摘要：
The most complete characterization of Dictyochophyceae (silicoflagellate) assemblages from sediments of the Kronotskii Bay, Eastern Kamchatka, which are typical of the Corbisema hexacantha (Middle Eocene) and Naviculopsis foliacea (terminal middle-initial Late Eocene) zones in the tropical/subtropical zonation by Bukry (1981), is considered for the first time. In total, 43 silicoflagellate species of 8 genera are identified. The prevalence of species of the genera Corbisema and Dictyocha in the assemblages suggest warm, close to subtropical conditions in a sea basin that existed in the Eastern Kamchatka region during the Middle-Late Eocene.
