At the 1973 Burg Wartenstein Symposium, it was recommended that “The beginning of the Middle Pleistocene should be so defined as to either coincide with or be closely linked to the boundary between the Matuyama Reversed Epoch and the Brunhes Normal Epoch of paleomagnetic chronology”. This was finalized in 2020, when the Executive Committee of the International Union of Geological Sciences officially ratified the

and the hypothesis advanced that the field had reversed in the past, Matuyama was the first to conduct a disciplined study of the hypothesis. In 1926 he began collecting basalt specimens in
