Paleophytic
The Paleophytic begins in the late Ordovician Period with the rise of the vascular plants and continues until the Kingurian (Middle Permian), when advanced gymnosperms took over the Earth's floral niches. Unlike animals, land plants experienced no major extinctions at the end of the Permian. Rather, the land plant extinction seems to have preceded the P-T event. At the end of the Paleophytic, plants that dominated throughout the era such as Cordaites, Calamites, and Lepidodendron disappeared and were replaced by conifers and glossopterids.
