Chinju City (Cretaceous to of South Korea)

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.
