The Paleozoic Era begins after the Pre-Cambrian about 297 million years ago and ends with the start of the Mesozoic period about 250 million years ago. Each major era on the Geologic Time Scale has been further broken down into periods that are defined by the type of life that evolved during that span of time.

These 300 million years of the Paleozoic era realized many critical events in evolution, including the development of most invertebrate groups, life’s conquest of land, the evolution of fish, reptiles, insects, and vascular plants, the formation of the supercontinent of Pangea.

The Paleozoic is an ERA which is made up of 6 periods: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. Over this 291 million year period, there was a great diversity in fungi, plants, and animals. The first half was dominated by marine algae, plants, fish, tetrapods, and insects.

The Paleozoic Era is one of the most important geological divisions of our planet’s geochronological timescale, as it marks the extensive evolution of life, along with the largest mass extinction.

Paleozoic Era: Life Two great animal faunas dominated the seas during the Paleozoic. The "Cambrian fauna" typified the Cambrian oceans; although members of most phyla were present during the Cambrian, the seas were dominated by trilobites, inarticulate brachiopods, monoplacophoran molluscs, hyolithids, "small shelly fossils" of uncertain systematic posiiton, and archaeocyathids.

The Paleozoic era was an age where Earth’s diversity is believed to have greatly multiplied, with ocean animals coming out onto land. Massive forests with primitive plants dominated the earth’s.
