Oppinions and questions
Well after the Falcarius find (and even before that) I came to think that
though therizinosaurs specially basal ones might have used the big claws to
bring branches to mouth's reach it seems too farfetched to be a very common
behaviour for one simple reason: the necks reach further than the claws. In
the "Chased by Dinosaurs" WWD special on the Gobi Desert I found it
particularly ridiculous that a Therizinosaurus individual was "clipping" a
bush lower than the creature itself was, when it could have as easily
hunkered down much like a goose and foraged on the branches now at a much
more convenient height. Not mentioning that the claws could do their
propurted job better in this position.
I'm with another member of this list in the assertion that the claws were
used mainly for defense. If they were use for aggression in the forebearers
of "scythe-lizards", defense can coopt the same structures rather easily.
In the same manner if the hands were also display devices in these ancestors
I would think that therizinosaurs would flash the claws to resolve social
disputes. Perhaps one can even paralell Therizinosaurus big claws to the
tusks of proboscideans though one should take care in making such
Now for a few questions:
Suscited by a conversation I had at Dinoforum.net I'd like to ask what
became of the ankylosaur and hypsilophodont found at James Ross Island in
the 80's. Were they studied or are they still resting in some museum shelf?
A strange mention of a parallelism at the same forum, between Falcarius and
Deinocheirus, makes me wonder: Is there any way the later can be a giant
form of basal therizinosauroid? Or is it still largely considered as an
