Earliest Marine Life recorded. Abundant amount of Trilobites.

This is where the inverterbrates animals which replaced.
-
The high sea levels and warm shallow continental seas provided a hospitable environment for marine life of all kinds. The biota and ecological dynamics were basically still similar to that of the Ordovician, but was more diverse.
-
Sea ammonids and fish evolve and quickly diversify. On land trees and forests appear for the first time. The first insects, spiders, and tetrapods evolve.
-
These ancient continents were destined to drift together and collide, forming the supercontinent of Pangaea during the Permian Period. Major continents of the Carboniferous included Gondwana, Laurentia, Baltica, and Siberia. Gondwana was the largest land mass, comprising what would later fragment to become modern South America, Africa, India, Australia, New Zealand, and Antarctica. This massive continent lay entirely within the southern hemisphere, covering a vast area including the South Pole.

Permian rocks contain a rich fossil record. On land, seed ferns were joined by conifers and ginkgos as important members of the flora. Amphibians were declining in number, but reptiles, which had appeared in the preceding period, were undergoing a spectacular evolutionary development of carnivorous and herbivorous mammal-like forms. Also during the Permian Period the forerunners of the dinosaurs appeared. For the most part, the invertebrate marine life during the Early Permian was exceptionally
