Haenamichnus Explained

Haenamichnus is an ichnogenus that has been attributed to azhdarchid 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 in wingspan, in height and 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]
