Unquillosaurus | 1979 | Los Blanquitos Formation (Late Cretaceous, Campanian) | Argentina | Has been suggested to be a dromaeosaurid[51] or a carcharodontosaurid[52] | |
Velocisaurus | 1991 | Bajo de la Carpa Formation (Late Cretaceous, Santonian) | Argentina | Unusually, its third metatarsal is the thickest | |
Vespersaurus | 2019 | (Late Cretaceous) | Brazil | Possessed raised claws on its second and fourth toes, making it functionally monodactyl, a possible adaptation to its desert habitat | |
Viavenator | 2016 | Bajo de la Carpa Formation (Late Cretaceous, Santonian) | Argentina | May have relied on quick movements of its head and gaze stabilization when hunting | |
Volkheimeria | 1979 | Cañadón Asfalto Formation (Early Jurassic, Toarcian) | Argentina | Its neural spines were very low and flat | |
Willinakaqe | 2010 | Allen Formation (Late Cretaceous, Campanian to Maastrichtian) | Argentina | As originally described, it represented a chimera of two different taxa, one of which was later named Bonapartesaurus[12] | |
Xenotarsosaurus | 1986 | Bajo Barreal Formation (Late Cretaceous, Cenomanian to Turonian) | Argentina | Had an unusually-shaped astragalus and calcaneum | |
Yamanasaurus | 2019 | (Late Cretaceous, Maastrichtian) | Ecuador | The northernmost saltasaurine known to date[42] | |
Ypupiara | 2021 | (Late Cretaceous, Maastrichtian) | Brazil | May have been a piscivore due to the shape of its teeth[53] | |
Zapalasaurus | 2006 | La Amarga Formation (Early Cretaceous, Hauterivian to Aptian) | Argentina | Known from an incomplete skeleton, including several caudal vertebrae | |
Zupaysaurus | 2003 | Los Colorados Formation (Late Triassic, Norian) | Argentina | Although commonly depicted with head crests, they may in fact be misplaced lacrimal bones[54] |
Dubious, uncertain, and invalid genera[]
- Angaturama limai: Only known from the tip of the snout. It may belong to the contemporary Irritator, but it could also represent its own taxon.
- "Bayosaurus pubica": An abelisaurid known from partial postcranial remains.
- Gnathovorax cabreirai: Known from a well-preserved, almost complete specimen. It may not be a dinosaur.
- Herrerasaurus ischigualastensis: The type genus of a family of basal predators called herrerasaurids. They may represent early dinosaurs, possibly saurischians, but they could also be just outside Dinosauria.
- Oxalaia quilombensis: Potentially a junior synonym of Spinosaurus.
- Sanjuansaurus gordilloi: A herrerasaurid that, like the other members of its group, could be non-dinosaurian.
- Taurovenator violantei: Only known from a single postorbital, it may be a junior synonym of Mapusaurus.
- "Ubirajara jubatus": Known from a single specimen that preserves impressions of feathers, including display feathers on its sides. Its description was retracted before it could be published due to allegations that the specimen was illegally exported from Brazil.
Timeline[]
This is a timeline of selected dinosaurs from the list above. Time is measured in Ma, megaannum, along the x-axis. Carnivores are shown in red, herbivores in green and omnivores in blue.
