Berycopsis is an extinct genus of marine ray-finned fish from the Late Cretaceous period. Fossils are known from England, Germany, and Lebanon.[1][2] A potential specimen is known from the Czech Republic.[3]
It is generally placed among the beardfish in the family Polymixiidae. However, one 2009 study found it to be a more basal acanthomorph, and tentatively placed it as Beryciformes incertae sedis. However, later studies have continued to place it in the Polymixiidae.[4][5][6][7]
The following species are known:
- B. elegans Dixon, 1850 - Early Cenomanian to Turonian of the United Kingdom
- B. germanus (Agassiz, 1839) - Late Campanian of Germany (syn: B. oblongus von der Marck 1863)
- B. paucoradius Dietze, 2009 - Late Campanian of Germany
- B. pulcher Bannikov & Bacchia, 2005 - Late Cenomanian of Lebanon
The species Platycormus gibbosus von der Marck, 1885 may also belong to this genus, but the holotype has been lost and thus nothing about it is known. B. elegans and B. germanus may also be synonymous with each other, but not enough about the former's morphology to decide this.[4]
Berycopsis was about 35 centimetres (14 in) long and one of the earliest known members of the
