Baenidae
Extinct family of turtles
From Wikipedia, the free encyclopedia
Baenidae is an extinct family of paracryptodiran turtles known from the Early Cretaceous to the Eocene of North America.[1][2] The name of the type genus, Baena, appears to be of Native American origin, likely from the Arapaho be’enoo. They are primarily found in freshwater deposits, and are considered to be aquatic, with a largely generalist habit.[3]

Evolutionary history
During the Early Cretaceous they were found across North America however by the Late Cretaceous they are only found in Laramidia having disappeared from Appalachia. Most lineages survived the K-Pg Extinction, but the family was extinct by the latest Eocene.[3]
