Fused nasal bones - this would only hold for mature adults?
Nope. Even juveniles like the Stygivenator holotype (actually juvenile
Tyrannosaurus) had fused nasals. Not AS fused, but still...
Which sorta implies to me that fusion perhaps started earlier on (my
exposure to sutures etc fusing is that it's more reflective of a mature
adult that for young).
