Haenamichnus

pterosaurs. In 2002, paleontologists Koo-Geun Hwang, Min Huh, Martin Lockley, David Unwin and Joanna Wright named the type species Haenamichnus uhangriensis, based on fossil tracks they found in the Uhangri Formation of South Korea,^[1] dating to 81 to 79 million years ago during the Campanian.^[2] The largest track may have belonged to an individual reaching 10 m (33 ft) in wingspan, 3 m (9.8 ft) in height and 145 kg (320 lb) in body mass.^[3][4] A second species, H. gainensis, was discovered from the Haman Formation, but is now considered a bipedal crocodylomorph track reassigned to as Batrachopus cf. grandis.^[5]
