Croc Scute or Drum Plate?

Recommended Posts

PaleoNoel

Hey all. I'm wondering if this fossil I found at Green Mill Run, NC is a crocodilian scute or the dental plate of a drumfish as I believe either can be found at this location.

It's a tough call. The shape in the lower left is quite socket like though. That would tend to indicate tooth plate.

I agree with Al. It looks like a croc scute.

+1 for croc.

IMO the holes are not symetrical enough to be "teeth-sockets" in a fish mouth.

Scale-bar is missing...

Can we see the back of it? Might help with ID.

Sorry about that, the fossil is about 1.5 cm at its greatest width.

Definitely Croc osteoderm.

Thanks, that's what I was thinking based on the irregularity of the pattern compared to the drumfish plates I've seen.

Identical to croc scutes I find.

Thanks to everyone for their input, does anyone have an inkling as to what genus of crocodilian this could come from based on the locality?

The sculptor in me sees potential to form a good likeness of the original post from any of these.

That is a crocodylomorph osteoderm ("scute") fragment, and given the discovery location it is probably from either Thecachampsa [aka Gavialosuchus] carolinensis or Alligator mississippiensis.
