Stratigraphy
Geological group:Shindong Formation:Hasandong
Stratigraphic resolution:bed
Stratigraphy comments: 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)
Lithology and environment
Primary lithology:paleosol/pedogenic lithified calcareous mudstone
Includes fossils?Y
Lithology description: "70-cm-thick calcareous mudstone deposit"
Environment:wet floodplain
Geology comments: "fluvial floodplain...The bone bed underwent calcareous pedogenesis on the distal part of a floodplain under a semi-arid climate with alternating wet and dry periods and was subsequently buried by channel avulsion."
