Unfortunately, the fourth premolar in the upper jaw is quite large and looks like the first molar in the lower jaw; it is known as a carnassial tooth.

不幸的是，上颚的第四颗前臼齿很大，看起来就象是下颚的第一颗臼齿，这颗前臼齿也被称作叫裂齿。

They did have the carnassial teeth that distinguish the Carnivora, a pair of sharpened cheek teeth that are aligned so as to work like shears in slicing meat off bone;

它们已经有了食肉动物特有的裂齿，一对尖利的长在面颊部位的牙齿，能象大剪刀一样把肉从骨头上切割下来。
