To be honest, this is, in fact, a really interesting formation.

Others are calling it an arch , which it is , but this interesting formation has been found by Curiosity rover at the base of Mount Sharp , personally I see a Martian crocodile attacking a Martian sea snake.
“I continue to be dazzled by the textures we’re seeing, especially the prevalence of centimeter sized bumps and lumps poking out of the bedrock,” planetary geologist Abigail Fraeman of NASA’s Jet Propulsion Laboratory wrote in a blog post about the feature.
The arch (lizard) is about 6.5 inches tall.
Man, I can hardly wait until we get people up there and can really know exactly what we are looking at!
Is this a Fulgurite?

Fulgurites (from the Latin fulgur, meaning “lightning”), commonly known as “fossilized lightning”, are natural tubes, clumps, or masses of sintered, vitrified, and/or fused soil, sand, rock, organic debris and other sediments that sometimes form when lightning discharges into ground. Fulgurites are classified as a variety of the mineraloid lechatelierite. When ordinary negative polarity cloud-ground lightning discharges into a grounding substrate, greater than 100 million volts (100 MV) of potential difference may be bridged. Such current may propagate into silica-rich quartzose sand, mixed soil, clay, or other sediments, rapidly vaporizing and melting resistant materials within such a common dissipation regime. This results in the formation of generally hollow and/or vesicular, branching assemblages of glassy tubes, crusts, and clumped masses. Fulgurites have no fixed composition because their chemical composition is determined by the physical and chemical properties of whatever material is being struck by lightning….

Wow thats so cool, does Mars have lightning? I assume so, but have no idea.

Present day Mars does have lightning, it is thought to be fairly rare, and generated in large dust storms, it’s believed to be much weaker than we get here on Earth. Lightning on Mars was detected by a radio telescope several years ago during a major dust storm link
3.5 billion years ago when these rocks were deposited as lakebed sediments, Mars was a much wetter place, so we could expect more lightning back in those days before the climate changed.
