Strange "Heads" In Opportunity Image on Mars

Was Mars inhabited by multiple species? Or should I say IS Mars inhabited by multiple species? The pictures provided by NASA provide us with more questions than answers.

What could we possibly be looking at?

Are we looking at 2 statue heads or artwork on the Martian surface?

This image truly stands out from many of the other Opportunity Rover images and shows anomalies that could be out of this world.

These anomalies looking like 2 heads were found by Thomas Mikey Jensen in 2014.

The image can be found on NASA's homepage or here at THIS LINK.

The picture is taken on the Martian day 3801 since the arrival of Opportunity on the surface of Mars.
