The Uhangri Formation (Korean: 우항리층; Hanja: 牛項里層; RR: Uhangni-cheung), located at the Uhangri Dinosaur Fossil Site, is a geological formation from which fossil pterosaur tracks have been recovered near Haenam-eup, Jeollanam-do, South Korea.[2]

Fossil contents

Ichnofossils

Pterosaur tracks from the Uhangri Formation are housed at the Dinosaur Tracks Museum, of the University of Colorado at Denver and Chonnam National University, Gwangju, South Korea.[3]
