Dinosaur Tracks from the Caucasian Mineral Waters Country in the Context of the Study of Lower Cretaceous Paleosols of This Region

Abstract: This article examines the geological and stratigraphic context of several types dinosaur tracks discovered in Lower Cretaceous deposits exposed in the vicinity of city of Kislovodsk (Caucasian Spa Country; Stavropol Krai). The tracks occur on the bedding surfaces of Lower Cretaceous (Valanginian) limestones, dolostones and marls. Two track morphotypes are described. Some ideas are proposed on the paleoclimatic and environmental conditions in the region during Early Cretaceous times. We suggest that the tracks were produced in a coastal plain in the littoral zone of a marine basin (possibly, a brackish lagoon) during a warm, seasonally dry climate.
