gauza bikainak

Datu dibertigarriak

Homalocephale had a flat skull roof, unlike many other dome-headed dinosaurs that had a rounded dome.2

Its tail was wrapped in a basket-like network of tendons, which is why its species name calathocercos means 'basket tail'.2

Homalocephale is known from a nearly complete skeleton, including a full skull and most of the body.1

It lived about 72 to 68 million years ago, during the Late Cretaceous.1

This dinosaur was about 1.5 metres (5 feet) long, about the size of a large dog.1

Homalocephale had strong legs and could walk on two feet, but it was not a fast runner.2
