garyc Posted October 23, 2019 Share Posted October 23, 2019 I found this today on the Brazos River in SE Texas. At first I thought it was a chunk of a vertebra. After washing some mud off I was surprised to see teeth with roots extending to the broken ends of a mandible. Based on the shape of the teeth I think it is a xenarthran, but which one???

garyc Posted October 23, 2019 Author Share Posted October 23, 2019 Thanks @JohnJ! I’m leaning toward Holmesina, but really need confirmation... @Harry Pristis @Uncle Siphuncle @PrehistoricFlorida Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted October 23, 2019 Share Posted October 23, 2019 I’m not familiar enough w Holmesina incisors to say much for certain, but here are a couple of my sloth jaws for comparison. Hard to find with any teeth remaining, so you made a good find. Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils." Link to comment Share on other sites More sharing options...

jcbshark Posted October 23, 2019 Share Posted October 23, 2019 i'm thinking sloth gary but let's see what others have to say... regardless that's an awesome find! Every once in a great while it's not just a big rock down there! Link to comment Share on other sites More sharing options...
Harry Pristis Posted October 23, 2019 Share Posted October 23, 2019 I believe that it is a mylodontid sloth symphysis. Mylodontids have caniniform front teeth which is what I think you see in the fossil. Family Mylodontidae includes Thinobadistes sp. (Late Miocene) and Glossotherium sp. and Paramylodon sp. (Late Pliocene to Pleistocene). 6 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
garyc Posted October 23, 2019 Author Share Posted October 23, 2019 Thanks @Uncle Siphuncle, @rand95 @jcbshark and @Harry Pristis. That is excellent information. A sloth jaw with teeth has been on my bucket list. Very exciting!! Link to comment Share on other sites More sharing options...

GallinaPinta Posted October 24, 2019 Share Posted October 24, 2019 Maybe if you look around the place you found it you can find other pieces from the same specimen. Great find! 1 Link to comment Share on other sites More sharing options...

Shellseeker Posted October 24, 2019 Share Posted October 24, 2019 Gary, WOW!!! And that from someone who has a couple of these. I am having trouble orientating that tooth. How long is it???

garyc Posted October 25, 2019 Author Share Posted October 25, 2019 @Shellseeker I think both of the teeth are broken flush with the jar line. The best measurement I can get is about 2 inches per tooth. It’s interesting that one tooth has a cavity that goes all the way through to the root Link to comment Share on other sites More sharing options...

PrehistoricFlorida Posted November 5, 2019 Share Posted November 5, 2019 Definitely a sloth symphysis. The shape of caniniforms reminds me more of Megalonychidae than Mylodontidae, though. 6 www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
