Viavenator (meaning "road hunter") is a genus of carnivorous abelisaurid theropod dinosaur discovered in Argentina's Bajo de la Carpa Formation. It coexisted with the megaraptoran Tratayenia rosalesi.
Classification[edit]
Filippi classified Viavenator to a new clade known as the Furileusauria,[1] which includes Viavenator as well as Carnotaurus. This would have meant Viavenator was closer to Carnotaurus than Majungasaurus. It would have been 5.6 metres (18 ft) in length.[2]
Palaeobiology[edit]
Viavenator possessed a similar brain morphology to Aucasaurus, another South American abelisaurid and had a similar inner ear. Compared to the Madagascan abelisaurid Majungasaurus, Viavenator was more reliant more on quick movements of the head and sophisticated gaze stabilization mechanisms; however, both genera had a similar range of hearing according to the examinations and subsequent CT scans of the cranium.[3]
