To respond to one of my own messages, I'm not sure if the preserved 
portion of the _Irritator_ skull shows clearly if the rostrum was 
spatulate - constricted at the premaxilla-maxilla suture.  But I 
believe _Angaturama_ does show this feature.  Regarding 
_Irritator_ and _Angaturama_ as the same theropod does make this 
theropod a lot more spinosaurid-like.
