The following is a terrestrial chronology charting the arrival of Galactic superwaves, cosmic dust incursions, extreme solar events, and glacier wave flood events during the past 67,000 years. It is divided in two parts, 67 kyrs BP to 19 kyrs BP and 19 kyrs BP to the present. All dates have been converted to the Cariaco Basin radiocarbon dated varve chronology published by Hughen (2006). References given in column 3 of the tables are given below. Generally, the sequence of solar cosmic events that I hypothesized has shaped the history of our planet go as follows:
Galactic superwave arrival -- cosmic dust incursion -- solar activation -- extreme solar flares -- glacier wave floods -- extinction
The main graphs that have been relied on to construct this chronology are also given below. Other information is given in the cited references. For table II also consult the posting at: https://etheric.com/cosmic-dust-incursion-solar-cause-mass-extinction/.
