Daemonosaurus differs from Coelophysis bauri in the presence of the extreme protruding teeth, a significantly larger prefrontal, and in the dorsoventrally deep premaxilla. A phylogenetic analysis of basal dinosaurs recovers Daemonosaurus outside of Neotheropoda as the sister taxon to Tawa hallae + Neotheropoda.
One possibility I find interesting is that we now have four theropods known from the Upper Triassic in the Ghost Ranch area, Tawa, a coelophysoid, and Chindesaurus from the Hayden Quarry (Petrified Forest Member) and Coelophysis and Daemonosaurus from the Coelophysis Quarry (siltstone member). Currently Chindesaurus lacks a preserved cranium, whereas Daemonosaurus is known almost exclusively from the skull. Thus, it is possible that they could represent the same or a similar taxon. Only the discovery of more complete material of either taxon can test this idea.
