Henry Fairfield Osborn (1857-1935) was an American geologist and paleontologist.. Osborn completed his studies at Princeton University where he became professor of comparative anatomy from 1883 to 1890. In 1891 he was hired jointly by Columbia University and the American Museum of Natural History, New York. He became professor of biology at Columbia University. At the AMNH he became president in 1908, serving until 1933, during which time he accumulated one of the finest fossil collections in the world. He assembled a great team of fossil hunters which included Roy Chapman Andrews, one of the prototypes of Indiana Jones, and Charles R. Knight, who made murals of dinosaurs in their habitats and sculptures. He was mentored by the famous paleontologist Edward Drinker Cope, whom he met on a fossil-hunting expedition in Wyoming. Osborn joined the US Geological Survey in 1900 and became senior vertebrate paleontologist in 1924. During his career he led many fossil-hunting expeditions into the American Southwest.His research and publication of “Titanotheres” was his largest work.
The Titanotheres are an extinct group of large-hoofed mammals that originated during the early Eocene. Titanotheres, more properly called “brontotheres,” became extinct during the middle of the Oligocene. Most were large and fed mainly on soft vegetation. Their skulls were massive and frequently adorned with large bony protuberances covered in skin that may have been used as defensive weapons against predators. The bodies were bulky with strong, pillarlike limbs. Osborn provides a systematic description of Titanotheres.
