| Ultrasaurus is a name given in 1985 to a sauropod, probably a brachiosaurid, from the Morrison Formation of Colorado. However, the same name was given earlier, in 1983, to a South Korean sauropod, and the earier usage takes precedence. The name of the Colorado specimen was later changed to Ultrasauros, but it remains unclear whether this represents a valid taxon. | ||||||||||||||||||||||||||||||
