About Athenar
Athenar is an extinct genus of dicraeosaurid sauropod dinosaur from the Late Jurassic of Utah, United States. The genus contains a single species, Athenar bermani, which was described by John Whitlock and colleagues in 2025 based on the holotype specimen CM 26552: a braincase and skull roof previously ascribed to the genus Diplodocus. The specimen was found in rocks belonging to the Morrison Formation at the Carnegie Quarry at Dinosaur National Monument.
Athenar existed during the Tithonian age of the Late Jurassic, and would have lived alongside other dinosaurs such as the carnivorous Allosaurus and the herbivorous Stegosaurus, Diplodocus and Camptosaurus.
