• According to Akhmetiev et al. (2009), the flora of Velikaya Kema is of the same age or similar to the other floras of the Engelhardia Beds of the Southern Primorie (Kraskino, Rettikhovka), The Near-shore Belt (Dembi), northern part of the Korean Peninsula and adjacent parts of Heilogjiang (China) (Ablajev et al. 2005). The age of the "Engelhardia Beds" was previously considered to be Early to Middle Miocene, but in recent years it was revised. Today these floras are dated as Oligocene, or possibly at the beginning of the Miocene. This view is due to changes in radiometric dating of the Oligocene/Miocene boundary and stratigraphic correlation of marine complexes (in particular planktonic faunas) on the Oligocene-Miocene transition in the Japan-Sakhalin region.
