Re: Cretaceous angiosperms

["Ken Kinman" <kinman@hotmail.com>]

   I think the oldest is Archaefructus from China, which is about 120-140 
million years old.  It's the fossil of an actual plant (not pollen).  I 
think there are some claims of pre-Cretaceous angiosperm pollen, but they 
are controversial.
