from Wikipedia, the free encyclopedia

Sir Cyril James Stubblefield , FRS, also cited by CJ Stubblefield, (born September 6, 1901 in Cambridge , † October 23, 1999 in London ) was a British geologist and paleontologist .

Life

Stubblefield studied at Chelsea Polytechnic and Royal College of Science and made his bachelor's degree in geology from Imperial College in London in 1923 . He was a demonstrator (lecturer) in geology at Imperial College for five years and received his doctorate in 1925 with a thesis on fossils from the Paleozoic of Shropshire . During this time he also worked with Oliver Bulman , with whom he was studying and with whom he was friends. From 1928 he was with the Geological Survey of Great Britain, located at the Geological Museum in London (then Museum of Practical Geology ), in the paleontology department. In 1947 he became chief paleontologist (until 1953), assistant director in 1953 and director of the museum in 1960. In 1966 he retired.

Under his aegis as museum director, the Geological Survey of Great Britain merged with the Overseas Geological Survey and the Museum of Practical Geology in the Institute of Geological Sciences (which has been called the British Geological Survey since 1984 ).

Stubblefield was particularly concerned with trilobites , where he discovered in 1926 how trilobites grow ( ontogenesis ) by forming new thoracic segments from the pygidium . In work from the 1930s, he examined the classification ( taxonomy ) (1936) and paleogeography (1939) of trilobites. A genus of trilobites ( Stubblefeldia ) and several species are named after him. Trilobites and their evolution were also the subject of its 1959 Presidential Address of the Geological Society.

He advocated the construction of a canal tunnel and was on its Franco-British supervisory committee.

In 1929 he showed the existence of two sexes (that is, two distinguishable types in each colony) in graptolite colonies. His work on the stratigraphy and paleontology of coal-bearing strata in the Carboniferous United Kingdom proved useful in finding new coal deposits.

From 1958 to 1960 he was President of the Geological Society of London and from 1960 to 1966 he headed the Geological Survey of Great Britain. He was a Fellow of the Royal Society since 1944 . In 1951 he received the Murchison Medal and in 1945 the Bigsby Medal of the Geological Society. In 1942 he received an honorary doctorate (D. Sc.) From the University of London. In 1965 he was knighted as a Knight Bachelor .

In 1967 he was President of the 6th International Congress of Carboniferous Geology and Stratigraphy. 1966 to 1971 he was President of the Palaeontographical Society. For many years he edited the trilobite section of the Zoological Record , and in 1959 he contributed to the trilobite volume of the first Treatise on Invertebrate Paleontology (edited by Raymond C. Moore ).

He had been married to Muriel Yakchee since 1932 and had two sons.
