酷東西

趣味知識

Elmisaurus had a fused tarsometatarsus, meaning its ankle and foot bones were joined together like in modern birds.1 2

Its name comes from the Mongolian word 'elmyi' meaning 'foot sole', because the first fossil found was a foot bone.1

Elmisaurus lived about 70 million years ago, during the Late Cretaceous period.1

Some scientists think Elmisaurus might be the same animal as Nomingia, another dinosaur from the same time and place.4 1

Elmisaurus was a caenagnathid, a group of dinosaurs that looked like birds and had toothless beaks.1

The first Elmisaurus fossils were found by a Polish-Mongolian expedition in 1970.1

迷思破解王

迷思： Elmisaurus was a bird because its foot bones were fused.

真相： Elmisaurus was a dinosaur, not a bird. The fused foot bone is a feature that dinosaurs and birds share, but it does not make it a bird.2
