usual Chinese fakes you see on eBay. This is the only photo available.

We've all laughed before at the nodules/concretions sold as eggs on popular auction sites, either by the ignorant or deceitful. However, most of the things I've seen advertised previously have been at least moderately egg-shaped. Not so with these stunning examples, which tend more towards being rock-shaped. I can only imagine how valuable these ordinary rocks - the exceptional colour and beauty of which are plain to see - were to the native Americans. I think it is a reasonable conjecture that they kept their favourite ordinary rocks in some sort of display cabinet, or possibly locked away in some kind of safe, to negate the risk of theft. I can now only marvel that these beautiful ordinary rocks have survived intact, and were not made into grinding stones, carved into bows and arrows, thrown at buffalo, or used to prop up tables on uneven surfaces.

I was scrolling through eBay when I saw this specimen but I don't know whether it's real because I might consider getting it. It is a Discosauriscus.

Is this small aquatic reptile fossil real?
FosselDumbDumb posted a topic in Is It Real? How to Recognize Fossil Fabrications
I found this fossil for sale and it seems almost too good to be true. Any help determining if this is real or a lemon would be great. The extra information I have on it is: Triassic Period, Carnian.Xingyi, Guizhou, China. Keichousaurus hui Young.

Well I finally managed to prep my Plesi vert from Golden cap, Charmouth. The started so easy the matrix falling off them then I hit the pyrite, what a pest they turned out to be. Ended up pinging them a few times with the pen but happy with them.

Hello everyone, Last year I have found a fossil tooth, which I (at first) thought could be an interesting shark tooth fossil - since shark teeth are very abundant in this locality. It is just about 10 mm long, but as I looked at it later, I thought that it must be marine reptile fossil. At home I took my micro-camera and took some detailed photos with some small maginification. Then I was sure it is not a shark tooth. but something else. I have discussed this finding with Daniel Madzia and his answer was that it possibly belongs to Plesiosauria sp., Ichthyosaurus or Crocodylomorpha. He is teropod expert though and suggested me to ask someone who is into marine reptiles. Could you please help me with identification ? Thank you very much. Lenght: 10mm. Unevenly striated, slightly curved, cone-shaped. Circular cross-section. Age: upper jurassic, oxfordian Site: Brno Hády quarry (Moravia, Czech republic, central Europe)
