The paper presents a project of regional stratigraphic units of the western Altai-Sayany folded regions in rang of horizons and sums up the studies of Devonian stratigraphy of the western Altai-Sayany folded region for the last 38 years. The regional horizons established by the authors are determined and traced over the whole region and are used in compiling of the second edition of the State geological map of Russia of the Kuzbass and Altai series sheets. The characteristics of the proposed horizons and justification of their age are given. The previous stratigraphic charts are reviewed. Some problems occur when a new generation of stratigraphic charts of the western Altai-Sayany folded region are drawn up. An alternative point of view on the name, stratigraphic position and sequence of the regional horizons is stated.

Keywords: Devonian, western Altai-Sayany folded region, regional stratigraphic units.
