Abstract;By clustering the species lists of Cenozoic Bivalvia of the Russian Far East, Kafanov and Ogasawara (2003), have recognized eleven bivalve cenozones for the entire northwestern Pacific, as follows: 1-extant species; 2-Fortipecten takahashii-Yoldia (Cnesterium) kuluntunensis; 3-Acila (Truncacila) marujamensis-Lucinoma acutilineata; 4-Mya cuneiformis-Acila (Truncacila) gottschei; 5-Mytilus (Tumidimytilus) tichanovitchi-Macoma osakaensis; 6-Megayoldia (Hataiyoldia) tokunagai-Neilonella (Borissia) sakhalinensis; 7-Periploma (Aelga) besshoensis-Yoldia (Yoldia) kovatschensis; 8-Papyridea (Profulvia) harrimani-Ciliatocardium asagaiense; 9-Megayoldia (Portlandella) watasei-Yoldia (Nampiella) takaradaiensis; 10-Nuculana (Saccella) gabbii-Corbula (Cuneocorbula) formosa; 11-Lucina washingtonensis-Nuculana (Saccella) alaeformis. These cenozones occur widely on Sakhalin and the Kurile Islands, in formations with geological ages cited here. The boundary between the Paleogene and the Neogene is at the base of the Mytilus (Tumidimytilus) tichanovitchi-Macoma osakaensis cenozone, which corresponds to the bases of the Uynin Horizon and the upper subsuite of the Nevel'skaya Suite on Sakhalin.
