Abstract
The Koryak phase of the floristic development in the Northern Pacific frame is discussed. Newly obtained data on the Koryak Flora from the Amaam Lagoon area (Northeastern Russia) and Paleocene floras of the Northern Alaska have extended geographic and temporal ranges of the phase. Interregional statuses of the Koryak phase and phytostratigraphic horizon based on this phase, which is traced over the entire Northern Pacific frame and not just the Anadyr-Koryak region as was earlier supposed, are substantiated. The upper boundary of this horizon is defined; the age ranges from the Late Maastrichtian-Danian to Early Selandian.
