Yangshuling Mine Locality (Permian to of China)

Where: Hebei, China (40.0° N, 118.0° E: paleocoordinates 20.3° N, 89.3° E)

• small collection-level geographic resolution

When: Taiyuan Formation, Asselian to Asselian (298.9 - 290.1 Ma)

• The Taiyuan formation is considered to be of P1/1 (super and subscript) age in the Chinese stratigraphical system (Tian et al. 1996) correlating with the Asselian-early Sakmarian stages of the Early Permian elsewhere.

• bed-level stratigraphic resolution

Environment/lithology: mire or swamp; gray, green, calcareous tuff and gray mudstone

• Plant compressions are found in several lithologies, including dark grey coloured mudstones, grey coloured fine-grained sandstones and pale grey-yellow seat earth horizons, the latter dominated by poorly preserved and unidentifiable rooting organs.

•Permineralized plant fossils occur in fine-grained grey-green tuff in which the 3D structure and tissue compositions of the plant fossils are preserved. The tuff comprises predominantly sub-angular feldspar crystals in an early stage diagenetic carbonate matrix

Size class: macrofossils

Preservation: adpression, permineralized, original carbon, replaced with calcite

Collection methods: surface (float), chemical, peel or thin section,
