... of substrate and water depth, on the composition of the benthic faunas. The Wegener Halvø and Schuchert Dal Formations (Lopingian) in central East Greenland contain a diverse brachiopod fauna that is comparable to that of the post-Vøringen Member in Spitsbergen. This implies that the brachiopods...

... such as taeniate and non-taeniate bisaccate gymnosperm pollen (pteridosperms and conifers) shows no significant change across the boundary, whereas spores and other gymnosperm pollen increase in diversity and abundance. These changes coincide with the formational change between the Schuchert Dal Formation (Upper...

... of the overlying Schuchert Dal Formation ( Scholle et al . 1993 ). This unit is generally divisible into an Oksedal Member (silty shales) and a Bredehorn Member (micaceous sandstones with limestone boulders derived from the Wegener Halvø Formation) ( Surlyk 1990 ), although in the Wegener Halvø area the Schuchert...

The Changhsingian-aged Schuchert Dal Formation, up to 220 m thick, represents the latest Permian basin fill, where relative sea-level rise caused drowning of the carbonate buildups and deposition of grey-black silty bioturbated...

... ( Fig. 3 ) appear to show a gradual disappearance of the shelly taxa in the upper 5 m of the Schuchert Dal Formation. However, these data are the result of a single field season and are certainly subject to collecting bias. Numerous studies (e.g., Marshall, 1995 ) have shown that collecting...

... turbidite sandstones of the Schuchert Dal Formation are in part contemporaneous with the mudstones and carbonates, and are interpreted as deposited during relative sea-level lowstands ( Kreiner-Møller & Stemmerik 2001 ). In the deepest parts of some half-grabens, the Permian–Triassic boundary...

... laminated, dark-gray siltstones are interbedded with massive, fine-grained sandstones. The middle interval is correlated with the Ravnefjeld Formation of East Greenland, whereas the upper interval shows many similarities with the Schuchert Dal Formation. The Ravnefjeld Formation is a lateral equivalent...

The youngest Permian strata in East Greenland consist of the Wegener Halvø Formation and the overlying Schuchert Dal...

..., 1990 ). An increased siliciclastic supply and a relative fall of sea level led to deposition of the green-gray bioturbated shales and sandstones of the Schuchert Dal Formation above the Ravnefjeld Formation ( Surlyk et al., 1986 ; Stemmerik, 2001 ) ( Fig. 1 ). Our samples were collected from...

Near the top of the formation (in the upper 50cm), small trilete cavate spores appear, and these were considered to indicate a Triassic...

Recently, Looy (pers. comm.), has extended the range of O. eotriassicus into the uppermost 15 cm of the Schuchert Dal Formation (9.35 m...

Variably silty shales of the Schuchert Dal Formation are overlain by darker shales of the Wordie Creek Formation, with the extinction occurring at the formational boundary.
