Haman Formation (South Korea)

The Haman Formation (Korean: 함안층; Hanja: 咸安層; RR: Ham-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]

Vertebrate paleofauna

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]

Ichnofossils

Ichnofossils of the Haman Formation
Ichnogenus Ichnospecies Region[8] Member Material Notes Image
Pteraichnus[9] P. isp. Namhae Pterosaur track, showing swimming traces.[8] Haman specimens housed at Korea National University of Education, Cheongwongun, South Korea.[9]
Dromaeosauripus D. hamanensis[3] Namhae Dromaeosaur track, belonging to a 70 cm (28 in) tall individual.
Neosauroides[10] N. koreanensis Lizard trackway
Koreanornis K. hamanensis Haman and Jinju Bird track; the first vetebrate ichnotaxon reported from South Korea.[11]
Caririchnium C. isp. Juvenile ornithopod tracks, belonging to either derived iguanodonts or basal hadrosauroids. The trackmakers' hip heights are estimated between 76.4 and 102.1 cm (30.1 and 40.2 in).[11]
