curiosity rover discovers "thigh bone" on mars

[ArMaP]

What I have here came from the area in the upper left where the rover felt the need to go back and forth.  I thought the cameras could do 360 swivel?  Why did the rover do that?  (ArMaP, I'm sure You will enlighten. [smile])

The mast that has the main cameras can do 360º rotations, and the MAHLI camera is on a moving arm (that's how Curiosity makes "selfies"), so I don't know why they, sometimes, move the rover around. Some time from now, when the data for this Sol is to the MSL Curiosity Analyst's Notebook we will be able to read the activity plan for that day and (maybe) understand why they did all those moves.

What I have delineated with the black lines and circle is the path of the treads that suggests that there should be a treadmark in that soft-looking sand.  And yet...  It looks more like the sand was added to hide something the rolling over maybe to destroy failed to make look "desolately natural..."

To me it looks like the sand was moved by the rock in front of it, but as I don't know in what direction was the rover moving I cannot be sure. Also, as there isn't any photo of that area from the other camera (so we could look at two perspectives and make a stereo image) there's no way of knowing if things are as they look or if it's a kind of perspective illusion, I have seen that many times in those photos.

The red arrow points to a rock formation that looks more biological in formation, but maybe it's a rock.

To me it looks just like a layered rock, like hundreds of other layered rocks that have appeared on those photos.

Here I see what could be either rocks - or painted pottery.

They didn't break like pottery when run over by the rover.
