Paleozoic Era By: Sade

What is The Paleozoic Era The Paleozoic Era is time period hundreds of million years ago. The dinosaurs were alive during the Paleozoic Era.

What Animals Were Alive During The Paleozoic Era BECAUSE...Shallow seas covered most of the continents... Most of the living organisms during the Paleozoic Era consisted of oceanic life forms. Early in the era, most organisms were invertebrates. These animals looked like clams. Soft-bodied animals like sponges also lived at this time. Coral was very plentiful during this time.

Environment Plant life took a little while to take off, but in the Carboniferous period the foliage thrived. The remains of the Carboniferous plant life are what form most of today's modern coal. However, this abundance in foliage declined by the Permian period and continued past the Paleozoic era into the Triassic period.

Climate At the start of the Paleozoic era the climate was moderate and changing between stable and unstable. However, near the mid Paleozoic the climate stabilized to support all manner of land- roaming life.

Interesting Facts Did you know the Paleozoic Era had the first reptiles. It also had the first large land animals(amphibians-frogs). The Paleozoic Era also had the first insects, first large land plants, and first fish with jaws.
