The '''Cambrian''' [[period (geology)|period]] is part of the [[geologic system]] of classifying geologic formations.

The Cambrian period is the first period of the [[Paleozoic]] era, and is divided into Early, Middle, and Furongian epochs.  The Cambrian is preceded by the [[Precambrian]] era and followed by the [[Ordovician]] era.

Under the uniformitarian dates assigned by secular geologists, it represents approximately the period of Earth's history from about 542 million years ago to 488 million years ago.<ref>Gradstein, F.M., and Ogg, J.G.,[http://www.stratigraphy.org/scale04.pdf Geologic Time Scale 2004 – Why, How, and Where Next!]</ref>  Young Earth creationists reject the uniformitarian assumptions behind the dates derived by secular geologists, so they reject these dates (see [[geologic system]]).  Instead, most would consider the Cambrian sediment to be early [[Flood Geology|Flood]] deposits.<ref>Snelling, Andrew, ''Radiohalos in Granite'', chapter 5 of DeYoung, Don, "Thousands, Not Billions", Master Books, 2005, p.89, ISBN 0-89051-441-0.</ref>

Evolutionists believe that the [[Cambrian Radiation]] gave rise to almost all living phyla, but often in extinct forms with small resemblance to typical living species. Common Cambrian [[fossil]]s 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 what are considered to be the first [[vertebrate]]s, "primitive" jawless fish.

Fossil remains other than shells or carapaces are rare, leading evolutionists to conclude that many of the organisms of the Cambrian were soft-bodied [[invertebrate]]s.  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>
