RE: Claw function in Deinonychus
As Bill Oddie, a well known bird lover and lesser known comedian was hosting
the programme, the turkeys were deceased.
Now if other well known comedians had been hosting the program (think Monty
Python) it may have been different.

Perhaps not *all* troodontids. In _Borogovia_ this claw is straight, not
sickle-shaped, and it's hard to imagine how useful it could have been as a
predatory tool. In _Tochisaurus_, the second metatarsal is reduced and very
slender, so the second toe may have lacked a "killer-claw".
AFAIK, the idea that the deinonychosaurian sickle-claw was used as an
eviscerating device goes back to John Ostrom and his studies on
_Deinonychus_. (Sorry if this has been mentioned before - I came in late to
Finally, there is a contrarian view that the sickle-claw originally evolved
as a tree-climbing aid, and was later exapted into a predatory instrument.

Sounds like a fun thing to do at Thanksgiving - except if you happen to be
the poor turkey standing around waiting to be thagomized by a tail-club.
Just dragging the bird to the chopping block is probably more humane, and
much less messy.
