garyc Posted June 13, 2018 Share Posted June 13, 2018 Found on the Brazos River in Texas in Pleistocene gravels. Any thoughts? Link to comment Share on other sites More sharing options...

I had actually considered a juvenile proboscidean astragalus, but it didn't seem quite right compared to a couple of larger astraguli in my collection. Sloth would be really cool! Let's see what others say. Link to comment Share on other sites More sharing options...
Shellseeker Posted June 13, 2018 Share Posted June 13, 2018 Hmmm, Probably way off base. Harry has an interesting response in this thread, http://www.thefossilforum.com/index.php?/topic/49369-astragalus/ My initial thought was Rhino, then I downsized to tapir, maybe peccary. Do you have those in the Brazos? At least it gives you some more options A good sized Rhino astragalus from the Pleistocene of Florida The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Maybe some of the diagnostic features have worn off of mine. I’m not quite able to see a match anywhere. I’ll try posting some more pictures in a little while and see if that helps.

fossilus Posted June 13, 2018 Share Posted June 13, 2018 This is a poor picture, but I still think it quite possibly sloth. Maybe not megalonyx, but there were several sloths found in texas. https://www.floridamuseum.ufl.edu/files/5714/7172/0582/Vol-12-No-5.PDF Link to comment Share on other sites More sharing options...
garyc Posted June 13, 2018 Author Share Posted June 13, 2018 Thanks fossilus, that’s a great resource. I do see similarities. I love sloth and have found several pieces of sloth around here that likely are megalonyx. Link to comment Share on other sites More sharing options...
fossilus Posted June 13, 2018 Share Posted June 13, 2018 Another suggestion. Google megalonyx astragalus photos. I think you will find several photos that look like yours. Not always the best way to make an ID but might give some confidence. Link to comment Share on other sites More sharing options...
