Proconodontida is an order of conodonts which originated in the late Cambrian (Furongian) and persisted partly through the Ordovician.[1] The ancestral proconodont, Proconodontus, was one of the earliest euconodonts ("true conodonts") to appear. Proconodonts are often equated with the broader group Cavidonti, which occupies one side of a basal division in the evolution of early euconodonts in the Cambrian. All other euconodonts occupy Conodonti, the other side of the Cambrian split.[1]
Proconodontida may be ancestral to another order, Belodellida.[1] Belodellids originate in the Ordovician and survive up to the Devonian[1] or even the Permian (if Caenodontus qualifies as a member of the order).[2]
