Eon / Era / Period / Epoch
What happened during this time?
Biological
Flora, spore-bearing
Scale trees, such as Sigillaria, are still around but decreasing in prominence
Extant clubmoss groups, such as the Lycopodiales and Selaginellales are found in the understory of some forests
Marattialean tree ferns and smaller zygopterid ferns still exist, but becoming less prominent
Sphenophyllophytes are found in the under-story, and horsetails along rivers and wetlands
True ferns are beginning to appear on the landscape
Noeggerathian progymnosperms are still present, but not as dominant as before
Flora, seed-bearing
Cordaites start to dominate in Euramerica
Glossopterids start to dominate in Gondwana
Cycads may have been present, but there is debate on the earliest known member of this group
Giganopterids were among the most striking and important plants of the Cathaysian flora of Sino-Malaya (Wang 1999)
Seed ferns, such as the medullosids, callistophytes, and peltasperms were still on the landscape; the former becoming much less prominent
