| - The Ordovician period was a time period in Earth's history, following the Cambrian and preceding the Silurian.
- While recognition of the distinct Ordovician period was slow in the United Kingdom, other areas of the world accepted it quickly. It received international sanction in 1906, when it was adopted as an official period of the Paleozoic era by the International Geological Congress.
- The Ordovician was a period in Earth's history. Although nearly all of life in Ordovician was underwater, some arthropods like the eurypterids ventured onto land, mainly to mate. Ordovician atmosphere was unlike today's air. There was much more carbon dioxide present in the atmosphere back then than today. If a human visited the Ordovician without special breathing apparatus, they would experience headaches and nausea.
- The Ordovician period is the second of the six (seven in North America) periods of the Paleozoic era. It follows the Cambrian period and is followed by the Silurian period. The Ordovician, named after the Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879, to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same rock beds in northern Wales into the Cambrian and Silurian periods respectively. Lapworth, recognizing that the fossil fauna in the disputed strata were different from those of either the Cambrian or the Silurian periods, realized that they should be placed in a period of their own.
