Pancrustacea is the clade that comprises all crustaceans and all hexapods (insects and relatives). [2] This grouping is contrary to the Atelocerata hypothesis, in which Hexapoda and Myriapoda are sister taxa , and Crustacea are only more distantly related.
Paulinecaris is tentatively assigned to Entomostraca due to the morphology of its maxillae and other appendages, possibly close to Yicaris and cephalocarids, [1] however Entomostraca is a paraphyletic clade [2] and therefore its position in Pancrustacea is uncertain.

Allotriocarida is a clade of Pancrustacea, containing Hexapoda (all insects, springtails & their close relatives). It also contains three non-hexapod classes: Remipedia (blind, venomous crustaceans), Cephalocarida (translucent aquatic detrivores), and Branchiopoda (freshwater, non-decapod 'shrimp').
Abludomelita obtusata, an amphipod. Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are a part of the subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods ...
Yicaris dianensis is a species of microscopic pancrustacean [1] [2] found in the Yu’anshan Formation, Yunnan Province, China. [3] Yicaris' discovery is notable because its age suggests that true crustaceans already existed as far back in time as Early Cambrian, much earlier than other fossils known from the Middle and Late Cambrian.
If this proposition holds true, the Myriochelata are the sister clade to the Pancrustacea (also Tetraconata), comprising classic crustaceans and hexapods. The evidence for this relationship between myriapods and chelicerates derives from comparisons of nuclear ribosomal RNA genes, mitochondrial ribosomal RNA genes, and protein-coding genes.
Crustaceans are members of the sub-phylum Crustacea, a large group of arthropods (55,000 species).They include various familiar animals, such as lobsters, crabs, shrimp and barnacles.
