Merycoidodon sp.

Recommended Posts

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.

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.

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

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.
