LECTURE:

The Cretaceous-Tertiary Mass Extinction: What Really Killed the Dinosaurs?
Published on Mar 18, 2015

About 66 million years ago, 70 percent of all the species that existed at the time, including the non-avian dinosaurs, became extinct in an apocalypse widely thought to have been caused by a meteor or comet impact on Mexico’s Yucatán Peninsula.

At approximately the same time, a series of volcanic eruptions in Western India produced torrents of lava that discharged large amounts of carbon dioxide and sulfur gas into the atmosphere. Mark Richards reviews these remarkable events and explains a radical new theory suggesting they may be causally related. He also discusses how ongoing research is shedding new light on the true cause(s) of the Cretaceous-Tertiary mass extinction.

My dad told me, back in the late 50s, that the dinosaurs probably died by extreme vulcanism (pretty well read for a NYPD beat cop).

I was born and still live in NYC. And was once a geology major. Came one major-related course from completing my degree. Long story. :(

90 million years ago India rifted away from Madagascar and began its rapid movement northward, ultimately colliding with Asia between 55-50 million years ago. During the late Cretaceous (80 - 65 mya), India was moving at rates of more than 15 cm/year. No modern plate moves that fast. India's northward race towards Asia may be something of a plate tectonic speed record. The reason it moved so quickly was because it was attached to a large oceanic slab of lithosphere that was subducting beneath the southern margin of Asia

This was lubricated by a hot spot of magma that coincided with the laying down of the Deccan Traps

I just tried to click the title about Fiery world before Dinosaurs, and received a big red warning page saying there was a malware danger and I should click a square that would get me out of trouble. I did not do that I clicked the back arrow to return to the ping page. What is going on. This is the second red warning I have gotten just now at FR.

try removing the www. prefix and reloading the resulting URL, that seems to bypass the bogus malware message. The left-wing tools at Google appear to be in cahoots with the DOJ and IRS in the jackbooted campaign against conservatives and against dissent.

For the last time, I’m SURE I put out my campfire. This whole thing blew out of proportion.

That’s because smokey bears didn’t evolve until much later.

Actually, this was before dinosaurs, so my vote for the change was the development of trees and climax forests as opposed to marshes and ferns. It is generally recognized that climax forests use more CO2 than grasslands or other lower growing landscapes. I agree the Siberian traps were big, but might they have been started by a giant meteor strike?

Despite lots of searching, they've yet to find any signs of an asteroid impact coinciding with that extinction event. ie, no iridium layer, etc. Dinosaur extinction event, yes.
