Averostra was named by Gregory S. Paul in 2002 as an apomorphy-based clade defined as all theropods with a promaxillary fenestra. It was later re-defined by Ezcurra and Cuny in 2007 at a node-based clade containing Ceratosaurus nasicornis, Allosaurus fragilis, their common ancestor and all its descendants.
