The Permian Period,248 million years ago, was the largest extinction period on Earth. Ninety to ninety-five percent of marine species were eliminated, including fusulinid foraminifera, trilobites, rugose and tabulate corals, blastoids, acanthodians, placoderms, and pelycosaurs. Numbers of sharks and bony fish were drastically reduced during this period.
Some of the major events are listed below: 4.6 billion years ago-mercury born 1974-Mariner 10 maps 40% of its surface 2008-Messenger maps most of the planet.
Severe defeat for the Germans at Stalingrad (Jan-Feb)Warsaw Ghetto Uprising.Italy surrendered.
The Carboniferous (Mississippian & Pennsylvanian) was not known for megafauna. There were some pretty big insects at that time. Diplovertebron reached lengths of nearly 2 feet. It was amphibious, dining on fish and smaller amphibians. Archaeothyris also reached lengths of nearly 2 feet, and was a synapsid (a precursor to modern mammals). From its teeth it is presumed to have been carnivorous.Edaphosaurus was a late carboniferous synapsid that lived into the Permian. It grew up to 12 feet long, but it was an herbivore, not a carnivore.The size and variety of carnivores increased substantially by the Permian.
The end of the Silurian period and the beginning of the Devonian period was not defined by an extinction event, but by the distinctive rock formations of the period. As a result the end of the Silurian period is uncertain by +/- 2.8 million years.
Some of the major geologic events include ice ages, the formation of the great lakes, and the continents moving to where they are now.

Major events in mountains and basins typically include the formation of the landscape through processes like tectonic plate movement, erosion, and volcanic activity. Other important events can include the creation of habitats for diverse flora and fauna, interactions between different geological layers, and the impact of human activity on these unique ecosystems.
Some major international events during this period include World War II (1939-1945), the signing of the United Nations Charter in 1945, the partition of India and Pakistan in 1947, the establishment of NATO in 1949, and the beginning of the Korean War in 1950.
