Extinct genus of dinosaurs
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.
Filippi classified "Viavenator" to a new clade known as the Furileusauria, which includes "Viavenator" as well as "Carnotaurus". This would have meant "Viavenator" was closer to "Carnotaurus" than "Majungasaurus". It would have been in length.
Palaeobiology.
"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.
