Chukdongmyeon, Sacheonsi (KNUL collection) (Cretaceous of South Korea)

Where: Gyeongsangnam-do, South Korea (35.1° N, 128.0° E: paleocoordinates 44.3° N, 122.7° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Jinju Formation (Shindong Group), Albian (113.0 - 100.5 Ma)

• Dongmyeong Formation (=Jinju Formation). Formerly given a wide age range (often Barremian), but youngest detrital zircon in Jinju Formation is 106 Ma, indicating an age no older than Albian (Lee et al., 2010)

Environment/lithology: lacustrine - large; lithified, fine-grained, gray shale

• Initiated by north–south left-lateral regional simple shear as a wrench tectonic system due to highly oblique subduction of the Izanagi Plate (Lee et al., 2010)

Size class: macrofossils

Preservation: adpression

Collection methods: Repository: Kyungbook National University in Sangjusi, South Korea
