Pygopterus is an
extinct
genus of prehistoric
bony fish that lived during the
Wuchiapingian to
Olenekian
ages (
late Permian to
Early Triassic
epochs) in what is now
England, Germany (
Baden-Württemberg,
Saxony-Anhalt),
Greenland and
Svalbard (Spitsbergen).
[2]
[3] It is one of the few genera of ray-finned fish known to cross the
Permian-Triassic boundary.
[3]
Fossils have been found in the
Marl Slate Formation,
Kupferschiefer (
Werra Formation),
Ravnefjeld Formation,
Vikinghøgda Formation and
Buntsandstein.
[1]
[2] A report about the discovery of this fish in
Westphalian deposits of Belgium was likely caused by the presence of
Nematoptychius which was referred to as Pygopterus in late 19th century.
