“…They documented an environment that alternated between shallow marine and sabkha-like (hypersaline) intertidal mudflats (Oosterink & Winkelhorst, 2013;Klein et al, 2015;During et al, 2019). The intertidal nature of the deposits is emphasised by the preservation of algal laminates, polygonal mud cracks, burrowing traces, reptile trackways and reptile swimming traces (Knaust, 2013;Oosterink & Winkelhorst, 2013;Maxwell et al, 2016;Schulp et al, 2017;During et al, 2019;Marchetti et al, 2019). It should be noted that whereas saline conditions likely persisted throughout the entire stratigraphic profile, a hypersaline depositional environment has been suggested for the top section (top 10 m) of the stratigraphic profile in particular (During et al, 2019).…”

“…Furthermore, actinopterygian and chondrichthyan fish remains belonging to at least ten different genera have also been discovered (Haarhuis & Diependaal, 2019). An abundance of trace fossils has also been reported including invertebrate grazing traces, invertebrate burrowing traces, fish swimming traces, several different types of reptile trackways and reptile swimming traces (Knaust, 2013(Knaust, , 2015Schulp et al, 2017;Marchetti et al, 2019). In addition, many different invertebrate fossils have also been described, including mollusks (18 bivalve species, 2 gastropods and 1 ammonite), brachiopods (2 species), possible jellyfish and representatives of several clades of arthropods (e.g., Oosterink, 1981;Akkerman & Mulder, 2012;Oosterink & Winkelhorst, 2013;Klompmaker, 2019;Van Eldijk et al, 2019).…”

Horseshoe crabs (Xiphosura) have a long evolutionary history starting in the Ordovician, but they have rarely been reported from the Netherlands. We report on the first Triassic horseshoe crab from the Netherlands identifiable to the species level, a specimen of the limulid Limulitella bronnii. We provide the first diagnosis for this species and refigure the holotype. The new specimen was found in the Middle Triassic (Anisian) Muschelkalk sediments of the Vossenveld Formation, in the Illyrian part of the stratigraphic profile of the Winterswijk quarry complex. The Winterswijk specimen represents the youngest occurrence of L. bronnii. The inferred non-marine habitat of this horseshoe crab species elsewhere in conjunction with occurrences of plant and insect remains within the same layer at Winterswijk suggest the specimen herein most probably did not live in marine conditions either. This species has previously been found in non-marine sediments in France and Germany, expanding its geographic range northward. Several faunal elements from Winterswijk including L. bronnii show resemblance to the roughly co-eval non-marine components of the Anisian Grès à Voltzia Formation in NE France, suggesting a paleobiogeographic connection between these regions in Western Europe.

“…Remains of plants are mostly represented by palynomorphs (pollen and spores; Herngreen et al 2005b). In addition, numerous ichnofossils have also been identified, including burrowing traces (Knaust 2013), terrestrial track ways (Diedrich 2001) and swimming traces (Schulp et al 2017). An initial stratigraphy of the Winterswijk quarry was published by Oosterink (1986), who identified 39 stratigraphic horizons.…”

Despite its vernacular names (e.g. 'woodlice') Isopoda is a group with mostly aquatic species, with most species living in marine environments. The fossil record for isopods compared to other groups of Eucrustacea is relatively sparse. This applies even more for the Triassic. While in the Jurassic Isopoda is relatively well represented by fossils, only eight species have previously been described from the Triassic. In this study three new species of Isopoda are described from two field sites in Europe: Obtusotelson summesbergeri sp. nov. and Discosalaputium aschauerorum sp. nov. from Polzberg (Gaming, Lower Austria, Austria) and Gelrincola winterswijkensis sp. nov. from Winterswijk (Gelderland, Netherlands). All three new species are interpreted as representatives of Scutocoxifera (ingroup of Isopoda). The species Gelrincola winterswijkensis sp. nov. is further interpreted to be a representative of Cymothoida (ingroup of Scutocoxifera). Most of the oldest fossils of Isopoda belong to Phreatoicidea, which is supposed to be the sistergroup to all remaining Isopoda. Nowadays, Phreatoicidea is a small relic group, its representatives living in freshwater environments. The new species herein presented contribute to our understanding of the diversity of Isopoda in the Triassic and support the assumption that the transition from a dominance of Phreatoicidea towards the dominance of the remaining lineages of Isopoda happened quite early (likely prior to the Triassic).

“…This well-dated section, palynologically constrained at the Anisian (247.2-242 Ma;Herngreen et al 2005), has a rich fossil fauna, which has been subject to numerous palaeontological studies. These recovered ichnofossils and tetrapod footprints (Oosterink 1976;Demathieu and Oosterink 1988;Diedrich 2000;Schulp et al 2017), reptiles (nothosaurs and placodonts) (Albat 1999;Bickelmann and Sander 2008;Klein 2009Klein , 2012Klein and Albers 2009;Albers 2011;Klein and Scheyer 2013;Klein and Sichelschmidt 2014;Sander et al 2014;Klein et al 2015Klein et al , 2016Voeten et al 2015Voeten et al , 2018Maxwell et al 2016;During et al 2017;Klein and Griebeler 2018;Heijne et al 2019), but also lobsters (Klompmaker and Fraaije 2011), jellyfish (Klompmaker and Fraaije 2011), and insects (van Eldijk et al 2017). The Muschelkalk Formation contains widespread secondary mineralizations in cracks and pores, containing like pyrite and celestine (Kloprogge et al 2001).…”

In this paper, we provide two new Triassic palaeomagnetic poles from Winterswijk, the Netherlands, in the stable interior of the Eurasian plate. They were respectively collected from the Anisian (~247-242 Ma) red marly limestones of the sedimentary transition of the Buntsandstein Formation to the dark grey limestones of the basal Muschelkalk Formation, and from the Rhaetian (~208-201 Ma) shallow marine claystones that unconformably overlie the Muschelkalk Formation. The magnetization is carried by hematite or magnetite in the Anisian limestones, and iron sulfides and magnetite in the Rhaetian sedimentary rocks, revealing for both a large normal polarity overprint with a recent (geocentric axial dipole field) direction at the present latitude of the locality. Alternating field and thermal demagnetization occasionally reveal a stable magnetization decaying towards the origin, interpreted as the Characteristic Remanent Magnetization. Where we find a pervasive (normal polarity) overprint, we can often still determine well-defined great-circle solutions. Our interpreted palaeomagnetic poles include the great-circle solutions. The Anisian magnetic pole has declination D ± ΔD x = 210.8 ± 3.0°, inclination I ± ΔI x = − 26.7 ± 4.9°, with a latitude, longitude of 45.0°, 142.0°respectively, K = 43.9, A 95 = 2.9°, N = 56. The Rhaetian magnetic pole has declination D ± ΔD x = 32.0 ± 8.7°, inclination I ± ΔI x = 50.9 ± 8.1°, with a latitude, longitude of 60.6°, 123.9°r espectively, K = 19.3, A 95 = 7.4°, N = 21. The poles plot close to the predicted location of global apparent polar wander paths (GAPWaPs) in Eurasian coordinates and are feasible for future apparent polar wander path construction. They confirm that the intracontinental, shallow-marine Germanic Basin, in which the Muschelkalk Formation was deposited, existed at a palaeolatitude of 14.1°[11.3, 17.1] N, in a palaeo-environment reminding of the Persian Gulf today. In Rhaetian times, palaeolatitudes of 31.6°[24.8, 39.8] N were reached, on its way to the modern latitude of 52°N.
