The asteroid that extinguished dinosaurs turned oceans into acid, says a shocking study
A recent study shows that the asteroid that triggered the dinosaurs also acidified the oceans of the earth.
The research looks at newly discovered evidence from fossilized algae, known millions of years ago as foraminifera. The experts analyzed the chemical element boron to show in detail how devastating the asteroid impact was, hoping to end the debate that led other natural disasters – such as a massive volcanic eruption – to the death of the dinosaurs.
The increase in ocean acidification, an event that would take "millions of years" to recover until the oceans and the planet recover, was devastating, experts said. "Our data suggest that the impact rather than volcanism contributed significantly to the extinction of the Cretaceous," the study's summary states. (Source: SWNS) “/>

MINUTES REPORTS ON THE EXCEPTIONAL EXCEPTIONAL EARTH OF DINOSAURS
in a statement.
The scientists examined clay samples from an underground cave in the Netherlands for their investigations. This cave contained "a particularly thick layer of clay immediately after impact," Henehan said, adding that it was "really rare."
The picture shows the border between the Cretaceous and the Paleogene in the Dutch town of Geulhemmerberg, where the border sound samples were taken. The event bed is clearly visible as a gray clay-rich layer between the otherwise yellowish carbonate sediments. It was assumed to have been deposited in calm periods between strong storm events.

The newly discovered results seem to be some of the most definitive evidence of dinosaur extinction and how fast it happened when sulfur gas poured into the atmosphere and eventually caused acid rain.
"Our data argue against a gradual deterioration in environmental conditions 66 million years ago," added Henehan.
The find is also the first direct link between the extinction of dinosaurs and a sharp increase in the pH of the oceans, Henehan continued.
"For years it has been suggested that the pH of the ocean has dropped because the meteor impact hit sulfur-rich rocks and caused the outpouring of sulfuric acid, but so far there was no direct evidence that this happened."
