  • 초록

    A total of 57 dinosaurs footprints were discovered on a river bed of Shin-chun, Daegu city, which are exposed on a single horizon of the Cretaceous Banyawol Formation. A majority of dinosaurs footprints have been highly eroded mainly because the horizon of dinosaurs tracks are exposed on the river. As a result, original morphology of the dinosaurs foot is distorted in general, and only a few tracks with toes are preserved. Especially No. 55 footprint is well preserved containing clear five toes. The dinosaurs foot prints displaying a direction are identified as Q2 type according to Lim's classification. As for the size of the sauropod track, F1 ranges from 20 to 56 ㎝, FW from 22 to 60 ㎝, and depth of the footprint is 1-17 ㎝. By the dinosaur′s track and mudcrack, it is estimated that a bed within which tracks were found was deposited in a shallow lacustrine environment.
