Also known as Kalsa-ri, Galsari; Pukyongosaurus millenniumi type

Where: Gyeongsangnam-do, South Korea (34.9° N, 127.8° E: paleocoordinates 42.8° N, 126.1° E)

• coordinate based on nearby landmark

• 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: wet floodplain; lithified, paleosol/pedogenic, calcareous mudstone

Size class: macrofossils

Preservation: trace

Collected in 1998–2000
