趣味知識

Lirainosaurus is known from a skull fragment, isolated teeth, several vertebrae, and limb bones.1

It lived alongside other dinosaurs like the titanosaur Ampelosaurus and the plant-eater Rhabdodon.1

Scientists think Lirainosaurus weighed about as much as a small car, between 2 and 4 metric tons.1

Its name comes from the Basque word 'lirain', meaning slender, because it had a light build for a sauropod.1

Lirainosaurus belongs to a group of sauropods called titanosaurs, which were common in the Late Cretaceous.1

Fossils of Lirainosaurus have been found in rocks that were once a coastal plain or shallow sea environment.1
