Note on the Rhaetian fish fauna from a subrosion pipe in Winterswijk (the Netherlands), with a discussion on the validity of the genus Severnichthys Storrs, 1994

Abstract Fossil remains of fishes found in Rhaetian (Late Triassic, c. 208.5–201.3 Ma) sediments collected from a subrosion pipe in the Winterswijk quarry are described. The fauna shows great similarity to material known from the British Triassic of the Penarth Group and from other localities in Northwestern Europe. Both chondrichthyan and osteichthyan teeth and scales are present. Most abundant are the sharks Lissodus minimus and Rhomphaiodon minor and the actinopterygians Gyrolepis albertii , Saurichthys longidens and Birgeria acuminata . Isolated teeth of the latter two taxa were known unde... Mehr ...

Abstract Fossil remains of fishes found in Rhaetian (Late Triassic, c. 208.5–201.3 Ma) sediments collected from a subrosion pipe in the Winterswijk quarry are described. The fauna shows great similarity to material known from the British Triassic of the Penarth Group and from other localities in Northwestern Europe. Both chondrichthyan and osteichthyan teeth and scales are present. Most abundant are the sharks Lissodus minimus and Rhomphaiodon minor and the actinopterygians Gyrolepis albertii , Saurichthys longidens and Birgeria acuminata . Isolated teeth of the latter two taxa were known under the name Severnichthys acuminatus , but the genus Severnichthys is here considered a nomen dubium ; it should be suppressed in order to make the taxonomy less complicated.
