Who needs to pierce hide when you've got a narrow head and long neck, and 
nature has provided 
a ready-made access chute for reaching the intestines? Some of the smaller 
vulture species that 
lack the strength to pierce hide opt for the sphincter option.

I've always wondered whether alvarezsaur forelimbs were attrophied from general 
lack of utility 
(as in Carnotaurus), with the only function left being that of intraspecific 
kangaroo-style wrestling
