        What have they found T. rex teeth in (besides other T. rexes)? 
How about other predators? 
        other stuff:
I had envisioned ankylosaurs hitting each other in the sides, rather than 
tails, with their clubs, but I'm forced to admit that looking at it again 
makes it look- well, backwards. I can't imagine Ankylosaurs NOT using a 
club on a predator, it's just that I figured maybe that was a secondary 
use. As for what would eat an ankylosaur- I'd guess they didn't have a 
lot to worry about, but Tyrannosaurs are big animals, capable of biting 
through the head of a Triceratops femur. I might still be wary as an 
ankylosaur.And good point about keeping the tail between 
the head and the predator. 
        I was looking at yet another squirrel, wondering about his 
perspective on the world, and wondering if his skull would show anything 
about that- would animals that live a great deal of the time in trees or 
up in the air show differences in their orbits? Some birds have downward 
directed eyes for watching fish, I believe. I was wondering whether this 
would be of any use in examining suspected arboreal animals. I'd guess 
that Archaeopteryx would probably be too flattened to show any 
downward direction of the orbits (if such features exist) 
but that Drinker, which Bakker should have the skull of, and which would 
be preserved in full 3-d, might show such features if indeed it were 
arboreal and there are differences in the skull design.
