I had an idea a long time ago for a purpose for
Tyranosaur arms. Its completely unprovable of course but I wonder
what others would think of it. The arms of Tyranosaurs are small but
very powerful. Perhaps like the antlers of deer they were used to judge
the strength of the opposing Tyranosaur in a non violent way. They would
stand side by side facing each other, lock their two fingered hooks, and press
against each other till it was apparent who was stronger.
Did the anatomy of their
wrists permit this?
