RE: Rookie Questions
There is (I think) only one species of Protoceratops. I'm sure someone
will correct this, if I'm wrong.
As far as Hadrosaur defenses, I agree about kicking - the biomechanics
seem wrong for that. I'm not sure about Hadrosaurs biting as a defense. I
think pretty much any animal WILL in a pinch. I wonder about the
effectiveness of Hadrosaur tails as a defense. It seems to me that I have
read that as much as 50% of the weight of some Hadrosaurs might have been in
the tail. That would be a pretty formidable bludgeon. And with the taller
Hadrosaurs, the tail would have been pretty high off the ground. The person
who would know (if anyone would) might be Dr. Horner, who is a Hadrosaur
expert. He wrote a book some years back, called (I believe) "Digging
Dinosaurs", in which there was a good bit of information about Hadrosaurs.
I believe it's still in print.

Are you asking specificaly about Protoceratops or Protoceratopsidae?

Probably for the same reson there aren't very many words that start

Kicking and clawing is out. Why you may ask? Because of the tail,
in the way. I did some drawings for Darren Tanke nearly 10 years ago
(has it actually been that long?) about how hadrosaurs could have
broken ribs. They couldn't kick backwards the tail is in the way.
legs dont' move sideways, so thats out, and only way for a forward
to work is if the kicking animal held onto the kicked animal with
front legs. The more formable weopon IMHO is the mouth.
Glad to hear your not discourged by the list. If you don't find the
answer to you questions, write them down, and in the furture if you
to prosue paleontology, you can take up the question and answer it
all of us.I've several written questions that I hope to prosue.

Only Tyrannosaurus rex has been done (as answered by a list member
Megalosaurus is being done). So in the furture you could take it up.
