Archaeornithoides is a Théropode discovered in 1965 in Mongolia in the formation of Djadokhta (Bayn Dzak). This dinosaur of the Cretaceous was described by Elzanowski and Al in 1992. It is phylogenetically near to the bird. The incomplete cranium of Archaeornithoides presents characters present at the Spinosauroidea, the Tyrannosauroidea and the Troodontidae; moreover some make a youthful Saurornithoides of it. Holtz et al., 2004, classify it in the great group of the Coelurosauria.
