Where: Gyeongsangnam-do, South Korea (35.0° N, 127.9° E: paleocoordinates 42.8° N, 126.2° E)

• coordinate estimated from map

• small collection-level geographic resolution

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

• 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)

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; paleosol/pedogenic, nodular, gray, green, sandy, calcareous mudstone

Size class: mesofossils
