Trimerorhachis insignis

[Billy_Rees]

Hi,

 

I recently bought this online and it was listed as a Trimerorhachis Insignis tooth from Jefferson County, Oklahoma.

 

After comparing it with other images I think this could be a claw and not a tooth, but I'm not 100% certain... Could anyone please confirm if it is?

 

Thanks, Billly.

Welcome to TFF!

It is a tooth, not s clsw.

I can not help any further with ID, but others will be able to.

What size is what we are looking at?

Eryops maybe?

Definitely a tooth, but I'm not convinced it is Trimerorhachis. Can you post a photo of the place where the tooth broke off from the jaw?

Troodon, the size of it is about 3-4mm in length...

I dont think its Trimerorhachis their teeth dont appear to have cutting edges and this one seems to have them but the photos are not clear.  Pretty small.  I would also like to see a photo looking into the base

This is the best I can get...

At least some trimerorhachids do show cutting edges on some of the teeth, primarily the palatal fangs. So it's possible. I'm not seeing consipicuous labyrinthine infolding though so I don't know. It could also belong to a handful of other animals with similar dentition, but realistically I don't think you're going to have an easy time making a confident determination. Part of me even wonders if maybe this is some sort of fish tooth.
