Description
Morphotype VI
A few isolated theropod teeth could be described as resembling those of the lateral dentition of an allosauroid. They are, once again, relatively similar to abelisaurid lateral teeth of morphotype I but differ from the latter in being asymmetrical in basal/apical view, with the distal carina being slightly deflected labially, while the mesial carina is straight to weakly twisted lingually. The crown is also slightly thicker (but also in abelisaurids), and the mesial and distal denticles are symmetrically convex. The distal margin can show a convex apical profile in lateral view, as is typical of carcharodontosaurids (in LPPV-PV 1102).
Identification: We refer these allosauroid-like teeth tentatively to abelisaurids, whose lateral dentition would be convergent to that of carcharodontosaurids.
