Cambrian (comparative more Cambrian, superlative most Cambrian) (geology) Of a geologic period within the Paleozoic era; comprises lower, middle and Furongian epochs from about 542 to 490 million years ago. At this time the British Isles lay in the southern hemisphere and the Sahara was at the South Pole and subject to extensive glaciation. The period was established by Adam Sedgwick, who named it after Cambria, the Latin name for Wales, where Britain's Cambrian rocks are best exposed.
