Fun facts

Mandschurosaurus was the first dinosaur genus ever named from China.1

Its name means 'lizard from Manchuria' because it was found in Manchuria, a region in northeastern China.1

The skeleton on display in St. Petersburg is mostly plaster because the real bones were poorly preserved.1

Some scientists think Mandschurosaurus might not be a valid genus and call it a nomen dubium (doubtful name).1

It lived during the Late Cretaceous period, about 72 to 66 million years ago.1

The largest Mandschurosaurus could weigh as much as a small car, around 1.5 to 2 metric tons.1
