Some things about that photo:
- colourising a photo removes some information about the image, as you turn it into a monochrome image
- images that size will always be hard to analyse
- we don't really know how a Martian fossil looks like
But yes, generally it would be something like that.
But for most of us this would still look like rocks. Unless the rock is excavated and analyzed, it will remain a rock no matter how closely it
looks like a dinosaur.
It depends, after all, we only pick the rocks that look unusual, we don't pick all the rocks when we are looking for fossils.
Unless we have an army of paleontologists on Mars, we have no option but to depend on the expert opinion of NASA scientists (who I believe are
not paleontologist of any measure) and the findings of their tests and instruments which sometimes is called one for the "History Books" and then
repudiated a few days later.
I don't think they have palaeontologists on the Curiosity team, but a geologist is enough to "filter" some of the cases. After all, a fossil can
only be part of a sedimentary rock or be a mineralized version of the original, fossils do not exist in igneous rocks like basalt, for example.
Another example of a fossil found on our planet earth which too look like a bunch of rocks except for people with "pareidolia"
Context is important. If I saw something like this on a Mars photo I would probably say that they look like rocks but that they would look out of
place in an area like all those we have seen so far, without rocks that look like that.
After all, fossils are rocks.
