Where: Gyeongsangnam-do, South Korea (35.0° N, 128.0° E: paleocoordinates 42.9° N, 126.2° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Dongmyeong Formation (Gyeongsang Group), Late/Upper Aptian to Late/Upper Aptian (122.5 - 109.0 Ma)

• Dongmyeong Formation also known as Jinju Formation; Gyeongsang Supergroup

•

•Part of Gyeongsang Group (sometimes known as the Shinju Group). The Dongmyeong Formation is also known as the Jinju Formation. Hayashi (2006) suggested a late Barremian age for the Dongmyeong Formation based on ostracod assemblages, but Lee et al. 2010 obtained U-Pb dates of 112.4 +/- 1.3Ma for the lowermost Jinju Formation and suggested that deposition began in the late Aptian and lasted until the early Albian.

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; gray, calcareous mudstone
