Acentrophorus is an extinct genus of prehistoric ray-finned fish from the Wuchiapingian (Lopingian/late Permian) of England (Marl Slate) and Germany (Kupferschiefer).[1] There may also be a Triassic occurrence in Australia.[2]

Classification

The type species, Acentrophorus glaphyrus, was first described under the genus name "Palaeoniscus" (=Palaeoniscum) by Louis Agassiz.[3] Ramsay H. Traquair later errected a new genus for this species, Acentrophorus, to which he also referred the species "Palaeoniscus" abbsii, "P." altus and "P." varians.[4]

Acentrophorus has been referred to the ginglymodian order Semionotiformes.[5] Acentrophorus was proposed to be the oldest known neopterygian,[6] the group of ray-finned fish that encompasses the vast majority of extant species. However, the genus has been described as "enigmatic"[7] and "pending restudy".[8]
