Jacques Gauthier

from Wikipedia, the free encyclopedia

Jacques Armand Gauthier (* 1948 ) is an American zoologist and vertebrate paleontologist. He is one of the founders of cladistics in paleontology.

Gauthier studied zoology at San Diego State University with a bachelor's degree in 1973 and a master's degree in 1980 (on the systematics of the sneaky ) and received his doctorate in paleontology in 1984 from the University of California, Berkeley (A cladistic analysis of the higher systematic categories of the Diapsida). In his dissertation he undertook a cladistic analysis of the Diapsids . He is professor of geology and evolutionary biology at Yale University and the Peabody Museum of Natural History as curator of vertebrate zoology and paleontology.

In 1986 he introduced the ornithodira , argued for the monophyly of dinosaurs and for the ancestry of birds from theropods . This was also the beginning of a new cladistic system of the dinosaurs and reptiles. Further work concerned the cladistic systematics of the Amniotes , Squamata and Lepidosauria .
