Charles Lapworth

Born 30 Sep 1842; died 13 Mar 1920 at age 77. English geologist who proposed what came to be called the Ordovician period (505 to 438 million years old) of geologic strata. Lapworth is famous for his work with marine fossils called graptolites. By fastidiously collecting the tiny, colonial sea creatures, he figured out the original order of layered rocks that had been faulted and folded in England's Southern Uplands. This method of correlating rocks with graptolites became a model for similar research throughout the world. In 1879, Lapworth proposed a new classification of Lower Paleozoic rocks with the Ordovician, between the redefined Cambrian and Silurian periods, Lapworth convincingly settled a heated dispute. The name comes from an ancient Welsh tribe, the Ordovices.
