Cladoselachidae is an extinct family of cartilaginous fishes closely related to, and possibly nested within, Symmoriiformes.[1] They are characterized by having an elongated body with a spine in each of the two dorsal fins. In 2023, a paper describing a new cladoselachian, Maghriboselache found that it, and Cladoselache, were the only members of the family, greatly limiting the temporal range for this group to the Late Devonian.[2]
