What are the 7 mass extinctions?
In order, these extinctions are known as the Ordovician (443 million years ago), the Late Devonian (372 million years ago), the Permian (252 million years ago), the Triassic (201 million years ago) and the Cretaceous (66 million years ago).Sep 10, 2019

I was thinking about how many mass extinctions there have been already. I was thinking there have been only now the 6th that we are presently in. However, when I looked this up online they say there have already been 7 mass extinctions so I'm wondering what that is all about?
The most recent one where most big dinosaurs all died out was around 66 million years ago when a piece of Maldek (the asteroid belt) when it was a planet was blown up by a nuclear war there by our ancestors. So, many of the survivors of this war that affected Maldek (the asteroid belt) and Mars (asteroids from Maldek hitting Mars and making it mostly uninhabitable) came to earth or went back to other solar systems that they were from originally. So, until this nuclear war (whoever was fighting who we have no record now). In fact, the only reason we know it happened was a Soviet Russian Probe that checked out the asteroid belt and realized there had been a nuclear war there during the 1970s. Only this war had happened around 65 or 66 million years ago and one of the pieces of the planet Maldek killed all the larger dinosaurs. It was much worse what happened to Mars by the way from all the asteroids that hit Mars then 65 or 66 million years ago.
