section::::evolution.





























skates belong to the ancient lineage of cartilaginous fishes. fossil denticles (tooth-like scales in the skin) resembling that of today's chondrichthyans date at least as far back as the ordovician, with the oldest unambiguous fossils of cartilaginous fish dating from the middle devonian. a clade within this diverse family, the neoselachii, emerged by the triassic, with the best-understood neoselachian fossils dating from the jurassic. this clade is represented today by sharks, sawfish, rays and skates.
