Short summary
Pig-nosed turtles are an enigmatic group of reptiles with an extensive fossil record across the globe. The group is known to have inhabited North America during the Eocene, about 55 to 40 million years ago, but information is still limited regarding the exact morphology of these turtles, as remains are few. Here we document the morphology of the only known skull of a North American pig-nosed turtle based on a fossil from the middle Eocene Washakie Formation of Sweetwater County, Wyoming, USA.
