Based upon the abundant fossil plants collected from the Tsukabara Formation of the third of the five terraces recognized along the Pacific coastal area of Fukushima Prefecture in Northeast Honshu, Japan, analysis was made of the vegetation assemblages, interpretation of the paleoecology, determination of the geological age, and the relationship of the Tsukabara Formation to Pleistocene eustatic movements. From the results of investigation of the cited items it was judged that the fossil flora from the Tsukabara Formation represents the vegetation that fluorished during the last high sea-level and moderate climate of the Late Pleistocene age along the Pacific coast of Fukushima Prefecture. Remarks and or descriptions are given to certain of the plant species
