Impact-extinction report
this was in this morning's San Jose Mercury News, in the Science &
Technology page. I have a feeling the story isn't accurate as to the
meeting (is it really the SVP meeting?), and I wonder what else is
right or wrong about it........
"IMPACT EXTINCTION SKEPTIC TURNS CONVERT"
A researcher has unearthed the first direct evidence of wholesale
animal die-offs after an asteroid impact 65 million years ago,
supporting the view of many scientists that the impact destroyed the
dinosaurs and other life forms. Paleontologist William Zinsmeister of
Purdue University, a leading skeptic of the "impact-extinction"
theory, said his discovery of masses of fossil fish spanning 20 square
miles-in a layer of Antartic rock corresponding precisely to the
asteroid impact-has forced him to change his mind. He will present
his findings at this week's annual meeting of the Geological Society
of America.
