 In 1999, Paul Sereno named another group, Neotetanurae, for the clade containing Allosauroidea and Coelurosauria, and excluding other tetanurans such as megalosauroids, but this definition was published slightly later.The cladogram presented below follows a phylogenetic analysis published by Zanno and Makovicky in 2013.In 2019 saw the description and publication of "Asfaltovenator vialidadi", a basal allosauroid that curiously has characteristics displaying primitive and derived features seen in Tetanurae.
