Here we present a new paleoshoreline chronology that extends over past 100 k.y. Lake Mega-Frome, coalescence Lakes Frome, Blanche, Callabonna Gregory, southern latitudes central Australia. We show Mega-Frome was connected last adjacent Eyre 50–47 ka, forming largest remaining interconnected system paleolakes on continent. final disconnection progressive drop level represents major shift coincided with arrival demise megafauna. supply moisture continent various times Quaternary has commonly been ascribed enhanced monsoon. study, combination paleoclimate data, provides reliable evidence periods tropical Southern Ocean sources water filling these lakes different during full glacial cycle.
