It is wild to think that at one point in history, the Earth had massive great Triceratops and Sauropods thumping around, and, of course, this age has grabbed the world's interest. We yearn to learn more about these mega animals, and thanks to games like Path o...

That remains to be seen, but meanwhile a groundbreaking analysis of a 4,300-year-old accumulation of bat guano in a cave in Jamaica shows how they may have coped throughout that time. The analysis was reported in the Journal of Geophysical Research: Biogeosciences in April. The report starts by extolling the virtues of the aviating animal – no horror of the night but an ecological mainstay by eating the insects we loathe; pollinating; and dispersing seeds, explain...
Experts scooped out four-inch slices of guano from a pile more than six feet tall Biochemical markers reveal shifts in the bats' diet over thousands of years They were able to mark dry periods in 1350 BC and during the Middle Ages Chemical signatures from nuclear testing and leaded gasoline were also found The guano at the top was so wet, samples had to be taken with an eyedropper
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 cha...
Scientists dig into 4,300-year-old mound of bat poop Dan Avery For Dailymail.com © Provided by Daily Mail MailOnline logo Scientists have drilled ice cores to analyze environmental changes for decades, but now the technique is being applied to a less appealing medium: Bat poop. 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 ...
