GarethGP Posted May 18, 2022 Share Posted May 18, 2022 I was recently given a mandible by a retiring paleontologist that I've been prepping. It was buried deeply in matrix. He had recorded it in his records as merycoidodon sp. not knowing what species of merycoidodon it is. Does anyone know if we can tell based on size alone? Here are some pics.

Randyw Posted May 18, 2022 Share Posted May 18, 2022 (edited) Thats a lower front of a jaw… how wide is it from left to right? i suspect its a culbertsoni… its not right for a gracilis. Edited May 18, 2022 by Randyw Link to comment Share on other sites More sharing options...
GarethGP Posted May 18, 2022 Author Share Posted May 18, 2022 It's about 2.5 inches long and about 1.5 inches wide. It really is tiny which is why I was hesitant to say Culbertsoni Link to comment Share on other sites More sharing options...
Randyw Posted May 18, 2022 Share Posted May 18, 2022 (edited) The perfect size! I’d go with about 85%-90% certanty with culbertsoni the same part on the one pictured in the center measures the same.. the lower inscisor on a gracilis is much more robust then the one on yours.
