Nectocarididae is a controversial family of animals that superficially resemble squids. Only two genera have been described, being Nectocaris (=Vetustovermis, Petalilium?) from the Cambrian period, and Nectocotis, from the Ordovician period.[2] Some researchers claim they are cephalopods, however, this is heavily disputed and most reject this claim.[3][4]
