named Coloradia, it was later discovered that the
genus name had
already been assigned to a type of moth, hence the revision and
change to Coloradisaurus in 1983. Identified as
sauropodomorph, Coloradisaurus has been
considered as a synonym to
the genus Mussaurus.
However, Mussaurus has been established only
upon hatchlings, it will be impossible to be certain of this without
the discovery of more individuals of different ages that show the
transition from juvenile to adult individuals.
Coloradisaurus is named after the Los Colorados Formation where the holotype fossil was discovered, other dinosaurs from this formation include Riojasaurus, Lessemsaurus and Zupaysaurus, the latter of which might have been a predator of Coloradisaurus.
