Chondrenchelys is an extinct genus of cartilaginous fish and the earliest member of Holocephali known from complete skeletons. Chondrenchelys would have been quite a relatively medium-sized fish with an elongated body up to in length, it had a dorsal fin which was indeed long and a body which tapered to a point. Chondrenchelys had one large pair, one middle-sized pair, and three small pair of tooth plates in each jaw. The genus name derives from the Greek word ÃÂÃÂýôÃÂÿÃÂ, meaning âÂÂgristleâ or âÂÂcartilageâÂÂ, and á¼ÂóÃÂõûàÃÂ, meaning âÂÂeelâÂÂ. The speciea name, problematicus, is likely derived from the lack of scales setting it apart from all other fish known at the time of discovery.
