👉 Pristurus is a genus of extinct mammals that lived during the Late Cretaceous period in North America. They are known for their unique skull morphology, with flattened bones and a long, curved neck. Pristurids were herbivores and had a diet primarily consisting of plants, fruits, and small animals. Their teeth were adapted to grinding tough plant material into a fine powder that could be eaten by the primate-like predators they preyed on.
