Kongshan Hill, Nanjing (Permian of China)

Where: Jiangsu, China (32.1° N, 119.0° E: paleocoordinates 4.3° N, 96.9° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Qixia Formation, Kungurian (279.3 - 272.3 Ma)

• The Chihsia Formation overlies the Chuanshan Formation of Late Carboniferous age. In the Chihsiashan area to the NW it is overlain conformably by the Lower Permian Kuhfen Formation of Guadaloupian age.

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; limestone and cherty/siliceous shale

• The material comes from the middle of the Chihsia Formation, 93 mabove the bae. Fossils directly associated with calcareous algae in this silicified bed include fusuline and smaller foraminifers, bivalves, ostracodes, echinodermsand siliceous sponge spicules
• Limestone with chert nodules and siliceous shale.

Size classes: macrofossils, mesofossils
