garyc Posted March 31, 2017 Share Posted March 31, 2017 Any ideas for what this jaw belongs to? Pleistocene river gravel from the Brazos in SE Texas. The teeth are either very worn, or the crowns have broken off. Thanks! Link to comment Share on other sites More sharing options...

garyc Posted April 2, 2017 Author Share Posted April 2, 2017 I also thought peccary at first, but the more I look at it I'm thinking bison. The teeth look like the crowns have worn down completely and then split at the bottom. I've never seen bison teeth wear down this much so I may be way off base. Anyone else?

Uncle Siphuncle Posted April 2, 2017 Share Posted April 2, 2017 Gary. A couple pics for comparison of both size and tooth morphology. Pleistocene Bison jaw I found a while back, and a mandible from an adult javelina Pecari tajacu (about 50 lbs live weight) that I shot years ago. I have read that Pleistocene peccaries were quite a bit larger than the extant collared peccary. I haven't studied tooth morphology of extant vs. extinct peccaries. Just FYI. Grüße, Daniel A.

Uncle Siphuncle Posted April 2, 2017 Share Posted April 2, 2017 You could always take a cow jaw to the bench grinder and see what you come up with! Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...
