F. V. Hayden (September 7, 1829 – December 22, 1887)	Back     Site Map
	Originally a surgeon and medical officer in the civil war, Hayden is probably most famous for his part in pushing for the Yellowstone area of North America to be made the first National Park. He was a brilliant geologist and was noted for his work in the Rocky Mountain late in the 19th century, founding the geological survey of America (fig.1.) Hayden is credited with being the first to discover dinosaur remains in North America. During an exploration of the upper Missouri River in 1854,  near the confluence with the Judith River, Hayden's party recovered a small number of teeth which in 1856 were described by Joseph Leidy as belonging to Trachodon, Troodon and Deinodon. Leidy recognised that Trachodon was a creature similar to Iguanodon.
