Zaraapelta

Zaraapelta's skull was covered in bumpy armour plates called osteoderms, and it had an especially fancy pattern of bumps and grooves behind its eye.12

The horns on the back of its skull had a smooth ridge on top, which is different from any other ankylosaur.13

Scientists think the fancy skull ornaments might have been used to attract mates, like a peacock's tail feathers.2

Zaraapelta lived alongside two other ankylosaurs, Saichania and Tarchia, in the same desert.12

The only known fossil is a skull missing the snout tip, and it probably belonged to a young adult.1

The name Zaraapelta comes from the Mongolian word for hedgehog and the Greek word for small shield, because ankylosaurs looked prickly and armoured.12
