Erythrovenator

Erythrovenator is a genus of basal theropod dinosaurs from the Late Triassic of Rio Grande so Sul, Brazil. The genus contains a single species, Erythrovenator jacuiensis.

== Discovery == The holotype and only known specimen of Erythrovenator, CAPPA/UFSM 0157, is an isolated proximal portion of the left femur. This fossil was found in red mudstone of the Niemeyer Site, near Agudo in Rio Grande Sul. The site is tentatively considered to be early Norian (or possible late Carnian) in age and belongs the Candelária Sequence of the Santa Maria Supersequence. No other dinosauromorphs are known from this site, which is dominated by the traversodontid cynodont Siriusgnathus. The site probably corresponds to the Riograndia Assemblage Zone based on the presence of Siriusgnathus.
