The Cambrian explosion is an apparently sudden increase in fossils marking the separation between Precambrian rocks and Cambrian rocks. At one time this was believed to mark the beginning of multicellular life, but in fact it only marks the evolution of hard body parts (most of which were made of calcium carbonate). It turns out that there were as many multicellular organisms in the late Precambrian as there were during the Cambrian explosion at the beginning of the Cambrian, but the lack of hard body parts in those organisms made the formation of easy to identify fossils of those organisms much rarer.
