Actually, it has even more to do with the fact that the specimens are so
fragmentary and rare. More and more complete specimens of caenagnathids
would really go a LONG way in clearing htings up.

NEVER assume that. However, you can assume that it is the best you can do
for now. (It's the same sort of thing as planetary astronomy: don't assume
stuff is completely correct, because the next probe to the planet in
question could change your information. Same thing here: the next dig could
reveal a lot more).
