Palaetherium crassum, jaw fragment
A jaw fragment from the lower right jaw of the ancient proto-horse Palaeotherium. It includes the last two molars and a piece of the third last molar. The cusps of the molars are crescent- or V-shaped and connected by enamel ridges. This pattern is called selenolophodont dentition. The molars are low-crowned, which indicates a leaf- and fruit-based diet. High-crowned molars, as we know them from modern horses, occured during the Miocene due to a habitat change from forest to steppe and the associated dietary switch to grasses.
The locality has been depleted, which is why jaw fragments with this rich dark brown coloration have become rare.
