William Lonsdale

Died 11 Nov 1871 at age 77 (born 9 Sep 1794).English geologist and paleontologist whose study of coral fossils found in Devon, suggested (1837) certain of them were intermediate between those typical of the older Silurian System (408 to 438 million years old) and those of the later Carboniferous System (286 to 360 million years old). Geologists Roderick Murchison and Adam Sedgwick agreed. They named (1839) this new geologic system after its locale—the Devonian System. Lonsdale's early career was as an army officer (1812-15) and later he became curator and librarian of the Geological Society of London (1829-42). He recognised that fossils showed how species changed over time, and more primitive organisms are found in lower strata. Charles Darwin used this to support his evolution theory.«[Image: Coral-rich limestone from Petitor, Devon.]
