5.3" Oligocene Fossil Tortoise (Stylemys) - South Dakota

This is a 5.3" long, Oligocene aged fossil tortoise (Stylemys nebrascensis) from the White River Formation in the Badlands of South Dakota. It has some crushing on one side, which most fossil turtles do. Total restoration is about 20% of the shell.

Stylemys ("pillar turtle") is the first fossil genus of dry land tortoise discovered in the United States. The genus lived in temperate to subtropical areas of North America, Europe, and Asia
These extinct tortoises had primitive jaw muscles, unlike today's tortoises, which also display the os transiliens bone, and would have been herbivorous. While Stylemys species did exhibit the same neck structure as modern tortoises, the forelimbs weren't ideal for burrowing.
