趣味知識

Mendozasaurus was the first dinosaur ever named from Mendoza Province in Argentina, and its name means 'lizard from Mendoza'.1

It belonged to a group called Lognkosauria, which includes some of the biggest titanosaurs like Futalognkosaurus and Puertasaurus.1

Scientists found 22 mostly connected tail vertebrae, a back vertebra, and many leg bones and bony plates called osteoderms.2

Mendozasaurus had special features in its vertebrae, like subtriangular pits in the back bones and a unique shape in the tail bones.2

Some of the fossils found were from a very large adult, about 15 percent bigger than the main specimen.2

Mendozasaurus lived during the Coniacian age, about 89 to 86 million years ago, in what is now Argentina.3
