Diagnosis
ReferenceDiagnosis
H.-D. Sues et al. 2011"Distinguished by the following unique combination of characters: skull proportionately deep and narrow, with short antorbital region; premaxillary and anterior maxillary teeth much enlarged relative to more posterior maxillary teeth; prefrontal large and occupies about 50 per cent of the dorsal margin of the orbit; ventral process of lacrimal with slender posterior projection extending along anterodorsal margin of jugal; dorsoventrally deep jugal with prominent lateral ridge; postorbital with anterolateral overhang over
orbit; first two dentary teeth large and procumbent; alveolar margin of dentary downturned at symphysis; and third cervical vertebra with deep, rimmed, ovoid pleurocoel on the anterolateral surfaces of both centrum and neural arch. Possible autapomorphies of Daemonosaurus include long posterior process of premaxilla that almost contacts anterior process of lacrimal and antorbital fenestra nearly the same size as external naris. Daemonosaurus differs from Herrerasaurus ischigualastensis in having a much anteroposteriorly shorter antorbital fenestra, a posteroventral process of lacrimal that extends along the anterodorsal margin of the jugal, and much enlarged premaxillary teeth. Daemonosaur us differs from Eodromaeus murphi in the absence of a distinct ridge on the lateral side of the maxilla, the proportionally much smaller antorbital fossa, presence of much enlarged premaxillary teeth, presence of a posteroventral process of the lacrimal that extends along the anterodorsal margin of the jugal, and greater dorsoventral expansion of the jugal. Daemonosaurus differs from Eoraptor lunensis in the presence of much enlarged premaxillary and anterior maxillary teeth and a much more restricted antorbital fossa on the maxilla. Daemonosaurus differs from T. hallae and the neotheropod C. bauri especially in the presence of a dorsoventrally deep premaxilla, a slight subnarial gap and a proportionally larger prefrontal. Daemonosaurus differs from Chindesaurus bryansmalli in the presence of an ovoid deep depression on the anterior portion of the centra of postaxial cervical vertebrae (postaxial cervical vertebrae are the only bones currently known for both taxa)."
