The Cambrian Period was followed, million years ago, by the Ordovician Period. At that time many species died out, to be replaced by new ones in another evolutionary “explosion”, called the Great Ordovician Biodiversification Event (or GOBE). During the Ordovician, the seas surrounding North America and Europe became rich in life, especially trilobites, brachiopods and reef . Silurian Period, in geologic time, the third period of the Paleozoic Era. It began million years ago and ended million years ago, extending from the close of the Ordovician Period to the beginning of the Devonian Period. During the Silurian, continental elevations were generally much. Crinoids survived the cataclysmic extinctions that mark major geologic eras, including the great Permian extinction of million years ago, which wiped out practically everything (perhaps Silurian Period. The Silurian was the third division of the Paleozoic era of the geologic time scale spanning from approximately and million years ago, preceded by the Ordovician and followed by the ck Impey Murchison, a Scotsman, who eventually became the director of the Geological Survey of Great Britain, was responsible for naming the period.

biota that helped to form the reefs. Among the least understood Silurian reef contributors are the echinoderms, in particular the crinoids. Little research has been done on Silurian reef crinoids; the last major work was in This is in part due to the high dolomitization of the fossils that makes identification of these species more difficult.
