Aublysodon molnari Paul 1988 :

The type species of Aublysodon mirandus is a set of isolated premaxillary teeth from the Tudith River Formation of north-central Montana. Currie (1987) referred primitive triangular tyrannosaurid frontals from Dinosaur Park Formation to cf. Aublysodon . A second species of Aublysodon , A. molnari , was proposed for material from the Hell Creek Formation of eastern Montana, formally known under the label "the Jordan theropod" ( Molnar 1978). Currie (1987), Paul (1988) and Molnar and Carpenter (1989) referred this material to Aublysodon . Olshevsky et al. (1995b) went further to use this specimen as the type of a new genus, " Stygivenator ," distinguishing it from A. mirandus in having premaxillary teeth which are narrower in lateral view: whether this is taxonomically significant or due to allometry or even different tooth positions in the premaxilla has yet to be determined.
