A distal caudal vertebra of a theropod dinosaur. This vertebra is quite similar to Masiakasaurus from Madagaskar. So I've labeled this as cf. Abelisauroidea. There have been some reports that there are Noasaurids in the Kem Kem beds, so that might be a more specific possible identification. However at the moment just not enough is known about the Kem Kem fauna.

This is a close up of the Caudal and anal fins. Note the preservation of bones. Paddlefish only have bones in their fins and skull, the rest of the body is composed mainly of cartilage. -
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?

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.

Dear members of the fossilforum, I recently acquired this caudal vertebra of Camptosaurus dispar. the fossil label is as follows: Camptosaurus dispar, caudal vertebra Upper Jurassic, Morrison Formation From channel deposit near Bone Cabin Quarry, Albany County, Wyoming. Found by employee of Quarry lease owners. The questions I have about this fossil are: - Does anyone know the name of this channel deposit? - Does this vertebra look like it came from the Brushy Basin Member or more like it came from the Salt Wash Member? Thanks in advance for your answers, Sander

Hi there, I bought a hadrosaur caudal vertebra online a while ago and I was wondering what genus/species it is? It is from Southeastern Utah - I'm not sure which formation, the seller didn't say. Just joined up and would appreciate any help or suggestions! Thank you!
