Study history and research ethics of the dinosaur, pterosaur and bird tracks from Korea

Since 1972 when the dinosaur eggs were firstly discovered in Korea, for about 40 years we have known many dinosaur localities as well as track localities, pterosaur and bird tracks, which provide quite many papers. Therefore, the Ichnos, the international Journal for Ichnology has published the special volume titled as "Tracking on the Korean Cretaceous Dinosaur Coast (KCDC): 40 years of Vertebrate Ichnology in Korea", 2012, volume 29, which presented 13 papers about Korean ichnology. These papers were made by some study groups, that is, the Kim, J.Y. team of the Korea Education University, the Huh, M. team of the Chonnam National University, Lockley, M.G. of the Colorado University, Baek, I. S. of the Bukyeong National University, and Lim, J.D. of the National Research Institute of Cultural Heritage. Here, I will review on the story of my experiences about the discovery and study about the Korean Cretaceous dinosaur, pterosaur, bird tracks and the research ethics, and briefly introduce the results of recent studies of the 2nd generations mainly published on the Journal of Ichnos.
