Ancient statue head discovered on Mars

On October 2014, famous ufologist Scott C. Waring has found on a photo published on NASA website a possible ancient statue head on Mars. What is it? An optical illusion or a alien’s skull?

Waring explains:

This interesting head was found on Mars this week and shows us an elongated skull, much like we have seen with some ancient skulls on Earth. We have seen such skulls in ancient Egypt and murals. From its curvature, this face looks reptilian. I have found other reptilian heads on Mars which only reenforces the the proof that the species did exist on this planet, but its only one of many species which inhabited Mars. This giant head would be about 3-5 meters across. It looks like its the head of an ancient statue. The statue may be buried from the neck down. SCW
