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]

	Spinosauridae

	Megalosauridae

Avetheropoda

	Neovenatoridae

	Carcharodontosauridae

In 2019, Rauhut and Pol described Asfaltovenator vialidadi, a basal allosauroid displaying a mosaic of primitive and derived features seen within Tetanurae. Their phylogenetic analysis found traditional Megalosauroidea to represent a basal grade of carnosaurs, paraphyletic with respect to Allosauroidea.[4]

Orionides

Avetheropoda

Asfaltovenator vialidadi

	Neovenatoridae

	Carcharodontosauridae

gollark: This isn't for sandboxing, though, just undoing what CraftOS does.

gollark: PotatOS's potatoscheduler uses a TLCO thing to escape this and run its own main loop.
