The Arkansaurus Dinosaur is Officially Official

Thursday, March 22, 2018

The Arkansas legislature resolved last year that Arkansaurus Fridayi was the state's official dinosaur and that was good. But now the Journal of Vertebrate Paleontology has announced the newly recognized creature and that is really official.

Arkansaurus (meaning "Arkansas lizard") is an extinct genus of ornithomimid theropod dinosaur. Arkasaurus fridayi, the type and only species, was declared the official Arkansas state dinosaur in 2017. The dinosaur was discovered in Lockesburg, Arkansas, and was a bipedal ornithomimosaur dinosaur. Its nearest relative is the ornithomimosaur Nedcolbertia. It is named for the state of Arkansas and its discoverer J.B. Friday, who found the dinosaur's fossilized foot on his farm in 1972. It is the only dinosaur fossil currently described from Arkansas. The fossil was officially described in 2018 by paleontologists ReBecca Hunt-Foster and James Quinn in the Journal of Vertebrate Paleontology.

Arkansaurus fridayi lived during the Albian and Aptian stages of the Early Cretaceous.
