Well, whaddaya know. I thought the cause of dinosaur extinction was still up in the air: meteor? ice age? mass suicide pact? Well, I guess I don’t keep up on my crater news, as there’s a consensus now: meteor. In 2010, 41 experts came to a consensus that whatever nasty meteor caused the massive 180km in diameter Chicxulub crater turned the lights out on dino time. Good to know!
