Also known as Yusu-ri, Jinju

Where: Gyeongsangnam-do, South Korea (35.1° N, 128.0° E: paleocoordinates 43.0° N, 126.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

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

• 8 track-bearing horizons; 7 represented here. Upper part of formation

•Previously, a Hauterivian-Barremian age for the Hasandong Formation was proposed, based on palynomorph assemblages (Choi, 1985; Choi, 1989; Yi et al. 1994). However, molluscan faunas suggest and Aptian-Albian age (Yang 1982) and Lee et al. 2018 SHRIMP and U-pb analyses provided a maximum depositional age of approximately 118+/-2.6Ma. The youngest detrital zircon ages were approximately 109Ma (Lee et al. 2010)

• group of beds-level stratigraphic resolution
