John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American paleontologist who revolutionized modern understanding of dinosaurs in the 1960s. Ostrom showed that dinosaurs were more like big non-flying birds than they were like lizards (or "saurians") as first proposed by Thomas Henry Huxley in the 1860s.〔Fedduccia, Alan 1999. ''The origin and evolution of birds''. Yale University Press, p55. ISBN 0-300-07861-7〕〔Heilmann G. 1926. ''The origin of birds''. London: Witherby.〕 The first of Ostrom's broad-based reviews of the osteology and phylogeny of the primitive bird ''Archaeopteryx'' appeared in 1976. His reaction to the eventual discovery of feathered dinosaurs in China, after years of acrimonious debate, was bittersweet.〔(At last, his theory flies ). May 5, 2000. Olivia F. Gentile. ''Hartford Courant''.〕 == Early life and career == He was born in New York and studied at Union College. He planned to be a physician like his father, but changed his mind after reading George Gaylord Simpson's book ''The Meaning of Evolution''. He enrolled at Columbia University and studied with Edwin H. Colbert. In 1952 he married Nancy Grace Hartman (d. 2003) and he had two daughters: Karen and Alicia. Ostrom taught for one year at Brooklyn College and then spent five years at Beloit College before going to Yale. Ostrom was a professor at Yale University where he was the Curator Emeritus of vertebrate paleontology at the Peabody Museum of Natural History, which has an impressive fossil collection originally started by Othniel Charles Marsh. He died from complications of Alzheimer's disease at the age of 77 in Litchfield, Connecticut. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Ostrom」の詳細全文を読む スポンサード リンク
