       Named in‭ ‬2016‭ ‬from a single specimen,‭ ‬Viavenator is another of the growing number of South American abelisaurid dinosaurs that are known to us.‭ ‬At a glance Viavenator does not seem to be anything special apart from being another abelisaur,‭ ‬however the authors of the paper describing this dinosaur have identified a combination of features within the known skeleton that indicate that Viavenator may actually be a transitional form,‭ ‬linking earlier abelisaurids of the Cenomanian and Turonian eras,‭ ‬with the later abelisaurids of the Campanian.‭
       Out of all the South American abelisaurids,‭ ‬Viavenator has been speculated to be more closely related to genera such as Carnotaurus,‭ ‬Abelisaurus,‭ ‬Aucasaurus,‭ ‬Pycnonemosaurus and Quilmesaurus.‭ ‬Like its relatives,‭ ‬Viavenator would have been a predator of other animals,‭ ‬and given the modest size of the holotype individual,‭ ‬a hunter of small to medium dinosaurs.
