4,300 Years of Bat Poop From The Depths of a Jamaican Cave Have Revealed Earth s Past

4,300 Years of Bat Poop From The Depths of a Jamaican Cave Have Revealed Earth s Past 14 APRIL 2021 You may not give a pile of bat poop gathered over 4,300 years a second look – but to a group of scientists, it s provided an intriguing insight into how bat diets and therefore climate conditions have shifted over thousands of years. Taller than the average man (2 meters or 6-and-a-half feet), the pile of poop (also known as guano) records history in clear layers, much like sediments under a lake. By analyzing the layers back through time, the scientists have been able to figure out changes in the diets of the bats that have been inhabiting this cave for millennia.

Researchers discovered a veritable mountain of guano deep in a cave in Jamaica, deposited over the course of 4,300 years. Left largely undisturbed, the pile stands more than six feet tall. Analysis of undigested material in the dung paints a timeline of everything from dry periods in the Middle Ages to the arrival of Christopher Columbus and the advent of the gas-powered engine.

Your support of our work is inspiring and invaluable. Fifty Years Ago, at Lake Mungo, the True Scale of Aboriginal Australians’ Epic Story Was Revealed Australia’s deep history was uncovered at Lake Mungo. This month marks the golden jubilee of a watershed event in the history of this nation that should cause all Australians to pause and reflect. On July 15, 1968, while searching for clues to past climates and ancient landscapes on land under the joint care of Paakantyi/Barkindji, Ngiyampaa and Mutthi Mutthi people, Earth scientist Jim Bowler ambled across the cremated remains of an Aboriginal woman eroding from a crescent-shaped dune flanking the shoreline of now-dry Lake Mungo in western New South Wales.
