• The upper part of the Pleistocene Atsumi group is called Toyohashi formation, which is composed of four members and superposed on the middle part of the group with local disconformity.The plant remains of this formation are separately occurred in two horizons, the lower of which indicates a cooler climatic condition, whereas the upper suggests warmer and drier one than that of recent date. Hence this formation is inferred to represent an interglacial deposit as a whole, although its lower part implies the influence of the glacial or subglacial climate immediately before the deposition of this formation.The Toyohashi formation may be referred to the late Pleistocene in age, judging from the predominance of Pinus Thunbergii, Aleurites cordata, Melia Azedarach and Mallotus japonicus, etc.
