megaholic Posted August 11, 2014 Share Posted August 11, 2014 Since nobody is out digging bone valley due to the high water I decided I should go yesterday. Had a great day. (as you can see below) I don't want this to turn into a show and tell, so I will just say this came from bone valley Fla yesterday, and I would like some help with the ID.The large carnassial is 12 X 25 X 13mm crown height. The small tooth is 17 X 9 X 9mm. The jaw bone averages 20mm wide along the area of the teeth. Sadly it is broken off right at the foramen for the large canine, other wise it would have truly been a prize find. My suspicion is that it is jaguar. Too robust for the panther, and too small to be lion. (P. atrox)What do you think? Should I have stayed home? "A man who asks is a fool for five minutes. A man who never asks is a fool for life".

RichW9090 Posted August 11, 2014 Share Posted August 11, 2014 What fauna is this from in the Bone Valley, or do you not know? If it is the classic Palmetto Fauna, it won't be a jaguar - no jaguar from the Late Hemphillian. Rhizosmilodon fitae, recently described from that fauna, is jaguar sized, but is a Smilodontine. The length of m1 ranges from 21.5 to 23 mm. so yours is a bit larger than the known sample. Also from the same fauna is Machairodus catacopsis which is larger than Rhizosmilodon. Machairodus catacopsis lower m1 rangs from 32.0 to 35.6 mm in the sample from the Coffee Ranch in Texas, so it is appreciably larger than your specimen. The plural of "anecdote" is not "evidence".

RichW9090 Posted August 11, 2014 Share Posted August 11, 2014 Harry, if it is Pleistocene, that is a possibility. It is not a possibility if it is from the Palmetto. Still waiting for Megaholic to say if he knows what the age is. The plural of "anecdote" is not "evidence". Link to comment Share on other sites More sharing options...
Paleoworld-101 Posted August 11, 2014 Share Posted August 11, 2014 What a fantastic find! Fragment or not, carnivore material like this is very uncommon and the teeth look pristine. You should be very happy with this one. "In Africa, one can't help becoming caught up in the spine-chilling excitement of the hunt.

megaholic Posted August 11, 2014 Author Share Posted August 11, 2014 Thanks to all for your comments and help. In reply to Rich, I do believe it to be Pleistocene.
