Re: Deinocheirus 2nd try
_Deinocheirus_ possessed the most formidable set of forelimbs on any creature
hitherto discovered. It's arms and claws are unlike those found in its relative,
_Therizinosaurus_. Apparently the proportions of key bones in the forelimbs are
the same. I belive the forearms are proportionately shorter than those in
_Therizinosaurus_. The claws are also very different being more curved and
relative to length. Admittedly, they do appear like predatory devices from a
glance, but looks are often deceiving in the world of paleontology.
In any case, it's difficult to determine with certainty in the absence of
material (most notably, the skull). I too, have often times speculated on the
_Deinocheirus_ and its general appearance. Although in the past
proposed _Deinocheirus_ as a ~25' tall super-predator in a world where
as _Tyrannosaurus_ were primarily scavengers, this hypothesis has since been
Current speculation on _Deinocheirus'_ feeding habits runs the gamut from being
herbivorous, carnivorous, or even possibly omnivorous. All this speculation is a
result of not knowing what the skull was like.
If _Deinocheirus_ was indeed carnivorous, it would have gone against the
trend amongst giant predatory dinosaurs that rely on dentition for their main
weaponry. The forelimbs of theropods have seen a gradual decline in size
their evolution. What evolutionary pressure would have been exerted on
to evolve huge arms and claws for killing, would largely have depended on the
prey it hunted. If indeed more complete _Deinocheirus_ remains are found one
and it proves to have been a predator after all, I would love to know what kind
animal fell victim to those claws...
