The Uhangri Dinosaur Fossil Site area was originally covered by ocean, uncovered when Lake Damsuho, and surrounding area, was created by the construction of the Geumho Tide project.
Lake Damsuho has cliffs that are 3 to 4 metres (9.8 to 13.1 ft) high, stretching across about 5 kilometres (3.1 mi), made up of sedimentary rock formed during the Cretaceous age. Embedded in the rock formations around the lake are fossilized footprints of dinosaurs, pterosaurs and water birds that lived in this area tens of millions of years ago.
No other place in the world has fossil footprints of all these different dinosaurs found in a single area. The footprints of a pterosaur discovered in this area is the largest in the world at a length of 20 to 35 centimetres (7.9 to 13.8 in).[3]

Pterosaur tracks
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.[4]
