Post Oak Creek Molar

I recently found what looks like a mammal molar while I was screening through some bulk sample material from Post Oak Creek in Sherman TX (Austin group). I usually just find marine teeth, verts, gastropods, brachiopods, etc.. But, then I found this little guy. The marks in the pictures are 1mm apart. Any ideas?

How cool is that!

I'll stay tuned in hopes that someone can ID it.

Hey G.

Did you show that thing to Wes at the DPS meeting Wednesday? I think he has some rodent teeth.

Not to Wes, but to several others. I'll just email him some pictures and ask. Thanks for the reminder.

My best guess:

Family MURIDAE

a sigmodontine rodent

cf. Sigmodon sp.

m3

I had to that up; according to Wikipedia, Sigmodon is the Cotton Rat genus.

Sigmodon = "S-tooth", the shape of the molar when viewing the occlusal surface.

I did some checking on the Sigmodon and it seems to fit. I took more pictures of the occlusal view and compared it against some of the drawings. Thanks for the assistance. I guess it's true that nice things come in small packages (if you consider a rat tooth nice - but I think it is pretty cool).
