Coryphodon teeth and jawbone and teeth from what? Large "primate primate

[john h dalton]

I went out the other day and found these three cool fossils. I know the two are from a coryphodon but the two teeth still in the jawbone I'm not so sure of. I have seen and found " monkey" teeth but these  are much larger then the small primates that once lived in wyoming or at least larger the  what I've found.  Anybody have another idea what they may be?? Thanks J.D.

Can we see a good in focus image of the chewing surfaces?

the loose teeth look very coryphodon-ish.  The jaw frag seems too worn out to ID .

Teah, I agree with Jpc.  That little jaw piece looks too bleached and powdery to allow any clear tooth characters to remain.

 

Yeah, the primates that lived along with Coryphodon were small.  It was a time before there were any monkeys.  Some of those primates would have looked more like lemurs and others like modern tarsiers.

The shot of the chewing surface is much too blurry.

The camera focused on your fingers.

Based on size of the jaw, and the shapes (outlines) of the teeth, I am going to guess the little one is a Hyracotherium.  The primates of this time period are much smaller still.
