Avetheropoda, or "bird theropods", is a clade that includes carnosaurians and coelurosaurs to the exclusion of other dinosaurs.

Definition

Avetheropoda was named by Gregory S. Paul in 1988,[1] and was first defined as a clade by Currie and Padian in 1997, to include Allosaurus, modern birds, and other animals descended from their most recent ancestor. In 1999, Paul Sereno named another group, Neotetanurae, for the clade containing Allosauroidea and Coelurosauria, and excluding other tetanurans such as megalosauroids,[2] but this definition was published slightly later.

Classification

The cladogram presented below follows a phylogenetic analysis published by Zanno and Makovicky in 2013.[3]

Orionides

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. Their phylogenetic analysis has found Megalosauroidea to be a basal grade of carnosaurs in respect to Allosauroidea.[4]
