Re: Humor: the Uses of Sickle Claws
Actually, what I'm objecting to is the depiction or Deinonychus et al as
using JUST those toes as their only attack weapons while the others dangle
uselessly. And again, they need to be able to do far more than just
support the animal's weight. An object flying through the air strikes with
much more force than just its normal weight- and then it has to hang on to
its prey which is probably not going to just stand still and let itself be
But of course I'm sure that Dromaeosaurids were capable, savage predators
and could do lots of damage with their toes and claws and teeth.
Also I have a problem with artwork that shows digit two retracted as far
back as it could possibly go- NO MATTER WHAT POSITION THE LEG AND FOOT ARE
IN! To me that is indefensible nonsense and it started with Ostrom (and
even more powerfully, Bakker's famous drawing of the running Deinonychus-
which looks like it would disembowel itself and shred its own elbows
running that way!) Sorry if I beat this into the ground, folks. I know
many of you are sick of it.
