Where: Pakistan (32.7° N, 71.5° E: paleocoordinates 41.1° S, 56.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Chhidru Formation, Changhsingian (254.0 - 252.3 Ma)

• Not from the bed with silicified fossils, but from a bed of sandstone in which the fossils are contained in a calcareous condition. There is but little doubt that this sandstone forms part of the upper division of the Productus-limestone.

• group of beds-level stratigraphic resolution

Environment/lithology: lithified limestone

Size class: macrofossils

Preservation: replaced with silica
