==Discovery and naming== In 2002, paleontologists Koo-Geun Hwang, Min Huh, Martin Lockley, David Unwin and Joanna Wright named the type ichnospecies Haenamichnus uhangriensis, based on fossil tracks they found in the Uhangri Formation of South Korea. The ichnogeneric name means 'trace of Haenam County', while the ichnospecific name is in reference to the Uhangri Formation. The age of the Uhangri Formation is estimated around during the Campanian stage. Some Campanian azhdarchid tracks found in the Cerro del Pueblo Formation of Mexico and the Wapiti Formation of Canada might belong to this ichnogenus.
