(Table 2) Overview of identified plant macrofossils of outcrop PG2038-1

For plant macrofossil analysis, each sample (~50 mL) was dispersed in water and sieved using 250-µm and 1-mm mesh sizes. The identifiable plant material (e.g. seeds, leaves, etc.) was picked using a Zeiss Stemi SV 11 and a Zeiss Stemi 2000-C stereo microscope. The identification of the selected macrofossils was carried out using different seed identification manuals (Beijerinck 1947; Berggren 1981; Anderberg 1994), and the reference collection at the AWI in Potsdam and the Senckenberg Research Station of Quaternary Palaeontology in Weimar. For taxonomic determination, we followed the Integrated Taxonomic Identification System (ITIS 2013), and in the case of Trichophorum cf. uniflorum we followed the World Checklist of Selected Plant Families (WCSP 2013). Species that could not be exactly identified were designated with cf. or within the genera using sp. According to Dierßen (1996), the identified taxa were categorized into different communities based on their environmental requirements.
