Scientists digging into the dinosaur-killing asteroid crater answer all your questions

A team of researchers is investigating the Chicxulub crater, of the asteroid that wiped the dinosaurs (and many other creatures) some 65,5 million years ago. Now, they’ve set out to Reddit to answer all our questions. Sean Gulick from the University of Texas Institute for Geophysics (UTIG) and Joanna Morgan from the Imperial College London as well as postdoctoral fellow Chris Lowery have been drilling in the crater since April 14 and will spend approximately two months at sea retrieving rock cores before returning to their respective institutions to study the samples. These are some of their most interesting answers.
Firstly, a comment:
Not a direct reply to anyone’s question, but I’m just going to leave this here:
It’s a little old (you’ll notice that they have the boundary at 65 when we now have it at 66 million years ago), but it’s probably my favorite poster because it shows 1) how the microfossils that I study, which are called foraminifera, changed across the boundary (~90% of the ones that live in the upper water column went extinct), and 2) what the KPg Boundary looks like in deep sea sites, in this case from ODP Leg 171B from off the Atlantic coast of Florida.
Then the questions:
Q:After the impact, how quickly (or slowly) did it kill the dinosaurs? How did it kill them (most interested about those that didn’t die quickly)? What other animal and plant life was lost? How big of a percentage of animal and plant life was lost?
Andrei's background is in geophysics, and he's been fascinated by it ever since he was a child. Feeling that there is a gap between scientists and the general audience, he started ZME Science -- and the results are what you see today.
