Vert?


SoreBack

Recommended Posts

Hello Folks,

This came from the NJ Cretaceous this weekend and I was wondering if this could be a vertebra or is it wishful thinking and a concretion.

Thanks in Advance,

Steve

That's a vert alright. Maybe Whale? Hopefully others can help with a true ID.

Based on your other material, It's a shark or ray centrum. They can be tough to differentiate.

Nice.

It's hard to remember why you drained the swamp when your surrounded by alligators.

Aren't shark verts a perfect circle? This seems a bit oval to me. It could just be the angle of the pics though.

It's pretty worn. It still could be a shark vert. And I've even seen bony fish verts with this general shape. Still, I'd lean a bit toward non-shark chondrichthyan.

I have gotten shark verts from the Moroccan Cretaceous that have deformed into more of an oval shape, probably due to the pressure of the material over it in deposition.

I guess I should of said Chondrichthyes vertebral centrum.

This is a funkitized version of what you may have. I have learned that the distinction between ray and shark is difficult to determine so I'm going with Squali for mine. LOL

The other views. In hand of a paleontologist I've been told it is likely a shark vertebral centrum

The more I look at it, the more it looks like amiid. I will stick with not shark. :)

Shark verts can also be oval and they can be circular or oval with flat spots.

Vertebrae like this are regularly found in NJ late cretaceous marine deposits. Any non-marine material is exceedingly rare and these vertebrae are not. Ischyrhiza, Ischyodus, and a few batoids are common in the same layers.

Ok I give, could someone point out to me the reasons for fish and not Chondrichtheys?

It would help a lot

Thanks

Not sure I understand the question, Jeff. Can you rephrase?

Thanks carl, I am wondering how to discern between the two classes being discussed as an ID for Soreback's vertebrae post.

Amiid's (bowfin) are of the Class: Actinopterygil (ray finned fishes)

sharks and rays are of the Class: Chondrichthyes

What characteristics in the fossil would lead one to decide either way?

Some nice pictures of Amia vertebrae HERE , as well as some other cool things. :)

I can't claim to know them extremely well but I know they can be quite similar. I'm just always wary of snap IDs that call these things shark verts when there are a few other options. Of course, sharks are always the best choice because they are so common, but that doesn't prove they are shark verts. Just being cautious!

I'm trying figure out the difference between the two classes as related to vertebrae.

My proclamation of squali was more in jest than anything else.

I see the similarities and am wondering what the differences are

Thanks for any replies.
