 The Quedeklechiki locality of Permian vertebrates located in the south of the Perm region in the Quedinsky district was discovered in 2005 and quickly became known among paleontologists. The locality contains a rich complex of exceptionally preserved plants and vertebrates, fish, amphibians, and reptiles. Their remains are confined to limestones of various textures, which form two bone-bearing beds in the section of the quarry. However, the age of rocks remains a controversial issue. This research aims to analyze and compare various stratigraphic markers and discuss a number of existing stratigraphic inconsistencies in an attempt to arrive at a general conclusion about the age of the locality. According to geological survey data on a scale of 1,200 000, the Burevo sequence, Sheshmian formation, Euphimian stage, was identified in the territory of the quarry. At the boundary of the Sheshmian and Belebi formations, a mineralogical boundary is observed, which is manifested in a decrease in the proportion of. This article was authored by A. S. Bikiev, V. V.
