Hey all, definitely worth the trip. VERY fascinating, but it raises a 
question that I find thought provoking.  In the words of Sam Welles 
Dilophosaurus had a manus with  4 digits, one vestigal (smallest) and 
one that apparantly was opposing.  

1st Question:  I am assuming they speculate, or know, it was opposing 
by how it attaches the the skeleton's wrist?

2nd Question:  If it had an opposable (digit) (which of course is
often referred to as one reason primates were so successful 
evolutionarily) was Dilophosaurus a tool user?
