Recently, the large unenlagiine Austroraptor cabazai
has given a peculiar focus on some adaptations of the jaws normally found in other, unrelated theropods.
With short, numerous teeth lacking serrations and with fine striations on the crowns, a long and low maxilla with short lateral exposure of the antorbital fossa, and a cranially curving preorbital bar, this skull reminded many of spinosaurids when it was first unveiled in 2006's SVP in Denver. However, it clearly is related to Buitreraptor
, only much, much larger -- [link]
