"For a long time, people didn't really start to believe that asteroids could really hit the Earth and make a noticeable impression until the discovery of Meteor Crater. In fact, evidence proved that it had to have resulted from an asteroid impact. A scientist named Eugene Shoemaker found shocked quartz at the bottom of the crater and it's only possible to get this particular kind of glass with extremely high temperatures and pressures generated in an extremely short amount of time." -- Amy Mainzer, astronomer, March 4th 2008
Here's another idiotic mainstream article that totally ignores catastrophic meteorite impact events but at least there is one paragraph that makes sense.
Science Daily: Humans Caused Demise of Australia's Megafauna, Evidence Shows.
But one site in western NSW -- Cuddie Springs -- stood out as an anomaly. Fossils of super-sized kangaroos, giant birds and the rhino-sized Diprotodon (the largest marsupial ever to roam Australia) were found in the same sedimentary layers as stone tools, leading some scientists to previously claim "unequivocal evidence" of a long overlap of humans and megafauna.
