| Dinocaridida is a proposed extinct taxon of fossil arthropod-like marine animals found, with one exception, in the early and middle Cambrian. It is subdivided into the anomalocaridids and the opabinids. The name of this group comes from Greek, "deinos" and "caris", meaning "terror shrimp" or "terror crab", due to their crustacean-like appearance and the hypotheses suggesting that members of this class were the apex predators of their time.
