An uncommon species sloth tooth, this complete molar with root comes from the prehistoric extinct giant ground sloth Megalonyx leptostomus. It seems that this variety of Megalonyx is found in less abundance in the fossil record than Megalonyx jeffersoni as we have been able to locate far more molar teeth of M. jeffersoni compared to M. leptostomus. This fossil tooth happens to be the first M. leptostomus molar we have offered. This molar is a top-grade example with intact, distinct and naturally lustrous black enamel over a black hollow root. Chewing surface and cusp are complete and undamaged with original chewing surface facets.
