The Velociraptor was originally described as, “Ovoraptor”:
Earlier that year, Osborn had mentioned the animal in a popular press article, under the name “Ovoraptor djadochtari” (not to be confused with the similarly named Oviraptor ).[13] However, because the name “Ovoraptor” was not published in a scientific journal or accompanied by a formal description, it is considered a nomen nudum (‘naked name’), and the name Velociraptor retains priority.
Reading Velociraptor - Wikipedia quasi-confirms my suspicion that animal taxonomies are not as solid as scientists have told me.
