diginupbones Posted September 20, 2022 Share Posted September 20, 2022 My best guess is rodent. Hoping one of the experts can narrow down a bit.North central Nebraska. Miocene Thanks Link to comment Share on other sites More sharing options...

Harry Pristis Posted September 20, 2022 Share Posted September 20, 2022 Age by tooth wear? . . . No, but deer usually don't live long lives. 1 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...

Very true, I guess I wasn’t thinking that way. You don’t see many whitetails around here even today that make it more than 4 or 5 years.

diginupbones Posted October 4, 2022 Author Share Posted October 4, 2022 Here’s a comparison to a modern adult Whitetail deer. i’m still amazed by the size difference. Link to comment Share on other sites More sharing options...
siteseer Posted October 4, 2022 Share Posted October 4, 2022 What formation was the little jaw found in? Do you know how old it is? That jaw might be too old to be from a deer since the earliest occurrence of deer in North America might be the latest Miocene Montbrook site in Florida. @fossillarry Link to comment Share on other sites More sharing options...

Mahnmut Posted October 5, 2022 Share Posted October 5, 2022 (edited) Hi Diginupbones, looking at your size comparison, the fossil looks to be about one to two thirds the size of the recent bone, depending on which tooth exactly we are looking at. Perhaps a juvenile? But quite hefty for a rodent. (I did think about rats, mice, squirrels when I wrote this, not beavers and capybaras obviously, we do not get these here) Best Regards, J Edited October 5, 2022 by Mahnmut second thought Try to learn something about everything and everything about something Thomas Henry Huxley Link to comment Share on other sites More sharing options...
fossillarry Posted October 13, 2022 Share Posted October 13, 2022 The specimen is a right lower jaw of a little antilocaprid. It is Barstovian or Clarendonian in age. The teeth are well worn but were certainly low crowned when unworn. This puts this specimen in the subfamily merycodontinae. these small antilocaprids had horn cores that looked like antlers that appear not have keratinous sheaths,unlike the other subfamily antilocaprinae, That have both sheathed and unsheathed horn cores and were generally lager. The teeth are a little small to be a dromomerycid,cervoid like ruminants that also had bony unsheathed horn cores. Lastly the specimen is not from a blastomercid,small hornless deer like artiodactyls because their lower p4 is more complex then is found in this fossil. There are several antilocaprid genera that could be represented by this specimen but I am not versed enough in this group to try and ID this fossil. , 4 Link to comment Share on other sites More sharing options...
