Lithology and environment
Primary lithology: | desiccation cracks,wave ripples,gray,blue lithified "limestone" |
Includes fossils? | Y |
Lithology description: "The presence of bluish-gray limestones and marls, yellowish dolomites and black-grayish mudstones indicate a shallow marine and near shore environment. Sediments with ripple marks and polygonal mud cracks even indicate a tidal flat facies, with the mud crack beds representing algeal laminates produced by cyanobacteria stabilizing the sediment surface. Bones of Muschelkalk reptiles occur accumulated in specific layers, for example in bed IX" "The present skull was found in what is described as layer 9 by Oosterink (1986), which relates to what Harsveldt (1973) described as lower Wellenkalk, located 0.70–0.95 m below a distinct chocolate brown calcareous marl layer and 0.74–0.99 m above Dolomitic Limestone VI (Harsveldt, 1973)."
