Haman Formation


The Haman Formation 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. The deposit is known for its tracks, including those of dinosaurs, pterosaurs and birds. It overlies the Silla Conglomerate which overlies the Chilgok Formation. It is laterally equivalent to the Sagog Formation.

Vertebrate paleofauna

Fossil pterosaur, theropod, sauropod and ornithopod tracks have been recovered from this formation. Some scratch marks made by theropod tracemakers show signs of avian-like courtship display behavior. Dinosaur skin impressions have also been found in this formation.
