[meteorite-list] K-T Impact

[Sterling K. Webb]

List,

A producer of radio shows which are often 
heard on various NPR stations, Radiolab.org, 
has toured a live stage show presentation on 
the K-T extinction. I heard it by accident 
and was entertained and informed (that's the 
whole idea, isn't it?).

It has interviews with Jay Melosh and other 
impact scientists (recorded and integrated 
into the live presentation). I recommend it 
if impact extinction is your thing. Luckily,
there's a YouTube:

(Isn't there a YouTube of everything?)

The show is called, appropriately enough,
"Apocalyptical." The above link is to just 
that portion that deals with the impact and 
the "Dinopocalypse," but all portions and 
smaller selections can be linked to from 
this page:

After all, there aren't too many stage 
shows based on the K-T impact and dino 
extinction!

They (or rather their recorded scientist 
guests) attribute the K-T impactor to the 
breakup of the Baptistina Family, but recent 
(2011) studies based on WISE (Wide-field 
Infrared Survey Explorer) data claim to 
blow the Baptistina theory out of the water 
(so to speak) or out of the sky or whatever.

"As a result of the WISE science team's 
investigation, the demise of the dinosaurs 
remains in the cold case files..."

The apparently as-yet-unpublished 2008 paper, 
"New Constraints on the Asteroid 298 Baptistina, 
the Alleged Family Member of the K/T Impactor,"
by Daniel J. Majaess, David Higgins, Larry A. 
Molnar, Melissa J. Haegert, David J. Lane, 
David G. Turner, and Inga Nielsen can be 
found at:

A more "popular" explanation of the ruling out 
of the Baptistina Family can be found at:

But the stage-show YouTube is definitely 
worth watching. Catch it.
