Abstract
New angiosperms from the Emuneret Formation of the Enmyvaam River basin are described: Menispermites lebedevii sp. nov., Cissites reticulatus sp. nov., Viburniphyllum emuneretum sp. nov., and Dicotylophyllum stipulare sp. nov. These species are characteristic elements of the Ust’-Emuneret floristic assemblage, which occur from the volcanogenic deposits of the late stage of the development of Okhotsk-Chukotka volcanogenic belt. The floristic assemblage includes 57 species of fossil plants. It is characterized by dominant angiosperms, subdominant conifers, and subordinate ferns, liverworts, ginkgoaleans, and czekanowskialeans. Macrofloristic study indicates the Santonian-Early Campanian age of plant-bearing deposits.
