吃：植物長脖子恐龍白堊紀早期

Pilmatueia was a small, long-necked dinosaur that lived in what is now Argentina. It had tall, forked spines on its backbone, like a spiky fence. This plant-eater was a cousin of the famous Amargasaurus.1

酷東西

趣味知識

Pilmatueia lived during the Valanginian age of the Early Cretaceous, a time when dinosaur fossils are rare.1

Its backbone had air sacs that made the bones lighter, unlike most other dicraeosaurids.1

The forked spines on its neck vertebrae were low compared to its relative Amargasaurus.1

Pilmatueia shared its home with a small meat-eater called Lajasvenator and a type of podocarp tree.1

Its fossils were first dug up in 2009, but the dinosaur was named in 2019.1
