Athenar
Athenar was a long-necked plant-eater that lived about 150 million years ago. It is known only from a skull and braincase that sat in a museum drawer for decades before scientists realized it was a new dinosaur.12

Athenar was a dicraeosaurid, a group of sauropods with shorter necks and smaller bodies than giants like Diplodocus.2
The only known fossil of Athenar is a braincase and partial skull roof, collected in 1913 by Earl Douglass.1
For 65 years the skull was thought to belong to Diplodocus, but in 2025 scientists re-examined it and gave it its own name.1
Athenar lived alongside famous dinosaurs like Allosaurus, Stegosaurus, and Diplodocus in the Morrison Formation.2
The skull of Athenar has a unique 'tooth' in the suture between two bones of the braincase, a feature not seen in any other dicraeosaurid.1
Even though the skull is quite large, the bones were not fully fused, suggesting this animal was still a subadult when it died.1

?What did Athenar eat?
Athenar was a plant-eater, like other sauropods. It ate plants that grew in its Late Jurassic environment.2

?When did Athenar live?
Athenar lived about 150 million years ago, during the Tithonian age of the Late Jurassic period.2

- The fossil was dug up in 1913 by Earl Douglass at Dinosaur National Monument, Utah. It was first described in 1978 as a Diplodocus skull, but in 2025 John Whitlock and colleagues named it a new genus, Athenar bermani.12

- Scientists are not sure exactly how big Athenar was, because only its skull has been found. They also debate whether some other skulls from the Morrison Formation belong to dicraeosaurids like Athenar.1
