Global warming, not asteroid impact, killed the dinosaurs

[w¡n9Nµ7 §£@¥€r 123]

Recent microfossil evidence casts fresh doubt as to whether an asteroid wiped out the dinosaurs, according to micropaleontologist Gerta Keller of Princeton University in Princeton, N.J., and her collaborators. Their analysis of ancient marine-dwelling microorganisms, called foraminifera, suggests that global warming caused by massive volcanism in India “led to dwarfing of all species and a gradual decrease in their diversity beginning 400,000 years prior to the mass extinction,” she says.

This analysis challenges a hypothesis formulated more than 25 years ago by geologist Walter Alvarez of the University of California, Berkeley, his father Luis, a physicist who had won the Nobel Prize, and their collaborators. They argued that a catastrophic cosmic event, often called the Chicxulub impact, on the northern Yucatan Peninsula of Mexico led to the demise of the dinosaurs.

“We now have evidence that the Chicxulub impact occurred about 300,000 years before the end of the Cretaceous and thus didn’t cause the mass extinction and, in fact, didn’t cause any species to go extinct,” Keller says...

Geologist Donald R. Prothero at the Occidental College in Los Angeles, Calif., is not surprised that new evidence leans away from the dinosaur impact extinction theory. “There is almost no further doubt among vertebrate paleontologists that birds are descended from dinosaurs,” he says. “If that is the case, then dinosaurs did not die out at the end of the Cretaceous after all. . . . Dinosaurs [as birds] are all around you!”

Yes...it's all India's fault...shame on them for all that massive volcanism.

So, the dinosaurs were at fault for the global warming? Were the gasses eminating from their fecal matter ruining the ozone? Or was it their excessive use of fossil fuels?

They farted themselves to death.

Too much curry in their diet.

i guess i'm to blame then for global warming
