Could Curiosity's instruments discern the difference between a rock and a fossil?
ChemCam is Curiosity’s coolest bit of science gear, shooting laser beams that deliver a million watts of power for about five one-billionths of a second. The rover analyzes the resulting glowing plasma to determine what elements and molecules make up its target.

Well, what's needed for fossilization?
1)The organism must be buried quickly. For this to happen, the organism normally must die in abnormal conditions such as in a flood, volcano eruption or an earthquake. Otherwise it is near impossible for an animal to be preserved;
2)The organism must be kept from normal decay. If the animal is exposed to oxygen or bacteria, they will quickly start to decay;
3)The organism must be buried in matter that is leached with mineral-rich waters where carbonates are precipitating. These minerals will replace the original tissue, so that a stone remains in the shape of the original tissue.
Also, too many naysayers are just saying "I'm afraid they're just rocks..." How do you know? Give me one solid reason why you think that. Case in point:
Alligator Coprolite fossils
If these were shot on Mars, all the rocktards would naturally be shouting the same thing. If you want to prove they're NOT rocks, give a good reason. There are plenty of explanations/pictures so far to support the possibility of fossilization, but nothing but nonsensical posts arguing the negative.

Like many others have said, I am usually firmly in the "it's a rock" camp, but not this time. Those pics look enough like fossils to warrant further investigation, in my opinion.
