Pinacosaurus

Description

Pinacosaurus est un genre éteint de dinosaures ornithischiens herbivores de la famille des Ankylosauridae qui vivait au Crétacé supérieur dans ce qui est aujourd'hui la Mongolie et la Chine.
Il avait au bout de la queue une sorte de massue dont il se servait probablement comme d'une arme : il la balançait avec assez de force pour pouvoir estropier ses ennemis. Il avait des dents petites et faibles adaptées à la consommation d'une végétation tendre.
