Taxacom: "Early Permian" angiosperms... real or not real taxa/names?

Thu Jun 2 18:12:07 CDT 2022

Hi Michael, yes but unless I am mistaken, these are only hypothetical dates
based on suggestions from molecular evidence. So far as I am aware there
are still no "accepted" pre-Cretaceous angiosperm fossils. Were
Mr/Dr Wachtler's "Early Permian angiosperms" to be authenticated by other
workers the results would be a paleobotanical sensation, which is I suspect
why they have been published outside the mainstream literature, more than
likely without peer review...

I still wonder what it is he is describing, though...
