The features of the section of the Lower and Middle Devonian deposits of the northern part of the Southern-Minusinsk Trough are described. A detailed section of the Toltakovskaya Formation deposits has been compiled. The formation is classified as Middle Devonian on the basis of relationships with underlying and overlying formations, structural and tectonic features and cyclic recurrence of sedimentation processes embodied in the section. The composition, internal structure and volume of the stratigraphic subdivisions of Lower and Middle Devonian are considered, their paleontological characteristics indicating new locations of fossil flora and fauna are given.

Keywords: Southern-Minusinsk Trough, Middle Devonian deposits, Toltakovskaya Formation.
