2.8" Fossil Tortoise (Stylemys) Shell - Nebraska

This is a small, 2.8" long shell (carapace and plastron) of an Oligocene-aged tortoise (Stylemys nebrascensis) from the Brule Formation of Nebraska.

It comes with an acrylic display stand.

About half of the marginal scutes around the periphery have been restored. There is also restoration to the carapace and plastron, making up approximately 30% of this specimen.

Stylemys ("pillar turtle") is the first fossil genus of dry land tortoise discovered in the United States. They lived in temperate to subtropical areas of North America, Europe, and Asia.

These extinct tortoises had primitive jaw muscles, unlike today's tortoises that 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.
