现存的小型食肉动物的生态形态学研究表明，饮食组可以区分使用数量形态特征。小型（< 10公斤）的现代食肉动物分为三类：食肉动物、食虫动物和杂食动物/硬物进食者。统计分析显示，这些类之间的差异，包括更长的carnassial刀片在食肉动物，而不是更大的磨牙研磨面积，更大的后犬齿列，更广泛的第四前磨牙杂食动物/硬物馈线。食虫动物并不总是与其他饮食类型区分开来，尽管它们确实倾向于有较弱的牙齿和较短的颞肌力矩臂。这些趋势可以用来帮助解释不确定的生态，包括化石类群的类群形态。
An ecomorphological study of extant small carnivorans demonstrates that dietary groups can be distinguished using quantitative morphological characters. Small (< 10 kg) modern carnivorans were divided into three dietary classes: carnivores, insectivores and omnivores/hard-object feeders. Statistical analyses revealed differences between these classes including longer carnassial blades in carnivorans, as opposed to larger molar grinding areas, larger post-canine dentitions, and wider fourth premolars in omnivores/hard-object feeders. Insectivores are not consistently distinguished from other dietary types, although they do tend to have weaker dentaries and shorter temporalis muscle moment arms. These trends can be used to help interpret morphologies of taxa of uncertain ecologies, including fossil taxa.
