Coloradisaurus—a member of Massospondylidae (a group of Late Triassic long-necked sauropodomorphs or "prosauropods")—is named after the Los Colorados Formation of Argentina and has nothing to do with Colorado. Nor is it anything like Coloradia, which is what Bonaparte initially christened its remains in 1978 blissfully unaware that C.A. Blake had claimed the name for a pesky pine moth (Coloradia pandora)—a decimator of trees but a delicacy to California's Paiute people, in larvae form—115 years earlier. David Lambert spotted this error and coined Coloradisaurus as a replacement name in 1983. And it has been accepted by dinosaur experts, even though the fix occurred in the non-scientific platform of an "off the shelf" book.
Coloradisaurus fossils are scarce, but those that are known can be compared to its closest relatives to gain a rough idea of bulk and general body plan. It was about the same size as Massospondylus and shared many of its characteristics. But its most notable features are a stubby snout and huge eye sockets on the side of a relatively small skull, which led some paleontologists to muse that maybe it was an adult version of Mussaurus, which until recently was only known from juvenile specimens.
The species epithet, brevis, means "short" in Latin, and refers to its stubby snout.
