Has anyone done any studies showing a correlation between Triceratops (and
related sp.) frill size and the jaw gape of the (presumed) predators? Is there
an increase in size over time to cope with an increase in gape?
Sorry if this is a silly question, I'm an interested layman.
Also, I've noticed (in films) that predators of big animals tend to try and
grab the neck of the prey, either to break it or suffocate it. They try to
stay well out of the way of kicking feet. Could we hypothesise that T. rex is
perhaps designed for "head waggling" (I can't think of another term but it's
what dogs do for example) with the prey's neck, to try and dispatch it
quickly? It's got the weight to do it I would think.
Also, again, could the large "kicking" claw on (I can't remember the name but
it begins with a D) be used for climbing on the backs of larger prey to get at
the neck, rather than for disembowelling? Could one imagine predators which
specialise in one type of prey, using one successfull killing technique (until
the prey developed a counter-measure), rather than preying on all species?
Oh, and finally, for the moment, I don't understand the comment by Bakker on
"the hind legs overtaking the front legs". Hares and rabbits have vastly
different leg lengths, yet they seem to be reasonably successful at running
