Miatria Posted May 16, 2017 Share Posted May 16, 2017 I am interested in a specific ID of this piece of rodent mandible. When I found it I immediately assumed it was mouse but then I decided maybe it is a bit too big for a mouse so I started studying small rodent dentition charts and was amazed at all the variations in the molars. Another hour in the internet rabbit hole (no pun intended). 7/8" in length (22mm), found in Florida's Peace River in a mix of Miocene and Pleistocene material.

Miatria Posted May 16, 2017 Author Share Posted May 16, 2017 Yes, I think it could be ondatra, muskrat. Someone sent me down that path. There was as suggestion of neofiber which could fit the small size. Zookeeperfossils.com Link to comment Share on other sites More sharing options...

doushantuo Posted May 22, 2017 Share Posted May 22, 2017 I think I might be able to help you out with small mammal literature. A lot of what i have is probably NOT in Fruitbat's library,BTW Link to comment Share on other sites More sharing options...
digit Posted May 24, 2017 Share Posted May 24, 2017 I do best with fossils from species that I've already found (and have had the opportunity to both see up close and been motivated to do some research). It looks a lot like one of the pieces I found in the Peace last December which turned out to be from the Round-tailed Muskrat, Neofiber alleni (aka Florida Water Rat). Have a look at my find for comparison: http://www.thefossilforum.com/index.php?/topic/70700-peace-river-again/&do=findComment&comment=743695 Here's a link to the FLMNH page for this species so you can get a look at more imagery and information: https://www.floridamuseum.ufl.edu/florida-vertebrate-fossils/species/neofiber-alleni/ Cheers. -Ken Link to comment Share on other sites More sharing options...
abyssunder Posted May 25, 2017 Share Posted May 25, 2017 If I put your specimen in mirror image and compare it with the specimen in question, the similarity between the two is very good. I think you are right with Neofiber alleni, Ken.

I'm much better at posing potentially correct identifications when it is something I've come across personally. Cheers. -Ken Link to comment Share on other sites More sharing options...
