Risin Spur (Gangamopteris Shales) (Permian to of India)

Also known as Lower Gondwanan series

Where: Kashmir, India (34.0° N, 74.9° E: paleocoordinates 54.8° S, 63.1° E)

• coordinate based on nearby landmark

When: Vihi Member, Asselian to Asselian (298.9 - 290.1 Ma)

• "collected from the Lower Permian Gangamopteris shales (glassy volcanic tuff) of the Lower Gondwana series". Age previously given as Rotliegendes but Gangamopteris shales correlated with Eurydesma-bearing beds at Manendragarh and the Salt Range, suggesting an Asselian-Sakmarian age.

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; tuffaceous shale

• "shales (glassy volcanic tuff)"

Size class: macrofossils

Preservation: mold/impression
