The question really is; If there was an ancient Martian civilization and there well could have been. How do we look for it without invoking pareidolia (s.p.)? How do Archaeologists look for ancient civilizations without succumbing to this dreaded curse? Aren't we supposed to be looking for anomalies, artifacts and such, presenting them for review and discussing them? Isn't that how science works?

That is what I am trying to point out to you, there is no 'rectangular extension' on the left hand side. There is however a light grey segment of rock half diamond shape in front of the dark rock, partially concealing the dark rock, that light grey piece of rock is also casting its own shadow and adding to the illusion. Actually the grey rock I'm talking about is really a protruding part of the dark rock that is catching the daylight, not concealing it.

Hi Amazing! Absolutely, "we'll never know from this picture alone".

ArMaP, do you have any thoughts relative to the shadow that is under the elongation? While it is not very seeable in your pics, in the OP magnification pics it is very obvious. Yet, when looking at it, it is hard to find what object is responsible for that shadow.

OK, so we know that we are both talking about the same thing, which shadow are you talking about?

It would be easier if you posted an image with that area marked in some way.
Is it the area in yellow in the image below?

I don't see anything strange with the shadow, it looks to be in the right place for being the shadow of what looks to me like the topmost rock of the group.

I think that shadow is just the left side of the rock to the right of the shadow. As light is coming from the top and a little from the right, that shadow is not as dark as real shadow as it's just an unilluminated face of the rock.
That's what it looks to me, after looking at the 3D images (I used the cross-eye version, the one I find most effective for me).
Curiosity is due to turn its drill again in this mudstone for further analysis before climbing out of Yellowknife Bay and heading for the crater's big central mountain, Aeolis Mons (Mount Sharp).
But almost as soon as it starts that journey, the robot is going to stop at some of the most spectacular rocks seen so far on the mission. Scientists have mentioned the so-called Shaler outcrop but haven't yet spoken about it in great detail.
