Dinocaridida[derivation 1] is a proposed fossil taxon of basal arthropods,[3] which flourished during the Cambrian period and survived up to Early Devonian. Characterized by a pair of frontal appendages and series of body flaps, the name of Dinocaridids (Greek for deinos "terrible" and Latin for caris "crab") refers to the suggested role of some of these members as the largest marine predators of their time.[3] Dinocaridids are occasionally referred to as the 'AOPK group' by some literatures,[4][5][6] as the group compose of Radiodonta (Anomalocaris and relatives), Opabiniidae (Opabinia and relatives), and the "gilled lobopodians" Pambdelurion and Kerygmachelidae.[7] It is most likely paraphyletic, with Kerygmachelidae and Pambdelurion more basal than the clade compose of Opabiniidae, Radiodonta and other arthropods.[4][8][9]
