What I think everyone can agree on is that stegosaurids are famous for good reason.

我认为每个人都能同意的是，剑龙科动物出名是有充分理由的。

Not all stegosaurids had thagomizers, but for those that did, like Stegosaurus and Kentrosaurus, fossil evidence suggests they were verrry effective weapons.

并非所有的剑龙科动物都有触骨器，但对于那些有触骨器的动物， 如剑龙和肯特罗龙，化石证据表明它们是非常有效的武器。
