Nakdong Formation
The Nakdong Formation (Also known as the Nagdong Formation) (Korean: 낙동층; Hanja: 洛東層; RR: Nakdong-cheung) is an Early Cretaceous (Hauterivian to Aptian) geologic formation in South Korea. It has been dated from the Hauteravian to the Aptian, between 127 Ma and 118.0 ± 2.6 Ma. Plant fossils from the Nakdong Formation show 'mixed type' of the Tetori-Type and the Ryoseki-Type flora existed in this formation. Sauropod fossils have been reported from the formation, although none have yet been referred to a specific genus.
