Stratigraphy
| Geological group: | Middle Buntsandstein | Formation: | Solling | Member: | Trendelburg/Karlshafen Beds |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: “Solling-Bausandstein” (“Solling building sandstone”), upper Middle Buntsandstein (“Bunter”), Solling Formation (equivalent to the Trendelburg/Karlshafen Beds). The lower part of the Solling Formation (Wilhelmshausen Beds, Trendelburg Beds and Karlshafen Beds) consists of coarse fluvial deposits that are dated on the basis of palynomorphs, conchostracans and palaeomagnetic data as latest Olenekian (late Spathian).
Based upon radiometric estimates for the Olenekian–Anisian boundary (247.2 Ma) and data on the number of short eccentricity Milankovitch cycles present within the Solling Formation, Kozur & Bachmann (2005, 2008) inferred a date of ~247.5 Ma for the base of the Solling. This would suggest an age of approximately 247.5–247.2 Ma (latest Olenekian) for the holotype specimen of Ctenosauriscus (Butler et al. 2011) | |||||
