NEW DATA ON COMPOSITION AND AGE OF MALOMIKHAILOVKA FLORA FROM THE UPPER CRETACEOUS OF THE AMUR RIVER LOWER COURSES

The described flora is studied near the village of Malomikhailovka, wh ere it is confined to synonymous formation of an intermontane depressi on at the northern end of the Sikhote Alin volcanic belt. In its domin ant taxa and in the composition of plant groupings, the studied flora notably differs from the coeval Tsagayan flora of the Zeya-Bureya depr ession and from floras occurring in western Sakhalin and eastern Sikho te Alin. It includes a new genus, Amurocyparis, with type species A. s okoloviae, as well as Larix puerensis sp. nov., Cryptomerites tutshkov ii sp. nov., Corylites amurensis sp. nov., and Palaeocarpinus pacifica sp. nov., which are described here. The latter taxon was discovered f or the first time in Russia.
