酷東西

趣味知識

Parvicursor had a single large claw on each hand, which it may have used to tear open termite mounds or dig for food.1

Its name means 'small runner', and it was built for speed with long, slender legs.1

Scientists think Parvicursor was a juvenile, not a full-grown adult, because its bones show it was still growing.1

It lived about 72 million years ago, during the Late Cretaceous period.1

Some scientists think that Linhenykus and Ceratonykus might actually be the same animal as Parvicursor.1
