Erik Jarvik
Anders Erik Vilhelm Jarvik (30 November 1907 – January 11, 1998) was a Swedish palaeozoologist who worked extensively on the sarcopterygian (or lobe-finned) fish ''Eusthenopteron''. In a career that spanned some 60 years, Jarvik produced some of the most detailed anatomical work on this fish, making it arguably the best known fossil vertebrate.
Jarvik was born at a farm in Utby Parish near Mariestad in northern Västergötland. He studied botany, zoology, geology, and paleontology at Uppsala University, where he took his licentiate's degree in 1937. In 1942, he completed his PhD with the dissertation ''On the structure of the snout of Crossopterygians and lower Gnathostomes in general''. He participated in the Greenland expedition of Gunnar Säve-Söderbergh in 1932 and was appointed assistant in the Department of Palaeozoology of the Swedish Museum of Natural History in Stockholm in 1937; he eventually succeeded Erik Stensiö as professor and head of the department in 1960, retiring in 1972.
==Research==
Jarvik's research concerned mainly the sarcopterygian fishes. His main interests were in the so-called "rhipidistian" sarcopterygian fishes, which he held to be divided into two groups: the Osteolepiformes and the Porolepiformes.〔Jarvik, E. (1942). On the structure of the snout of crossopterygians and lower gnathostomes in general. ''Zoologiska Bidrag från Uppsala, 21,'' 235-675.〕 He published several solidly descriptive works on Devonian sarcopterygians.〔Jarvik, E. (1937).
