TX Cretaceous Aguja Formation dentary ID

[JamieLynn]

Howdy all! I have this little dentary plate that I am uncertain as to ID. It is from the Aguja formation from West Texas, Brewster County. It is aprox 1/8 inch. I have looked in all the papers I have and can't find any images that match it.  It doesn't seem to match up with the two salamanders that are found in the Aguja, but it definitely seems to be an amphibian tooth plate I think. Any thoughts? @ThePhysicist tagging you since you also do lots of micro Aguja stuff....

the second photo looks kind of fishy with what looks like whole surface of possible teeth.  Mystery Aguja micros should also be compared to any of the other late Cret formations in the American west.

I think it’s bony fish.

Could it be a frog?

Not frog, note the single tooth row with pleurodont attachment in the above diagram. As the others mentioned, the jaw in question is a bony fish, very similar to those of teleosts I've found in Hell Creek.

makes sense - I know that reddish brown almost translucent coloration tends to be fishy. Thanks y'all!
