Re: Cretaceous angiosperms



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.

Just a quick question: is the Koonwarra specimen (S.E. Australia,
115-118 MYA) still the earliest known example of a preserved angiosperm
flower? Is there any eariler evidence based on pollens?
