The correct authorship of Coloradisaurus (Dinosauria, Sauropodomorpha): Galton, 1990, not Lambert, 1983

Until now, authorship of the sauropodomorph dinosaur genus Coloradisaurus has been attributed to Lambert, 1983. Here we demonstrate that Lambert's work does not meet the requirements of Articles 13.1 and 13.3 of the Code for availability of this name, therefore it is a nomen nudum in that publication. Instead, it was inadvertently made available a few years later by another worker, as ColoradisaurusGalton, 1990.
