A report from forensics

While I was in the UK in January I had lunch with a geologist who did his best to persuade me that the notion that the dinosaurs were seriously compromised by a meteor strike is one of those paradigms which emerges and quickly ossifies into an orthodoxy which nobody (but him apparently) is willing to challenge. He'd been to the Yucatán on a field trip and reported finding no conclusive evidence of a large crater there either.

Well this week the consensus against his renegade opinion took a firmer hold on the subject when, at 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, and concluded that the prime suspect has to remain a massive asteroid or comet smashing into Earth at Chicxulub on the Yucatán peninsula 65m years ago. You can read the BBC's report here...
