A bizarre artifact has been found on the red planet by the Mars Curiosity Rover.
After studying the official NASA image I strongly believe that this artifact is possibly the carved top or lid of an ancient tomb. Possibly holding the remains of a Martian Knight or King.
According to Enkispeaks artwork on Mars found thus far consists almost entirely of statues of human and animal heads, intaglios carved casually on rocks featuring human and alien faces, and vast etchings carved on the ground conveying human and animal themes.
A photograph of the Martian surface that was taken by NASA’s Mars Exploration Rover Spirit during November 6-9, 2007 and beamed back to Earth” shows earlier Martian settlement.
The built structures found in the photograph include an image carved on the slab that resembles an Egyptian pharaoh and several large stone sarcophagi, including the ossuary of a king in the Egyptian style laid on a cliff top.
The video below shows the carved top or lid of an ancient tomb.
