Id Needed - Found In Late Triassic Deposit Area In Argentina

[Sekhmet]

Hello all! I found this a few days ago while hiking in the Ischigualasto provincial park in San Juan province in Argentina.

I'm not even sure it's a fossil at all, but it was too heavy to be a bone, and it also felt (and sounded) like a rock.

I took a few pictures of it and its surroundings, marked the spot in my GPS and left it where I found it (It's illegal to collect fossils in this area) so I hope these pictures will be enough.

Thanks!

This is an upper Equus (horse) cheek tooth. It looks old.

Thanks! Do you think it's fossilized? It really felt very heavy, even for a tooth... it was more like marble or something like that. The only thing that made me think it's not a fossil was that it's very white.

It's really hard to say; teeth are pretty highly "mineralized" in composition to begin with.
