Re: Age of Gobi formations

["Dino Sniffer" <dinosniffer@hotmail.com>]

I'm sorry if I seem nit-picky, but after all, science requires precision and 
accuracy.  Proper terminology must be used, and certain nomenclatural rules 
must be followed.  The Sundance Formation does NOT overlay the Buckhorn 
Conglomerate, does NOT overly the Morrison Formation, and has NEVER been 
considered to be Lower Cretaceous.  It underlies and interfingers with parts 
of the LOWER Morrison Formation and has ALWAYS been considered to be Upper 
Jurassic.  Perhaps you're confusing the Sundance with the Dakota Formation 
(a marine unit that interfingers with the Cloverly Fm.)?  At any rate, there 
is no point further debating the stratigraphy of the 
Sundance-Morrison-Clovery interval and its lateral equivalents when all 
you'd need to do to settle this is to crack open a text or some papers on 
the relevant formations.  Just trying to help.

cheers,
The Sniffer
