Multicrustacea

The clade Multicrustacea constitutes the largest superclass of crustaceans, containing approximately four-fifths of all described non-hexapod crustacean species, including crabs, lobsters, crayfish, shrimp, krill, prawns, woodlice, barnacles, copepods, amphipods, mantis shrimp and others. The largest branch of Multicrustacea is the class Malacostraca (see below).

Notes:

Fossil record

The earliest fossils representative of Multicrustacea are from the Cambrian. However, the more specific timeline is uncertain. Some Cambrian fossils of uncertain taxonomic placement, such as those of Priscansermarinus, are nonetheless likely to be members of Multicrustacea.
