90480 Ulrich           Discovered 2004 Feb. 15 by the Catalina Sky Survey.
Carl Ulrich (b. 1925) is a fossil preparator, known for his work on the fossils of the Green River Formation of Wyoming. He has instructed hundreds of people in his preparation techniques. His fossils can be seen in museums worldwide and at his gallery just outside the southern boundary of Fossil Butte National Monument.
