Four teenagers in Panama claim they encountered a creature that was photographed, dead on a rock.
It appears to have an animal-like head, but a strange body with skinny, human like arms. Some say it's an alien while others say it's an animal that's never been seen before.
The teens said, the creature was alive when they found it and it started coming after them, so they threw rocks and sticks at it, killing it.
Zoologists in Panama said they're not sure what it is, but it appears to be a dead fetus of some kind.
UPDATE: Darren Naish of ScienceBlogs.com says the creature is "very obviously" a sloth, though he has a difficult time explaining its hairless torso and head.
