Re: Kickboxing Cassowary
So for those of you who are happy to throw out the idea of dromaeosaurs
"slashing" at their prey...why can a blunt-tipped claw like a cassowary
#2 pedal claw disembowel animals, and are the attacks described as
given that, what precisely would prevent the much more blade-like
dromaeosaur claws from being as (if not substantially more) effective?
Now, granted that on-line discussions may not adhere to the strictest
of medical standards, but people are claiming on the list (with
apparent seriousness) that keratin cannot maintain a sharp edge, when
every beak in existence that can cut through flesh derives that edge
I'm sure that a metal cast of a cassowary claw would fail to "slash"
pork rump, but that illustrates one serious flaw in the test design
(even ignoring the absence of the keratin sheath): dissembowling is
puncturing/ripping a relatively thin wall of muscle and connective
tissue to get at the internal viscera. Very much different from
attempting to slice through a dense belly of muscle. Dissembowelment
can occur from blunt objects with enough force behind them (e.g.
cassowary claws) and the sharp tips of tiger claws (which otherwise
lack a cutting edge) are quite proficient at it.
I grant you that it would be distasteful (although possibly popular on
tv) to try a similar experience on the side of the abdomen
recently dead deer, but that would be a far more plausible physical
