       Named after a demon that appears in Mapuche mythology,‭ ‬Gualicho is a medium sized genus of theropod dinosaur that lived in South America during the early stages of the late Cretaceous.‭ ‬Gualicho would have been a predator of other smaller and similarly sized dinosaurs.
       Gualicho was named as a genus in‭ ‬2016,‭ ‬and also this year a second similarly formed dinosaur from the same approximate location as Gualicho was called Aoniraptor.‭ ‬Similarities in known vertebrae fossils of these two dinosaurs have been noted,‭ ‬which has led to some suggestion that the two dinosaur genera may be synonymous.‭ ‬However the original description of Aoniraptor did not meet naming specifications outlined by the ICZN‭ (‬the international body that governs the naming of animals‭)‬,‭ ‬while the description of Gualicho did.‭ ‬For these reasons,‭ ‬Gualicho is considered to be a valid name for a genus,‭ ‬while Aoniraptor is not,‭ ‬which has led to its classification as a Nomen nudum.
