What kind of Cretaceous Vertebra is this?

Recommended Posts

Need help with vertebra- I found it protruding from the Cretaceous mud at a creek in AL Saturday.  I was very excited!

 

It is about 1.75" wide at the longest, and 1" tall.

 

So, what do I have here?

Probably shark, but could be other large fish. Bring it by next time you're in town and I'll clean it up for you. Nice find. -- George

I'm leaning more towards large fish on this one.

Certainly looks fish imo....reminds me of a Concavotectum vertebra (below) but could also be shark

I am not hugely familiar with shark verts, but aren't they, in general, more flat.  I am going with random non-shark fish on this one. 

 

edit: or maybe a ray.  their verts are more robust, I think.

I think a none cartilaginous fish that is large.
Could be a funky shark.

I would guess something similar to Xiphactinus.

I would say Xiphactinus too.  I was looking at the replies and in the collage that Al Dente posted, the upper right and lower left corner pics are an xiphactinus audax that I collected at the NSR here in Dallas, before and after clean up. :)

 

Most of the shark verts around here are thinner and do not have as much structure as yours.

Okay, I will be the odd man out. Since you found it in Alabama and their fossils are common in your area, I'm going with mosasaur vertebrae.

Sorry Mikeymig, but mosasaur are concave on one end, and convex on the other. So it is not mosasaur.  Plesiosaur is concave on both ends, but this is a good example of X-fish.

When I found it I thought it was mosasaur too... too bad!  Mosasaur is my favorite prehistoric critter.
