酷東西

趣味知識

Megapnosaurus was one of the first dinosaurs ever shown with feathers in pictures, even though no one has found actual feathers with its fossils.1

At least 30 Megapnosaurus skeletons were found together in Zimbabwe, which suggests they might have lived or hunted in groups.1

Its name changed over time: first it was called Syntarsus, but that name was already used for a beetle, so scientists gave it a new name in 2001.1

Megapnosaurus had an S-shaped neck and long hind legs that looked like the legs of a secretary bird.1

Its hands had four fingers, which is more than most later meat-eating dinosaurs had.1

Some scientists think Megapnosaurus might actually belong to the genus Coelophysis, but most recent studies say it is its own genus.1
