“…The width of these ctenacanthoid scales ranges between about 0.75 and 1.5 mm. Similar scales are found in other localities (e.g., Duffin, 1998a;Mears et al, 2016;Landon et al, 2017;Ronan et al, 2020;Moreau et al, 2021;Williams et al, 2022).…”

“…The height of these scales is about 1 mm. This type of scale is mentioned from many localities of the British Penarth Group (e.g., Duffin, 1998a;Landon et al, 2017;Cavicchini et al, 2018;Ronan et al, 2020;Moreau et al, 2021;Williams et al, 2022) and also from Poland (Duffin & Gaździcki, 1977) and Luxemburg (Delsate & Duffin, 1999).…”

“…The presence of the lateral cusplets indicate that these teeth are anterolateral teeth (Duffin, 1998a, text fig. 20B;Korneisel et al, 2015;Slater et al, 2016;Cross et al, 2018;Moreau et al, 2021;Williams et al, 2022). The size ranges between about 2 and 3 mm.…”

“…Saurichthys was most likely a piscivorous predator (Moreau et al, 2021), as indicated by their sharp teeth. The species has also been mentioned from the various localities of the Penarth Group in the UK (Duffin, 1998a;Allard et al, 2015;Korneisel et al, 2015;Nordén et al, 2015;Slater et al, 2016;Lakin et al, 2016;Mears et al, 2016;Landon et al, 2017;Cavicchini et al, 2018;Cross et al, 2018;Ronan et al, 2020;Moreau et al, 2021;Williams et al, 2022), Eastern Europe (Duffin & Gaździcki, 1977;Michalík et al, 2013;Botfalvai et al, 2019) and Western Europe (Bürgin & Furrer, 1993;Duffin & Delsate, 1993;Delsate & Duffin, 1999;Diependaal & Reumer, 2021).…”

Chondrichthyan and actinopterygian fish remains from Rhaetian (c. 208.05–201.36 Ma) or perhaps Late Norian deposits in the Winterswijk quarry are described. The most abundant taxon is the actinopterygian Gyrolepis albertii, followed by the chondrichthyan Lissodus minimus. Furthermore, the palaeopterygian actinopterygians Saurichthys longidens and Birgeria acuminata, and some teeth of neopterygians Sargodon tomicus, ‘Lepidotes’ sp. and indeterminate pycnodontiforms are recorded in addition to the chondrichthyans Rhomphaiodon minor, Parascylloides turnerae and some ‘Hybodus’ cf. cuspidatus (senior synonym of H. cloacinus). Chondrichthyan dermal denticles, actinopterygian scales and gill rakers, tooth plates, and some fish bones were also found. There is considerable faunal resemblance to the various localities from the Rhaetian of the British Penarth Group, although it depends on the location as to whether chondrichthyans or actinopterygians prevail in the samples. On average, there are more chondrichthyan teeth present in the British samples than actinopterygian teeth, which is opposite to the situation in Winterswijk. That might be explained by different ecological circumstances, such as lower oxygen levels in bottom waters in Winterswijk and freshwater input and/or changes in salinity in the UK.
