75% of all living things died but ALL of the dinosaurs died? Clouds of sulphide, which is about .03% of Earths crust, along with carbon dioxide caused a nuclear winter? Really? A trace element can do that? And the carbon dioxide? Where did it come from? Isnt it interesting? Wizards cant tell where the covid19 came from a couple of months ago but want me to believe that they can tell what happened 66 million years ago?
All large species perished. Small birds and mammals managed to survive. Birds are technically dinosaurs, so the dinos really did not quite die out.
All dinosaurs did not die. They are even still all around us, you see them every day, in fact.
So called accepted science today is a farce. The massive amount of dust in the stratosphere is what likely cooled the planet.
It's also very likely a large sun flare, Sungrazing comet, near by star Nova debris or comet hitting/blowing up on entry is what ended the glaciation
