Before Cambrian rocks became a chapter in every geology textbook, Cambrian was simply a grand Latin label for Wales. The Romans appear to have reshaped the Welsh self-name Cymry, linked to Old Celtic Combroges, “compatriots,” into Cambria. That name then traveled through medieval geographical writing and, according to one account, French cambrien before settling into English. In 1836, geologists began using it for rocks first studied in Wales and Cumberland, turning a name for a people and landscape into the label for Earth’s first Paleozoic period. The period lasted roughly 52 million years—from 538.8 to 486.85 million years ago—and witnessed the famous Cambrian explosion of animal life. So when you say Cambrian, you are quietly invoking both “fellow countrymen” and an ancient seafloor crowded with creatures testing out shells, legs, and eyes for the first time.
