View Full Version : Chicxulub Crater core samples

"The effort to drill into the Chicxulub Crater off the coast of Mexico has been declared an outstanding success."

I'm really looking forward to the information from this project!

What took them so long to do this?

and I am so happy.

Same old problem lack of project/funds IMO

And yes Jeff, despite your incredulity several sources state that the impact heated the atmosphere of the Western Hemisphere to 350F for over three hours.

Do we have any weather models for that? I've only ever seen the "nuclear winter" scenarios.

Which, I'm sure, led to an interesting hurricane season that year. The impact happened in June BTW. Fossilized pollen says so. The impactor came in from the south and was large and fast enough it didn't get pulled straight down by gravity, but hit at an oblique angle that emptied the Caribbean into Texas. That tsunami flowed 180 miles inland washing 5000 ton blocks of basalt inland with it.

Caves good then when impact looms!

(Let me adjust my tin-foil hat here.)

Which is why I think, after specialized termite eating dinosaurs were found out, that the cupracabra is a surviving, nocturnal, cave dwelling theropod that was a vampire, like some South American bats.

Now why they didn't starve out like the other theropods I can't fathom.

BBC has an article on this. Scientists have begun examining the cores from the drilling. It makes sense, but I had no idea about 'disaster species'. My paleontology class left that out, I guess.

"We've been able to examine that first 10,000 years after the impact, which is dominated by what we call 'disaster species' - dominated by the organisms that love stressed environments. And then we can see evolution coming back in [during] the next few hundred thousands years after that," he told BBC News.

Another interesting article - Ok, the headline is lame, but the article is pretty good.
"Scientists say they can now describe in detail how the asteroid that wiped out the dinosaurs produced its huge crater."

BBC had a mini series one of which covered the impact. One of many theories as to what happened.
