On the Composition and Age of Taphofloras of the Krivorechenskaya Formation (Upper Cretaceous) of the Anadyr River Left Bank, Northeast Asia

Abstract Chineiveem taphoflora from the Krivorechenskaya Formation of Anadyr River left bank (Northeast Asia) is characterized by a relatively low diversity plants represented ginkgoaleans, conifers, and angiosperms. Judging their systematic composition, this younger than Grebenka flora basin. Its closest analog Penzhina Northwestern Kamchatka Yelistratov Peninsula, age which reliably defined as Turonian, excluding beginning Turonian. Therefore, floristic assemblage also most probably late Such dating in agreement with Turonian or Coniacian marine mollusks overlying Dugovskaya layers conformable stratigraphic contact these plant-bearing beds. A tectonic between deposits not supported our paleobotanical data. The observed succession taphofloras Ubiyenka–Chineiveem interfluve suggests that upper limit
