趣味知識

Chucarosaurus belonged to a group of giant titanosaurs called Colossosauria, which includes some of the heaviest land animals ever.1

Its thigh bone (femur) was about 1.9 meters (6.2 feet) long, showing it was a truly massive dinosaur.1

The name Chucarosaurus comes from a Quechua word meaning 'hard and indomitable animal,' like a wild horse.1

Its arms and legs were surprisingly slender for such a huge dinosaur, which is unusual among giant titanosaurs.1

Chucarosaurus lived about 100 million years ago, during the middle of the Cretaceous Period.4

Only a few limb bones have been found, so scientists are still learning about this dinosaur.1
