Name: “Arkansaurus fridayi”

Name Meaning: Arkansas Reptile

First Mentioned: 1983

Mentioned By: Sattler

Classification: Dinosauria, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Ornithomimosauria

“Arkansaurus” is an as-yet undescribed theropod from the Trinity Group in Arkansas, dating to between the Aptian and Albian ages of the Early Cretaceous, around 113 million years ago. Based upon fragmentary remains of the feet, vertebrae unassociated with this specimen have been said to belong to it. Dinosaurs aren’t very well known from Arkansas, and the classification of Arkansaurus is up for debate; until it is fully described, the jury is still out. It is thought to be an Ornithomimosaur, but it is far too early in the fossil record to be a well derived one, such as Ornithomimus. It could, alternatively, be a basal Coelurosaur.
