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

Thu Jun 2 16:09:57 CDT 2022

Hi Tony,

Dates for angiosperms in recent studies include:
Triassic to Late Permian (Beaulieu et al., 2015); Triassic-Permian (Zhang
et al., 2020); Triassic-Carboniferous (Salomo et al., 2017), and Permian
(Yang et al., 2020).
