garyc Posted April 8, 2021 Share Posted April 8, 2021 I found this recently on the Brazos River in southeast Texas. It has me stumped. Any ideas? @Harry Pristis @Shellseeker @fossilus @Lorne Ledger Link to comment Share on other sites More sharing options...

I have seen similar... a circular hole in red, a channel in blue... A hole in the sidewall, A channel on top..... I think it is part of a mandible....

garyc Posted April 8, 2021 Author Share Posted April 8, 2021 Thanks, Jack! If you look at my first pic on the left and my 3rd pic on the right, you can see there’s a circular impression, like a socket.... but not very deep. I’m trying to make this piece be part of a tortoise, but I can’t find any comparable pictures on line showing how limb bones articulate with the rest of the tortoise skeleton @Shellseeker Link to comment Share on other sites More sharing options...
Lorne Ledger Posted April 10, 2021 Share Posted April 10, 2021 hmmm, I think it is mammal - it almost looks like part of a giant sloth scapulae with the acromion ridge worn off. That is just a guess, but it would have to be from a pretty big animal I would think. Link to comment Share on other sites More sharing options...
fossilus Posted April 10, 2021 Share Posted April 10, 2021 Going off Shellseekers mandible idea, could it be a part of a proboscidean jaw? 1 Link to comment Share on other sites More sharing options...
