[3] The skull roof exhibits as a unique diagnostic character a midline foramen, possibly housing the pineal gland, situated on the posterior surface of a slight dome formed by frontal bones as moderately thick as in Aucasaurus, thus less so than for Rajasaurus, though more than those of Rugops.

[1] The postorbital is intermediate between the plesiomorphic T-shaped condition of Eoabelisaurus and the derived inverted L-shaped one of Carnotaurus due to the unique feature of having a sheet of bone linking its ventral and posterior processes.

[1] The ear region closely resembles that of Majungasaurus, though differing most substantially on a laterally directed basipterygoid process, with the shorter crista prootica and the smaller extent of a groove anterior to the 2nd and 3rd cranial nerve foramina being minor deviances from Majungasaurinae's type.

[7] Thierry Tortosa and colleagues conducted a phylogenetic analysis, which is summarized in the cladogram below and is based, in part, on previously published works including both the newly discovered fossil remains and other described but unnamed French abelisaurs.

[1] As the inferred character distributions obtained through the phylogenetic analysis make it unlikely that these lineages are more closely related to each other than to other abelisaurids, this suggests a more complicated series of events regarding their biogeography with vicariance applicable to the older one and oceanic dispersal being likelier for the more recent one.

[1][8] The fossil remains of A. escotae were found near Pourrières, Var department, Provence-Alpes-Côte d'Azur region, during preventive paleontological and archaeological prospection activities before construction took place on the stretch of the A8 motorway between Châteauneuf-le-Rouge and Saint Maximin.

[1] The holotype of Arcovenator escotae, housed at the Muséum d’Histoire Naturelle d’Aix-en-Provence, was found closely associated in a single stratum of fluvial sandstone and is made up of specimens MHNA-PV-2011.12.1, a braincase in articulation with a right postorbital, MHNA-PV-2011.12.2, a left squamosal, MHNA.PV.2011.12.15, a tooth, MHNA.PV.2011.12.5, MHNA.PV.2011.12.5, an anterior caudal vertebra, MHNA.PV.2011.12.3, a right tibia, and MHNA.PV.2011.12.4, a right fibula.

[9] The compressional subsidence basin of Aix-en-Provence was a low-relief endorheic affair located at a paleolatitude of 35°N, and had its borders to north and south in the form of limestone highlands, respectively the Sainte Victoire and Etoile massifs, and to the east as the Maure Mountains.

[13] The fossil remains were found in one of the formation's various levels of fluvial sandstone,[1] characteristic of a river's mouth or when it overflows its banks,[13] along with hybodonts, the turtles Foxemys and Solemys, the crocodylomorphs Musturzabalsuchus and Ischyrochampsa, azhdarchid pterosaurs, titanosaurian sauropods, the ornithopod Rhabdodon and nodosaurids.
