RCFossils Posted March 26, 2020 Share Posted March 26, 2020 I have had this interesting skull for many years and was hoping someone might be able to narrow down what it is. I do not have any collection information as the person who found it is deceased. I know it is from the White River/ Brule formation. My best guess is some type of Beardog Daphoneus? Any help would be appreciated. 1 Link to comment Share on other sites More sharing options...
caterpillar Posted March 26, 2020 Share Posted March 26, 2020 Hyaenodon? 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
ParkerPaleo Posted March 26, 2020 Share Posted March 26, 2020 Looks like Hyaenodon to me. Hyaenodon crucians (sp?) on top. Daphoenus vetus (Bear Dog) on bottom If you look at the carnassials, you will notice Hyaenodon has a very flat bladed shearing tooth, and actually uses multiple teeth (M1-M2) in a row to make a very large shearing surface. The bear dog on the other hand, has a triangluar carnassial (P4) followed by 3 crushing teeth (M1-M3) after. Let me know if better pictures are needed. 3 Link to comment Share on other sites More sharing options...
mikeymig Posted March 26, 2020 Share Posted March 26, 2020 Looks like Daphoenus to me. Ive had both a complete Bear Dog and Hyaenodon skulls in my collection and have handled others but Im far from an expert. This skull is slender with smaller teeth when compared to a creodont. Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...

caterpillar Posted March 26, 2020 Share Posted March 26, 2020 I confirm Hyaenodon. The molars are carateristics http://www.paleotheque.fr Link to comment Share on other sites More sharing options...

RCFossils Posted March 26, 2020 Author Share Posted March 26, 2020 Thanks Is there any way to narrow it down to the species level? Link to comment Share on other sites More sharing options...
jpc Posted March 26, 2020 Share Posted March 26, 2020 species of Hyaenodon are basiclly bsed on size. This one is not huge, I would guess H. montanus. This is only a guess. 1 Link to comment Share on other sites More sharing options...
