pdf  Sphenobaiera Florin (Ginkgoales) genus and its importance for Jurassic deposits stratigraphy of Irkutsk coal basin
The results of systematic composition clarifying of Sphenobaiera Florin (Ginkgoales) genus, one of the dominant taxa in the Jurassic flora of Irkutsk basin, are given. Remains of genus leaf were found almost in all outcrops of Prisayan and Cheremkhovo suites deposits. The six species of the genus, two of which are new, were identified by the peculiarities of the leaves epidermis structure. Stratigraphic confinement of identified taxa was traced.

Keywords: Lower and Middle Jurassic, Sphenobaiera, stratigraphic region, Irkutsk coal basin.
