Guaibasaurus was a basal Saurischier , which possibly belonged to the Theropods , but is sometimes also to the Sauropodomorphs or Herrerasauriden. Like Herrerasaurus and other early dinosaurs, it had three fully developed and two receding fingers.
It reached a height of 1.2 meters, a length of 3 meters and a weight of 100 kg.
Bonaparte , Ferigolo and Ribeiro discovered him in 1999 in Brazil ( Caturrita Formation ).
Bonaparte found in 2007 that Saturnalia and Guaibasaurus are very closely related and grouped them together as Guaibasauridae . They were probably ancestors of the Theropoda .
