名字的意思： “horse dragon”1

吃：植物有喙的草食恐龍白堊紀早期

Hippodraco was a plant-eating dinosaur that lived during the Early Cretaceous period. Its long, low skull looked a bit like a horse's head, which is how it got its name. It was a small, speedy runner that munched on tough plants with its shield-shaped teeth.1

酷東西

趣味知識

Hippodraco's name comes from the Greek word 'hippos' (horse) and the Latin word 'draco' (dragon), because its skull is long and low like a horse's.1

The only known Hippodraco skeleton was discovered in 2004 by Andrew R. C. Milner at a site called Andrew's Site in Utah.1 3

Hippodraco had shield-shaped teeth, which is why its species name 'scutodens' means 'shield tooth'.1

This dinosaur was about 4.5 meters (15 feet) long, which is roughly the length of a small car.1

Scientists think the only Hippodraco fossil found might be from a young dinosaur, because its eye socket (orbit) is very large compared to the rest of its skull.1 3

Hippodraco lived about 139 to 134 million years ago, during the Valanginian stage of the Early Cretaceous.1
