Plants invade the earth in the early Devonian. Animals, namely arthropods, come onto land 400-380 m.y.a. The first true insects show up in the early Devonian. By the late Devonian, terrestrial vertebrates. Carboniferous and Permian Extensive plant communities, mainly swamp that become huge coal deposits across the world.
Winged insects arise.
Amphibians are up in the Carboniferous, but drop in the Permian. Complete metamorphosis evolves in insects. First amniotes appear and develop mammal-like traits. Pangaea Another huge extinction, the largest so far with loss of lots of marine invertebrates. Pangaea breaks up during the Triassic.
