North Sulphur River Jaw Sections

[JarrodB]

@KimTexan asked to see some of my jaw sections so here's a few from the North Sulphur River Texas. This is a nice mix of Xiphactinus and at least 2 species of Mosasaur.

This one is pretty impressive looking, quite a nice chunk. I had not seen this one before.

This one is cool with that big ol’ tooth sticking out.

This one below is my favorite though. It looks cool with the 2 tone colors and the teeth/roots in the sockets. What I find most interesting is that it looks like there are 2 rows of teeth. Maybe those are just the next generation getting ready to erupt. What are those holes on the top side?

I assume this is a mosasaur piece. I guess I don’t know anything about reptile teeth formation and generation.

Whatever the case it is a cool piece.

Thanks for posting.

Yes the large one is a Tylosaur jaw section with multiple replacement teeth erupting. I'm sure it has more complete teeth inside if I did a Xray on it.
