A New Timeline of the Day the Dinosaurs Began to Die Out

By drilling into the Chicxulub crater, scientists assembled a record of what happened just after the asteroid impact.

Consider the Earth’s history as the old measure of the English yard,
the distance from the King’s nose to the tip of his outstretched hand.
One stroke of a nail file on his middle finger
erases human history.

The Dinosaur-Killing Asteroid Acidified the Ocean in a Flash

The Chicxulub event was as damaging to life in the oceans as it was to creatures on land, a study shows.

Dinosaurs: The Final Day with Sir David Attenborough will be broadcast on BBC One on 15 April at 18:30 BST.
A version has been made for the US science series Nova on the PBS network to be broadcast later in the year.

I watched both NOVA episodes last night - New Evidence and The Final Day. I thought they were very well done.

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience."

-- C.S. Lewis
