Pachycephalosaurus skull domes have intrigued us for decades and many palaeontologists think that they're an example of an intraspecific combat weapon.

几十年来，厚头龙的头骨穹顶一直吸引着我们，许多古生物学家认为它们是种内战斗武器的一个例子。

It's possible that the speedier juveniles hunted small herbivores, like the roughly 2-meter Leptoceratops or the 4.5-meter Pachycephalosaurus--while bite marks on fossils tell us the adults ate big game, such as Triceratops.

速度更快的幼龙可能会捕食小型食草动物，例如大约 2 米长的 Leptoceratops 或 4.5 米长的 Pachycephalosaurus——而化石上的咬痕告诉我们成年龙吃大型猎物，例如三角龙。
