Roby Posted September 8, 2020 Share Posted September 8, 2020 This June I went hunting the Oligocene White River formation in Wyoming and found two lower Canine jaws. I could us a little help in identifying them. I was thing the second one could be a bear dog. Its a juvenile with new eye teeth starting to erupt but the front of the jaw is missing. 5 Link to comment Share on other sites More sharing options...
PrehistoricWonders Posted September 8, 2020 Share Posted September 8, 2020 Not sure... but excellent prep!!! Link to comment Share on other sites More sharing options...
Harry Pristis Posted September 9, 2020 Share Posted September 9, 2020 I don't know what they are, but I don't think they are amphicyonids. The Miocene species, at least, have a stronger resemblance to canids. 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...
FossilsandScience Posted September 9, 2020 Share Posted September 9, 2020 Amazing prep! Their most likely either bear dog, Hyaenodon or Hysperocyon. This image below should help out with identification 3 Link to comment Share on other sites More sharing options...

PaleoNoel Posted September 9, 2020 Share Posted September 9, 2020 I remember seeing this one the night you found it, I said the same thing as @FossilsandScience. Perhaps @jpc or @fossillarry could help. Link to comment Share on other sites More sharing options...
jpc Posted September 9, 2020 Share Posted September 9, 2020 I wish I could help, but I don't rightly know.... not off the top of my head. Link to comment Share on other sites More sharing options...
Roby Posted September 9, 2020 Author Share Posted September 9, 2020 Thanks all. I currently don't have a good documentation source and searching the Internet has not always proven to be a very good source. Link to comment Share on other sites More sharing options...
jpc Posted September 9, 2020 Share Posted September 9, 2020 I have a copy of Jepsen and Scott at work. I can't remember if there are canines in there, but I will give it a look-see. Link to comment Share on other sites More sharing options...
siteseer Posted September 9, 2020 Share Posted September 9, 2020 I think the jaws are from Hyaenoodon. I think the other specimen is also Hyaenodon but a maxilla piece. I'll try to get a hold of Fossillarry. Jess Link to comment Share on other sites More sharing options...
fossillarry Posted September 12, 2020 Share Posted September 12, 2020 All the fossil jaws you have pictured are from a small species of Hyeanodon . The first photo is from a juvenile with deciduous(baby teeth)dp3-4 and permanent m1 in both jaws with a permanent incisor jest beginning to erupt. Second photo is also a juvenile Hyeanodon with the same teeth visible on the right side except the incisor. the third and fourth photos are also a small species of Hyeanodon . the third photo are right and left adult maxillae with canine to m3 on both sides. The fourth photo is also an adult Hyeanodon with right and left maxillae less well preserved. Did you collect these fossils in the Lusk area? I have collected in that part of Wyoming many times. Your specimen are exceptionally good for illustrating the upper dentition and lower deciduous dentition of this small species of Hyeanodon. Fantastic finds. 1 Link to comment Share on other sites More sharing options...
Roby Posted September 20, 2020 Author Share Posted September 20, 2020 Sorry but I don't remember the formation they came from I will have to ask the guides. It was about an hour south of New Castle Wyoming. Thanks very much in helping me identify these finds. Link to comment Share on other sites More sharing options...
