The species are primarily distinguished by the presence of a serrated edge on the front of the carapace of C. serrata. C. serrata is noted for the modification of an anterior pair of limbs into spined grasping appendages, indicating a predatory lifestyle.

叶足类Collinsium ciliosum发育了超乎想象复杂的背刺组合和用于滤食特化的附肢，表现出比其他近亲类群和现生的有爪动物更显著的形态分异和附肢的复杂化，因此在寒武纪大爆发期间开拓出独自的生态空间。 三叶虫Gunnia早期龄虫的磷酸盐化背壳显示，一最初出现在尾轴末端微小的“稚节” (immature ring)，在以往研究中多被忽视。 传统生长阶段的划分不过是将一连续的发育过程予以人为粗略的界定。 这些来自细微处的证据为探索三叶虫个体发育提供了新思路和有意义的信息 …
