酷東西

趣味知識

Mantellisaurus was once thought to be a species of Iguanodon, but scientists gave it its own genus in 2007.1

Its forelimbs were only about half the length of its hindlimbs, so it probably walked on two legs most of the time.1

A nearly complete skeleton was found in a quarry in Nehden, Germany, in 1971, along with bones of Iguanodon and crocodiles.1

The first fossil of Mantellisaurus was discovered on the Isle of Wight, England, in 1914 and named Iguanodon atherfieldensis.1

Some scientists think the Belgian specimen IRSNB 1551 belongs to a separate genus called Dollodon, but others disagree.1

Mantellisaurus weighed about 750 kilograms (1,650 pounds), as heavy as a small car.1
