"Unicerosaurus" is a nomen nuum coined by creation scientist Carl Baugh. It has never been formally described. Baugh had claimed that "Unicerosaurus" was a dinosaur, but this was rejected by Canadian geologist John R. Armstrong in a 1987 article, which identified the fossil as the neural spine of a fish. Its name derives from a mixture of Latin and Greek, Uni- "one", κερας/cera- "horn" and σαυρος/saurus "lizard". Although "Unicerosaurus" has appeared in various lists of dinosaurs, it is not considered a valid genus by mainstream paleontologists.
