A group of alien hunters who call themselves 'Paranormal Crucible' claim to have identified the skull of a giant alien just lying about on the surface of the planet Mars.
The strange object was spotted in images beamed back to Earth by Nasa's Curiosity Rover, which has been on Mars since 2012.
In a video posted on YouTube, the self-styled paranormal investigator said the skull was 'obviously alien in nature' and appeared to resemble the remains of the mythical Sasquatch, also known as Big Foot.
A writing under the video said, "Strange artifact found by the rover, appears to resemble a large skull, obviously alien in nature, could it be the remains of a Sasquatch or a bizarre Martian creature?"
This is not the first reported sighting of a suspicious object spotted by alien hunters since the Curiosity Rover landed on the red planet.
Other bizarre claims include capturing images of a shark on the planet's surface, a crucifix, a mouse, various faces (including that of God's), and even an Egyptian sarcophagus.
