Crustaceans have a rich and extensive fossil record, most of the major groups of crustaceans appear in the fossil record before the end of the Cambrian, namely the Branchiopoda, Maxillopoda (including barnacles and tongue worms) and Malacostraca; there is some debate as to whether or not Cambrian animals assigned to Ostracoda are truly ...
Branchioplax (Decapoda: Brachyura). This list of prehistoric malacostracans illustrates the genera from the fossil record that have ever been considered to be malacostracans, a class of crustacean arthropod, excluding purely vernacular terms.
Eocarcinus praecursor is a Jurassic species of decapod crustacean, sufficiently distinct from its relatives to be placed in its own family (Eocarcinidae). [1] Often considered the oldest true crab, it was considered by a 2010 study to be an early member of the Anomura. However, a reanalysis in 2020 again found it to be the earliest known stem ...

The order is estimated to contain nearly 15,000 extant species in around 2,700 genera, with around 3,300 fossil species. [1] Nearly half of these species are crabs, with the shrimp (about 3,000 species) and Anomura including hermit crabs , king crabs , porcelain crabs , squat lobsters (about 2500 species) making up the bulk of the remainder.

Anthracocaris is an extinct genus of crustaceans which lived during the Early Carboniferous period in Scotland.It is the only genus in the family Anthracocarididae.The genus contains a single species, A. scotica, which was first named as a species of Palaeocaris in 1882, but later recognized to belong in a separate genus.
The earliest fossils representative of Multicrustacea are from the Cambrian. [8] 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.
Cyclida (formerly Cycloidea, and so sometimes known as cycloids) is an extinct order of crab-like fossil arthropods that lived from the Carboniferous to the Jurassic and possibly Cretaceous. Their classification is uncertain, but they are generally interpreted as crustaceans, likely belonging to the superclass Multicrustacea.
