'''Dinocarida''' is a proposed taxon of [[fossil]] [[arthropod]]-like marine animals found in the early and middle [[Cambrian]]. Two subgroups are known, the [[anomalocarid]]s and the [[opabinid]]s. The name of this group comes from Greek, "deinos" and "caris," meaning "terror shrimp" or "terror crab," due to their vaguely crustacean-like appearance.
Dinocarids often had several pairs (usually 10) of swimming lobes. It is thought that these lobes moved in an up-and-down motion to propel the animal forward (the [[cuttlefish]] uses a similar technique to move around).
The placement of Dinocarida is uncertain: they appear to be allied to arthropods, but are unlikely to be [[crown group]] arthropods. Some taxonomists place them as a separate [[phylum (biology)|phylum]], others as a [[stem group]] within the phylum of arthropods. In some recent works they are grouped with other enigmatic forms in the phylum [[Lobopodia]].
