Would you mind putting a little text on? Dimensions, what you think it is, how you found it, more precise place than Alberta, too vast territory...

 

What do you want to be guessed from just pictures like these without any explanation ?

 

As far as I’m concerned, I don’t see any fossils in there.

A big rock. And check your spelling.

The lighter colored features to the left in the top photo may be brachiopods. Concretions actually seems more likely though. 

The feature seen top center in the second photo is a fracture pattern. 

If you're going for stegosaurus, that's a hard no.
