Mystery Surrounds Find of Strange Creature with Alien Appearance

my problem is the eyes look like a bad sculpting job. not round, sudden slope at top of eyeball. looks bad. looks like there are no functioning parts. I've done some sculpting and have made alien heads much better than that lol.

Perhaps the arm fused during the crash?

OK, there is an update on the site that says that they have shown the pictures to various experts and 3 have said that it could be the deformed fetus of a Greater Rhea bird. They have added a picture of a Rhea fetus as example on the same link.

The Greater Rhea is usually found in the extreme south of Chile (Punta Arenas) not so far north, but there are some Rhea Farms where they are grown for the meat, so it could be possible.
