|Description: This is a global map from 1910 showing the distribution of Cambrian Period rocks. This map shows areas in which marine deposits are known, areas gained by the Sea between the beginning and close of the Cambrian Period, and areas of unknown distribution of Land and Sea (possible distribution shown by a dashed line). "Cambrian System, in geology, the name now universally employed to designate the earliest group of Paleozoic rocks which possesses a connected suite of fossils. The strata of this system rest upon the Pre–Cambrian, and are succeeded by the Ordovician system." — The Encyclopedia Britannica, 1910|
