Pholidophoridae is an extinct family of primitive stem-teleost fish that lived during the Triassic period, from the Anisian age of the Middle Triassic to the Norian age of the Late Triassic. Most of the genera are from Europe, but one (Malingichthys) is known from China.[1] The pholidophorids were historically united with several other stem-teleost lineages into the order Pholidophoriformes, but Pholidophoriformes in its traditional sense is now considered paraphyletic with respect to crown group teleosts.[4]
