B. P. Markovskiy’s 130th anniversary: Key sections and brachiopods of the Frasnian Stage in the South Urals western slope (unpublished)

Boris P. Markovskiy is a famous national scientist, prominent representative of the scholarly school at the All-Union Geological Research Institute (VSEGEI — currently Karpinsky Institue, Saint Petersburg). He devoted most of his life to studying the Ural subsoil areas and geological history, and his legacy was profound: books, articles, paleontological collections, unpublished papers. The article presents B. P. Markovskiy’s materials from his paper Frasnian Stage brachio-pods in the West Urals (1948), which Karpinsky Institute stocks. The major part of the paper covers detailed descriptions of the Upper Devonian Frasnian Stage sections in the basin of the Zigan and Zilim rivers, as well as monographic descriptions of 121 brachiopod taxons, 37 of which B. P. Markovskiy was the first to identify. It is currently the most complete taxonomic composition of the Frasnian brachiopods from the South Urals western slope sections. The article pays tribute and respects to our senior colleague and master.
