Limestone origins. Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that occurred in the geological past, often tens to hundreds of millions of years ago. Species changed over time, but similar fossils can be found in most of the marine-based rocks at Grand Canyon. Stromatolites The oldest fossils at Grand Canyon are 1,200 million to 740 million years old. Stromatolites are the limestone structures formed by photosynthesizing bacteria called cyanobacteria.
