Gas may be to blame for extinction
Contrarian theory argues against meteorite killing dinosaurs.
DENVER, COLORADO
A worldwide burp of volcanic gases caused the mass extinction that wiped out dinosaurs and other creatures 65 million years ago, says research reported this week. It’s the latest argument from a group that has been trying for some time to discredit the leading theory — that a meteorite striking Mexico led to the mass die-offs.

Nice work. It gives new angle to the mass extinction that happened 65 million years ago. There is lot of hopes to get more promising discovery from this.
nice work, great science: Chixculub or Chicxulub, who cares. A few 100 000 years up or down means nothing. Al Gore is happy: it was a climate catastrophy! happy hole drilling!
So it looks as if the two events competing or the the accolade of removing the dinosaurs may have occurred simultaneously. I wonder whether there is a connection. I recall reading that the main effect of a large impactor on the earth crust was on the side of the earth opposite to the impact. Where was India relative to Mexico at the K/T boundary? Geologists; help please. I liked Anton Schober's comment. I suspect that the dinosaurs were as powerless in preventing their climate change as we are ours.
