Coloradisaurus (meaning “Los Colorados lizard”) is an genus belonging to massospondylid sauropodomorph dinosaurs. It was a resident of its Late Triassic period (Norian stage) in the present La Rioja Province, Argentina. It was identified from two specimens found in the Los Colorados Formation of the Ischigualasto-Villa Union Basin.

The Holotype from Coloradisaurus (PVL 3967) is a nearly full skull, which is paired with an unidentified skeleton. The left side of the skull appears preserved with nearly all bones present however, the left side is deformed and lacking bones. The holotype specimen is believed to be 3 meters (10 feet) in length and weighed a total of 70 kilograms (150 pounds). A related to specimen (PVL 195904) is an incomplete skeleton that includes majority of the dorsal vertebrae as well as parts of the pelvic and pectoral girdles as well as legs. The whole thing was discovered in the year 1971 in the La Esquina locality in the upper part of the Los Colorados Formation near Pagancillo, La Rioja Province, Argentina. Its top part of Los Colorados Formation has been recorded as 213 Ma this would place Coloradisaurus within the Norian stage of the Late Triassic.
