So from their own, separate starting points, the nimravids, the barbourofelids, and the true cats each wound up with its own type of sabertooth species.

因此， 从它们各自不同的起点出发，猎豹科动物、巴氏猫科动物和真正的猫科动物都以自己的剑齿虎物种类型结束。

Which was fine, because the bone-crushing dogs and cat-like nimravids already occupied the role of large predator, so being small let canines take advantage of smaller prey with less competition.

这很好， 因为粉碎骨头的狗和像猫一样的猎犬已经占据了大型捕食者的角色，所以体型小让犬科动物可以在竞争较少的情况下利用较小的猎物。
