新的发现证实古代两足生物剑角龙可以打败现今顶级的善于头部撞击生物。
The new findings confirm that the ancient bipedal dinosaur Stegoceras could knock out any of today's top head-butters.
剑角龙是属于肿头龙类食叶属之一，这种物种生存于7千万年前的地球。
Stegoceras was a member of the leaf-eating genus Pachycephalosauria that roamed the Earth around 70 million years ago.
“那么有了这些证据那些关于剑角龙的头部不能承受头部撞击的压力的讨论似乎被驳倒了”Theodor博士说道。
"The argument that they couldn't withstand the forces of head-butting seems to have been refuted by this evidence," said Dr Theodor.
和现今的一些大型的头部撞击生物相比，如北美的大角羊，北极的麝香牛和非洲的小羚羊，剑角龙的头部可以承受更大的压力。
Compared to some of today's big hitters, such as the Northern American bighorn sheep, the Arctic musk ox and African duiker, Stegoceras' head was able to withstand the most stress.
