Haplocheirus
Haplocheirus was a small, speedy meat-eating dinosaur that lived in what is now China. It had a long, slender skull and lots of sharp teeth for catching small animals. Scientists think it was one of the earliest relatives of the weird, one-clawed alvarezsaur dinosaurs.1

Datu dibertigarriak
Haplocheirus had more teeth than most other meat-eating dinosaurs, with up to 74 teeth in its jaws.1
Its name means 'simple hand' because its hand bones were simpler than those of later relatives.1
The only known fossil of Haplocheirus is almost perfectly preserved in three dimensions, which is very rare for a Jurassic dinosaur.1
It was one of the largest early alvarezsauroids, but still only about as long as a small car.1
The fossil of Haplocheirus was found with the bones of a crocodile-like reptile lying next to it.1

Mitoa: Some people think Haplocheirus used its strong thumb to dig for insects, like an anteater.
Egia: Scientists are not sure. Its teeth and skull suggest it ate small vertebrates, not insects.1
