FW: World-Wide KT Boundary

["Beyer, Eric" <Eric.Beyer@cognos.com>]

I have just found the "Theories on the extinction of dinosaurs" thread 
(more like a sweater!) in the November archives.  I shall wade through 
the postings (100+) and see what I find.  

If anyone has the time to summarize I would be grateful.

I am particularly interested in the possibility of finding specimens
above the KT in different easterly locals.  If it could have been a Western 
Hemisphere event (Yucatan impact) would the result be fully felt in the 
most distant locations based on planetary winds?

I remember something about prevailing winds staying within the hemisphere 
perhaps slowing an airborne dust cloud.


Just a thought;

Much has been said, studied and written about the KT boundary and the events
that caused such a world-wide extinction.  I have a few questions that may
be juvenile but none the less will get asked...

How much is known about the KT boundary layer outside of the western
hemisphere?  
Are the findings in other parts of the world consistent with western
findings?
The KT layer has been seen to be 3 feet wide in some areas and 3 mm in
others, how much time does that layer represent?

I guess the thrust of query is knowing how many of the world-wide
catastrophe theories that are accepted today are based on world-wide data?


Direction to accessible reading material on this would be appreciated.


Cheers;
Eric
