At least five major radiations in ancestral crustacean lineages produced the remipedes, cephalocarids, branchiopods, maxillopods, and malacostracans (Table 1).Scientists believe, either because of their primitive body forms or their fossil record, that all five major groups have ancient origins extending back at least as far as the beginning of the Paleozoic.

branchiopods (e.g. Notostraca, Anostraca and Spini- caudata), but their role in dispersal remains largely understudied (Bilton et al. 2001 ; Figuerola and Greenbranchiopods (fairy and tadpole shrimp) in seasonal water features occurring within and adjacent to the boundaries of the proposed project. The U.S. Fish and Wildlife Service (USFWS) survey protocol requires either two years of wet season surveys or one year of wet season surveys and one dry season survey (soil analysis) toA Modern Day Brachiopod. Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell.commonly termed 'large branchiopods', despite the group being clearly paraphyletic.
