West of Tuanwan, Laiyang basin (Cretaceous of China)

Where: Shandong, China (36.8° N, 120.6° E: paleocoordinates 40.2° N, 122.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Laiyang Formation, Aptian (125.0 - 113.0 Ma)

• Third member, bed 9

Environment/lithology: lacustrine - large; lithified shale

• Large (several hundred km2) lake in the Laiyang basin. In addition to the abundant entomofauna, plant fossil fragments, fish and a single bird feather also have been found. Water plants were apparently rare, and at the centre of the lake I have found no plant or animal fossils.
• The Third Member of the Laiyang Formation consists of 250-705 m of calcareous sandstone, siltstone and fine-granted sandstone intercalated with thin, paper-like, insect-rich shales.

Size classes: macrofossils, mesofossils

Preservation: mold/impression
