I thought Alvarez had basically strong-armed everyone into accepting his theory...but I recall hearing about the Deccan alternative more than 10 years ago.
Alvarez found a thin layer of iridium at the level of the die-offs. Is that consistent with the Deccan incidents?
I thought Alvarez had basically strong-armed everyone into accepting his theory...but I recall hearing about the Deccan alternative more than 10 years ago.Dewey McLean claimed that Alvarez threatened him, which isn't what happened. McLean though felt so much pressure that he had some nerve problems. Apparently he was viewed as being a washed-up old has-been / never-was by some of his academic colleagues at his university workplace. Anyway, he retired or semi-retired, and built a website in which he kept harping on A) the claim that the extinctions were gradual, B) that the extinctions were already taking place when the impact happened, C) that the extinctions may not have been so gradual after all, and D) that volcanism was the main cause of the dinos' end.
