Discloses the research results of dinosaur footprints in Yugok-dong, Ulsan
Professor Paik In-sung

The research team of Professor Paik In-sung (Department of Earth Environmental Sciences), of Pukyong National University, revealed that they discovered new evidence for the group life of herbivorous dinosaurs and the habit of a carnivorous dinosaur that hunts alone in the fossil-producing area of dinosaur footprints in Yugok-dong, Joong-gu, Ulsan (Cultural Heritage Data No.12 of Ulsan). According to Prof. Paik, it was confirmed that the preserved fossils of footpad skin impression supporting the fact that these footsteps were made almost simultaneously from 50 dinosaur footprints in 6 trackways in this fossil mountain area in Yugok-dong at the end of the Cretaceous Period (about 100 million years ago). This is the only case in Korea where skin impressions remain on most of the dinosaur footprints that form trackways in the fossil mountain area, and it is a rare case in the world. As a result of analyzing the behavioral characteristics of dinosaurs based on the preserved state of this trackway, Professor Paik's research team revealed that it was a scene where one carnivorous dinosaur (theropod) was hunting one herbivorous dinosaur (ornithopod) that followed behind the group.
This is new evidence that fossil footprints support that even carnivorous dinosaurs that lived in the Cretaceous Period, such as tigers and leopards today, had a single hunting habit. The research team said, this is new evidence that three different types of herbivorous dinosaurs moved together in groups on the shores of the lake. The researchers said that such fossil records indicate that the fossils of dinosaur footprints in Yugok-dong, Joong-gu, Ulsan were a lakeside area developed on flat land during the dinosaur period on the Korean peninsula, and this area was used as an important ecological space for dinosaurs during drought, like the African Savannah area. This research paper, conducted as personal basic research in the science and engineering field by the National Research Foundation of Korea, was published in the 4th issue (December) of 2020 「Episodes」, which is an international academic journal published by the International Union of Geological Sciences.
