Paranormal Crucible makes a hypothesis that this could be an ancient tree stump on Mars. Its a good assumption since NASA themselves said Mars was Earth-like when a solar explosion hit the planet, striping the atmosphere and oceans from its surface.

Paranormal Crucible states: 
Intriguing object found by the curiosity rover, this time a possible tree stump. This object definitely looks out of place and in my opinion could be the petrified remnants of a Martian tree. Object is around 3 feet in height, and with numerous discoveries of plant and animal life on mars, it would be logical to assume, that a variety of tree either existed, or still exists on this enigmatic planet.
