I used a nifty program called Photo Zoom Pro. Photo Zoom allows you to zoom into pictures with virtually no loss in image quality. On the final image to the bottom-left, I used a edge detection filter to enhance the outlines of this object. Take note about some of it's features, the two prong-like things in front of the "nose" area. The raised arch going from the front to the rear of the object. Also look closely at the evenly spaced indentations in the frontal raised arch. The two "eye" sockets on both sides appear to be evenly spaced and positoned across from each other.

Either I have a vivid imagination, or this thing looks like a skull ......... on Mars.

Enjoy !
