On the basis of the lithological-facies analysis it was established that deposits of the Upper Itat Subformation comprising the Dubinino locality of the Middle Jurassic flora and insects (Sharypovo district Krasnoyarsk krai) accumulated in alluvial and lacustrine and to a lesser extent floodplain environments (floodplain and alluvial fan facies). The occurrence of remains of insects macroremains of flora spores and pollen allowed us to make a paleoreconstruction of an area with a strongly dissected relief: continental fresh-water reservoir (lake) with varying degree of overflow surrounded by hills covered with gymnospermous and ginkgo forests.
