Pandoravenator fernandezorum was named by Rauhut and Pol (2017) [Small to medium-sized theropod dinosaur that can be diagnosed by an astragalus with anterior and distal lateral tubercles adjacent to the contact with the calcaneum, an anteriorly facing part of the astragalar body that is offset from the distal part by a transverse groove anteriorly, an ascending process of the astragalus that is laminar, but very low (about one third of the height of the astragalar body), triangular in outline in anterior view, and inclined laterally, and the shaft, but not proximal end, of metatarsal III being strongly constricted between the shafts of metatarsals II and IV. A further potential apomorphy, based on the referred material, is the postzygapophyses of posterior caudal vertebrae being elongate to overhang approximately half of the length of the following vertebral centrum.]. Its type specimen is MPEF PV 1773, a partial skeleton (MPEF PV 1773-3, distal end of right femur and proximal end of right tibia; 1773-6, proximal end of right fibula; 1773-5a, b, fragment of the proximal shaft of t), and it is a 3D body fossil. Its type locality is Caja de Pandora, which is in an Oxfordian/Kimmeridgian lacustrine siltstone/sandstone in the Cañadón Calcáreo Formation of Argentina. It is the type species of Pandoravenator.
