Let's assume that the
_Carnotaurus sastrei_ has had his horns nothing more than an exhibitional add to
its head. And that his arms have had some purpose. What could it be, if they're
so small, theorically weak, and did not reach much longer thatn a few inches
from it's body? And, if the "use or non-use" (sounds like Lamarck...) of the
arms for anything makes them bigger and stronger, or smaller and weak, why did ,
assuming the following theories, the _Tyrannosaurus rex_ and _Spinosaurus
aegypticus_ have had so big "arm differences" if both used only their mouth to
eat: _T. rex_ because of his small arms, and _S. aegypticus_ because he caches
fishes with his mouth (or feed on dinosaur corpses, like _T rex_ may did
too)?
Somehow, I think that
_Carnotaurus sastrei_ did not needed that much of his arms than his legs, but
that means he could be, in a possible future, evolved into a
dinosaur which arms had disappeared, according to some affirmations.
Am I wrong?
Thanks.
