Scientists investigating the Yucatan crater (believed to be the impact site of the asteroid that killed the dinosaurs) now suggest that the impact happened too far back in time to have caused the extinctions.

A core taken from the middle of the crater suggests an impact 300,000 years before the geological layer marking the sudden extinction of the dinosaurs. New magnetic evidence also agrees that the asteroid could not have directly killed the dinosaurs.

This leads to the belief that the mass extinction must have come about in some other manner, although it is still fully possible that the asteroid impact in the Yucatan was a contributing factor.

contributing factor lol, the fact is our science still sucks. It's obvious are carbon dating is failed, it will take some time for anyone to prove that though. The Yucatan crater "could" still be more then just a factor if the way we understand a extinction by an ice age caused by dust thrown up blocking the sun is flawed. We still haven't solved the most important questions, and lots of them aren't even scientific in nature. We just believe science is the best route to solve them.

Say it took 300,000 years in full for the process to happen? Geological worldwide events have known to take 700,000 liek the magmetic polar shift happening in 100 years. We don't even known why were late for this one, maybe it's gonna be different? Open up a gaping o-zone whole(they known it will open big enough ones), that would throw enough radiation to kill all of our children, and theirs?

Imo we don't really know anything.
