Arkell (June 9, 1904 - April 18, 1958) was an English paleontologist who was an authority on Jurassic ammonites and their environments. He wrote Jurassic Geology of the World (1956), which critically reviewed the information dispersed throughout the world's enormous literature on the world's Jurassic stratigraphy.
He made numerous contributions to knowledge of the Jurassic stratigraphy, and gradually stabilized many stratigraphically significant zonal assemblages. In 1946, his "Standard of the European Jurassic" advocated a commission formulate a code of rules for stratigraphical nomenclature. image From Today In Science History:
