Recent research found there was a global increase in mercury and warming just before the dinosaur extinction event
... [+]Nearly all dinosaurs and about 3/4 of Earth’s plant and animal species were killed about 66 million years ago during a mass extinction event.
The extinction event is associated with the impact of the Chicxulub asteroid near modern-day Merida, Mexico. However, recent research finds there was a global increase in mercury and warming before the extinction event. The asteroid impact was significant enough to mark a new geologic time period. The Cretaceous–Paleogene extinction event led to the extinction of three-quarters of plant and animal species on Earth. The asteroid impact caused an “impact winter,” where enough dust and particulates are thrown into the atmosphere that photosynthesis is severely diminished. The near halting of photosynthesis and rapid acidification of the oceans were major factors leading to widespread extinction.
The eruption of the Deccan Traps began before the impact of the Chicxulub asteroid and now with the use of geochemical isotopic analysis on mollusk shells from around the world scientists have pinpointed the eruptions to a global increase in mercury and warming from the release of carbon dioxide....
