Arkansaurus is the only dinosaur fossil ever described from the state of Arkansas.1

Its foot bones show a greenstick fracture, which is the first time such a healed break has been found in a dinosaur fossil.1

The dinosaur was discovered in 1972 by Joe B. Friday on his farm, and it was named after him and the state.1

Arkansaurus was a basal ornithomimosaur, meaning it was an early relative of the ostrich-like dinosaurs, but not as advanced.1

It lived along the shoreline of a shallow sea that covered parts of North America during the Early Cretaceous.2

Scientists think Arkansaurus could run fast because its foot bones were long and slim, with three toes.2

Ho sibollwa: The foot bones were found in August 1972 by Joe B. Friday in a gravel pit near Lockesburg, Arkansas. Dr. James Harrison Quinn studied them and named the dinosaur Arkansaurus fridayi, but he died before publishing. The name was officially published in 2018 by paleontologists ReBecca Hunt-Foster and James Harrison Quinn.1
E sa ntse e phehwa kgang: Scientists are not sure exactly what Arkansaurus looked like because only foot bones have been found. Its appearance is guessed from related dinosaurs.2
