Where: Kyongsangnam-do, South Korea (35.2° N, 128.1° E: paleocoordinates 43.1° N, 126.3° E)
When: Dongmyeong Formation (Gyeongsang Group), Late/Upper Aptian to Late/Upper Aptian (122.5 - 109.0 Ma)
• The horizon is the upper part of the Dongmyeong Formation of the Nagdong Subgroup in the Gyeongsang Group.
•
•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.
