Guaibasaurus (meaning "Guaiba lizard") was a basal Saurischian dinosaur genus which lived during the late Triassic period. Its fossils were found in the geopark of Paleorrota, Rio Grande do Sul, Brazil (red beds of the Caturrita Formation, dated to about 225 million years ago). Like Herrerasaurus, this dinosaur had three full fingers and two vestigial ones on each hand. The type species, G. candelariai, was described by Jose Bonaparte and J. Ferigolo in 1999.
