Short summary
Baenids are a group of fossil turtles with a rich fossil record that spans from the Late Cretaceous (Campanian) to Eocene of North America. Only a few fossils are known that document the early evolution of the group. We here describe a new species of baenid, Lakotemys australodakotensis, from the Early Cretaceous (Berriasian to Valanginian) Lakota Formation of South Dakota, USA. Phylogenetic analysis suggests that this is the oldest known baenid turtle.
