Alien or something else?
Normally I would not give something like this much thought, however, there was something very similar to this on Destination Truth. They investigated a cave which the locals claimed had aliens living in it. They didn’t expect to find anything, instead they found a tiny grave. They pulled out the little corpse and something looking like this was wrapped in a cloth. After they found the body, they experienced a lot of strange phenomenon. They were also somewhere in South America.
