Silurian Period
Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the middle part of the Silurian Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.
Scottish geologist Roderick I. Murchison began his study of the rocks he later named the Silurian System in 1831. He conducted this research in South Wales and the border region between Wales and England.1
He named the sequence after the Silures, an ancient native people who inhabited that region and resisted Roman conquest. Murchison formally detailed these findings in his 1839 work, The Silurian System.1
