garyc Posted April 8 Share Posted April 8 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 post Share on other sites

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.... Link to post Share on other sites
garyc Posted April 8 Author Share Posted April 8 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 post Share on other sites
Lorne Ledger Posted Saturday at 12:42 PM Share Posted Saturday at 12:42 PM 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 post Share on other sites
fossilus Posted Saturday at 07:59 PM Share Posted Saturday at 07:59 PM Going off Shellseekers mandible idea, could it be a part of a proboscidean jaw? 1 Link to post Share on other sites
