The '''Cambrian''' period was the first period of the [[Paleozoic]] era. Following on from the [[Pre-Cambrian]], it lasted from approximately 543 million years to about 490 million years ago. It was followed by the [[Ordovician]] period. The Cambrian was named by the geologist Adam Sedgwick for Cambria,<ref>http://www.ucmp.berkeley.edu/history/sedgwick.html</ref> Latin for [[Wales]], which has large areas of rock originating in, and characteristic of, the period.
The [[Cambrian Radiation]] gave rise to almost all living phyla, but often in extinct forms with small resemblance to typical living species. Common Cambrian fossils are of [[trilobite]]s, and inarticulate [[brachiopod]]s,<ref>http://www.palaeos.com/Paleozoic/Cambrian/Cambrian.htm#bio</ref> [[coral]]s and primitive [[echinoderm]]s. They also include the first vertebrates, primitive jawless fish.
Since many of the organisms of the Cambrian were soft-bodied invertebrates, fossil remains other than shells or carapaces are rare; one notable site for soft-bodied Cambrian invertebrate remains is the [[Burgess Shale]] of [[British Columbia]].<ref>http://wwwalt.uni-wuerzburg.de/palaeontologie/Stuff/casu9.htm</ref>
