No it's pretty real. People don't just make these things in the middle of no where at a quality that well done that no one will potentially see. Something ripped the top half off and drug it away, the other half had been licked clean. Australia has some crazy carnivorous animals out there.
Shouldn't there be more blood? Or, if the remains are old, shouldn't the fur near the feet be decomposed more?
Can't get caught by any drop bears and the like.
