Geological Time - Permian Period

Still Under Construction - Please check back for geotime site navigation

The Permian Period, 290-245 million years ago, marked the end of the Paleozoic Era. By this time, plant and animal Kingdoms had evolved into things we recognize today. The land masses had converged into a single great continent called Pangea. The Permian Period came to a close when a gigantic meteor impact caused the sudden extinction of the trilobites and many other invertebrates.
