酷東西

趣味知識

Kryptops is one of the oldest known abelisaurids, a family of meat-eating dinosaurs that later included Carnotaurus.1

The outside of its upper jaw bone had deep grooves and pits, which suggests it was covered with a tight, horny covering like keratin.1

Kryptops lived about 112 million years ago during the Early Cretaceous period.1

Only one specimen of Kryptops has been found, and it includes an upper jaw bone, some back bones, ribs, and hip bones.1

Some bones that were first thought to belong to Kryptops later turned out to be from a different dinosaur, an allosauroid.1

關於 Kryptops 最常被問的問題

?How big was Kryptops?

About 6 to 7 metres (19.7 to 23.0 feet) long, which is similar in size to later abelisaurids like Carnotaurus.1

?What did Kryptops eat?

It was a meat-eater that probably ate dead animals like a hyena, using its short jaws and small teeth to gnaw on carcasses.4

?Did Kryptops have feathers?

Nobody knows for sure, but its face was covered in a hard, horny layer like keratin, not feathers.1

?Why did Kryptops have a rough face?

Its upper jaw had deep grooves and pits that probably held a tight, horny covering like a beak, which gave it the name 'covered face'.1

?Is Kryptops a dinosaur?

Yes, it is a dinosaur. It was a meat-eating theropod dinosaur from the Early Cretaceous period.1

?When did Kryptops live?

It lived about 112 million years ago, during the Early Cretaceous period (Aptian to Albian ages).1
