It just isn't any fun if everyone says there's no doubt.
One could argue that the arm caught in the trap is consistent with the creature reaching for something on the trap and then recoiling when it sprung.
The missing hand could also be consistent with the limb losing circulation of whatever type fluid the creature ciruculates and either falling off and
being eaten, or just lost.
I would think that an E.T. would have the decency to wear some clothes, but what do I know?
The radius and ulna are very interesting...common in primates...not sure about in E.T. or chupacabras.
The following skeleton looks very similar to what we are seeing, IMO...
Goeldi's Monkey
It might be interesting to note that The Goeldi's Monkeys are endangered, so it might make a person feel better to skin one that got caught in a trap
and feign ignorance rather than admit to one dying a painfully horrible death at their hands.
The writeup on the OPs external link refers to an abnormal number of teeth...the Goeldi's has quite a few more than a standard monkey.
The lack of toes is very suspect as is the apparently broken tail...if you look at the left foot, there is obviously a very straight edge where toes
SHOULD be....
Ok....I guess I can stop there...looks like a poor skinned monkey.
The bastards.
