the second metatarsal is both mediolaterally compressed and features a prominent dorsolateral ridge. These traits imply it is a valid taxon and different from Neovenator and Eotyrannus. Olshevsky assigned Valdoraptor to the Allosauridae but Naish in 2007 stated that no more precise determination was possible than the more general Tetanurae. A 2014 re-evaluation found that Valdoraptor was likely one of the oldest known ornithomimosaurs, and a possible junior synonym of Thecocoelurus.
