The Haman Formation (Korean함안층; Hanja咸安層; RRHam-an-cheung) is an Early Cretaceous geological formation in South 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]
