Where: Switzerland (47.2° N, 7.3° E: paleocoordinates 38.2° N, 16.3° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Röschenz Member (Vellerat Formation), Middle Oxfordian to Middle Oxfordian (161.2 - 155.7 Ma)
• Röschenz Beds formerly known as the Natica Beds (Gygi, 1995)
•the deposits from which the flora was collected are situated in a facies transition from the Günsberg to Röschenz Beds.
• bed-level stratigraphic resolution
Environment/lithology: coastal; claystone and marl
•Deposits are entirely marine with mainly oolites and pellets in the lower half of the section and marly, lagoonal limestones, containing red oncolites and bioclasts (mainly large gastropods) in the upper half). The material was collected from this facies transition.
Size classes: macrofossils, microfossils
Preservation: mold/impression, adpression, original carbon, original sporopollenin, original cellulose
Collection methods: bulk, chemical, mechanical, peel or thin section, sieve,
• Specimens stored in the Natur Museum Solothurn, the sedimentological samples are stored at the Geological Institute of the University of Basel.
