Something? From Ozan Formation

[BobWill]

This is from a North Sulphur River tributary in Fannin County Texas. It's Upper Cretaceous, Ozan Formation.

Essentially an oyster. I think if you google ostrea falcata you will be in the right neighborhood.

Thanks Rockwood. That gets added to the faunal list from here.

The material around the oyster looks somewhat coprolitic. If that's the case, it could be Globidens fecal matter.

Good point Kris. I wondered about all of the odd bits with the (now) obvious oyster shell. I should have taken it to the Dallas Paleo meeting Wednesday. We had a trace fossil show-and-tell / ice cream social instead of the usual speaker and I made it a point to avoid the coprolite cliché but this would have added an interesting twist. I just took some tracks, a crinoid stem with bite marks and an example of bioimmuration.
