Dear Mike and List,
It seems to me that the general opinion of duckbills, is that they
the equivalent of domesticated farm animals. When a predator got through
fence, they just stood there as one by one they where decimated.
TMK, All of the duckbills grew as large, or in some cases, much
than thier predators. If you want to see something really cool, visit The
Dinosaur Museum in Blanding, Utah. They have a hadrosaur mummy with thick
dorsal and caudal spikes that measure over eight inches tall. Add to that a
powerful well muscled tail, dense scales, and you have a dinosaur with some
fire power. I can just imagine a T-Rex running into a 15 meter lambeosaur,
jaws agape, only to have the crap slapped out of it by the duckbill's
lashing multi tonne tail.
This reminds me of K. Carpenter's 1988 tail bite paper, but the idea isn't
credible. Hadrosaur tails were stiffened; if they were incapable of the
movement required for swimming, defensive use also seems unlikely. Nor did
the hadrosaurs evolve caudal weapons which would have enhanced such a
I guess my point is that these animals could probably take care of
By running away, but not hadrosaurs could escape a new predator with
consummate senses and speed.
I personally believe that like in all modern carnivores,
tyrannosaurs mostly preyed on the young, sick and the old, ...like lawyers.
