     One post from HP Carpenter and everything that Guy Leahy, myself, and 
others have been trying to impress upon you about the pitfalls of 
biostratigraphy and the sensitivity of complex hypotheses that rest on single 
data points goes flying out the window? You haven't answered any of the issues 
raised by anyone else, and HP Carpenter did not even express an opinion 
regarding correlation of the Wangshi.

     If you get a chance, review the archives and look at some of the extremely 
long threads in which an author (I'd rather not name names, but there are some 
notables) has hung on tenaciously to a particular hypothesis in the face of 
overwhelming evidence. You don't want to end up looking like them...

     Just some food for thought.
