Up for sale is an INCREDIBLE RARE and HIGH QUALITY primitive bear Indarctos sp. lower teeth/molar from Miocene of Linxia, Gansu province, NW China! Indarctos is an extinct genus of bear, endemic to North America, Europe and Asia during the Miocene. It was present from ~11.1 to 5.3 Ma, existing for approximately 6.2 million years. Indarctos is known from several species spread widely across Eurasia, North America, and North Africa, however, most of them are known from fragmentary remains which leaves us with insufficient knowledge of the anatomy, lifestyle, taxonomy and paleoecology of some species. These species are usually established based on poor remains, where the presence of sexual dimorphism, paleo-geographical variation and individual variation is not taken into account, resulting in a number of species whose taxonomic validity is doubted. The animal was the ancestor of modern giant panda in China.  The teeth is measured around 5.1 cm/2.007 inches in length, which preserved with incredible enamel details and coloration!!!
