酷東西

趣味知識

Oohkotokia had a median nasal plate on its snout, a smooth patch of bone that helped identify it.1

Its armour had a fine, pitted texture, unlike the rough bumps on some other ankylosaurs.1

The name Oohkotokia comes from the Blackfoot word for 'child' and 'stone', meaning 'child of the stone'.1

It lived at the same time as other ankylosaurs like Euoplocephalus and Scolosaurus, but in different layers of rock.1

This dinosaur was an ankylosaurine, a group of armoured dinosaurs with tail clubs.5
