Dimetrodon? Claw?

Recommended Posts

Familyroadtrip

Hi,
I’m considering buying this “dimetrodon claw” and was wondering if it is really a dimetrodon claw. It was found in waurika, Oklahoma, Ryan formation and is from the Permian. I’m not sure how big it is but it looks pretty small. TIA

@Bobby Rico I read that topic and I’m not sure whether it is a dimetrodon claw or not now.

It can be very tricky I think with a partial Juvenile  claw , but hold on there is some very knowledgeable members here that will help you out,

I think I’m gonna stay away from this one because I’m not sure if it’s a dimetrodon claw or not and there are plenty of other fossils. Thank you all for the replies!!!

Beautiful little Dimetrodon claw that has been bitten off at the joint. I find Dimetrodon claws quite frequently with the bites like this. 

Do you know what would cause Dimetrodon claws to be bitten off like that? It sounds painful! :fear:

You think it’s a dimetrodon claw? I’d love one, but it didn’t look like the ones in the picture.

I agree it does sound painful!

Perhaps they just chewed their toenails when nervous. 

I know I do. :D

A couple of observations.

Dimetrodon claw "E" in the illustration from the above post looks V shaped in the cross-section view.  The one your asking about does not if you look at the 4th photo. 

Also the claw in the illustration has a big curvature from the tip to the tubercle, yours does not.    Not sure if its positional or due to ontogeny

This is pretty cool - we have quite a few varieties of Dimetrodon claw that display the flat dorsal morphology and also the curved. It is both a species thing and ontogenetic thing.

Without a Doubt, Dimetrodon. Will try to get some photos of specimens up soon.

The damage to the base of he claw is likely due to incomplete ossification of the bone, rather than damage from feeding or scavenging. The base of the claw would have been mostly cartilaginous in juveniles; we see this in completely articulated hands of young animals.

I'll try to take some pics of our claws- wonderful tooth marks show scavenging

Also have some really monstrous claws from the grandis species that have been bitten in half- a few have some awesome healed breaks as well. We do see Xenacanthid tooth marks. Ddon bites are much easier to identify than amphibs, sharks pretty easy.

I'm sure there is some scavenging, I just don't think every claw shows it.
