趣味知識

The name Einiosaurus comes from the Blackfeet word for bison, because these dinosaurs may have lived in herds like bison do today.1

At least fifteen Einiosaurus individuals of different ages have been found together in two bonebeds. Scientists think they died in a drought or flood.1

The nasal horn of Einiosaurus curves forward over the nose, which is why its species name means 'with a forward-curving horn'.1

Einiosaurus had a pair of large, curved spikes sticking out from the back of its skull frill.1

All known Einiosaurus fossils are kept at the Museum of the Rockies in Bozeman, Montana.1

Einiosaurus lived in a warm, semiarid climate with a long dry season and a short wet season.1
