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?
