酷東西

趣味知識

Murusraptor belongs to a group called Megaraptoridae, which are known for their long snouts and very air-filled bones.1

The only known skeleton of Murusraptor was found in the wall of a canyon, which is why its name means 'wall thief'.1

Even though the holotype was not fully grown, it was already about 6.5 meters (21 feet) long, making it larger than some other megaraptorids.1

Murusraptor had a large opening in its lower jaw called a mandibular fenestra, which helped make its skull lighter.1

The tail vertebrae of Murusraptor had knob-like bumps on their sides, a feature that helps scientists identify it.1

Scientists are still debating whether megaraptorids like Murusraptor are more closely related to Allosaurus or to Tyrannosaurus.1

你們都在問

關於 Murusraptor 最常被問的問題

?How big was Murusraptor?

About 6.4 metres (21 feet) long. The only known fossil was not fully grown, so adults may have been larger.3

?What did Murusraptor eat?

It ate meat. It was a carnivorous dinosaur with long, narrow snout and small teeth, probably hunting other animals.3

?When did Murusraptor live?

It lived during the Late Cretaceous period, about 89 to 86 million years ago (Coniacian age).3

?Could Murusraptor run fast?

Nobody knows for sure. Its leg bones suggest it was a fairly agile predator, but exact running speed is not known.3

?Why is it called Murusraptor?

Its name means 'wall thief' because the only skeleton was found in the wall of a canyon. 'Murus' is Latin for 'wall', and 'raptor' means 'thief'.3

?Was Murusraptor a dinosaur?

Yes, it was a theropod dinosaur, a type of meat-eating dinosaur. It is not a pterosaur or marine reptile.3
