I'm pretty sure this was already common knowledge.

Yeah, although, it has been and indeed still is, just a theory, but the evidence is becoming more clear. For instance this new analysis has ruled out a number of competing theories. It is another step along the scientific process I guess.

This is a better article I think: BBC News - Dinosaur Extinction (http://news.bbc.co.uk/1/hi/sci/tech/8550504.stm)


They reached the consensus after conducting the most wide-ranging analysis yet of the evidence.

Writing in Science journal, they rule out alternative theories such as large-scale volcanism.

The analysis has been discussed at the 41st Lunar and Planetary Science Conference (LPSC) in the US.

A panel of 41 international experts reviewed 20 years' worth of research to determine the cause of the Cretaceous-Tertiary (K-T) mass extinction, around 65 million years ago.

The extinction wiped out more than half of all species on the planet, including the dinosaurs, bird-like pterosaurs and large marine reptiles, clearing the way for mammals to become the dominant species on Earth.
