The Chicxulub Crater Was Created 66 Million Years Ago When A Large Asteroid Struck Earth And Killed The Dinosaurs, But Recent Rock Samples Suggest The Impact Didn’t Release As Much Carbon Dioxide As Initially Thought

If that really did happen, then less carbon dioxide entered the atmosphere than originally thought because much of it would have been quickly reused for calcium carbonate.

With a reduced amount of carbon dioxide in the atmosphere during the mass extinction event, the effects of global warming and ocean acidification would not have been as extreme.

Overall, the paleothermometer has helped shed light on the circumstances that unfolded 66 million years ago.

It can also be applied to impact craters in other parts of the world, providing new opportunities to gain more knowledge about asteroid collisions.
