  Haman Formation (South Korea) | |
The Haman Formation (Korean: 함안층; Hanja: 咸安層; RR: Ham-an-cheung) is an Early Cretaceous geological formationinSouth Korea. It has been dated to the Albian, with an estimated maximum depositional age of 105.4 ± 0.4 Ma.[1] The deposit is known for its tracks, including those of dinosaurs,[2][3] pterosaurs and birds.[4][5][6] It overlies the Silla Conglomerate which overlies the Chilgok Formation. It is laterally equivalent to the Sagog Formation.[7]
Fossil pterosaur, theropod, sauropod and ornithopod tracks have been recovered from this formation. Some dinosaur tracks show signs of display behavior. Dinosaur skin impressions have also been found in this formation.[8]
