Sapient Stylemys

Stylemys ("Pillar turtle") is a genus of tortoise from the Eocene to Oligocene periods of North America, Europe, and Asia. It is the first fossil tortoise genus ever discovered in the United States. Unlike modern tortoises, Stylemys had weak jaw muscles and had forelimbs unsuitable for burrowing. Because of its weak jaws, it was a herbivorous species.
