Limestone fossils.
That said, fossil specimens in metamorphic rock are vanishingly rare and notable in even museum-grade collections. These are usually the result of some freak one-in-a-billion occurrence. For the most part, however, it can be assumed that 99.999% of fossils on the planet are contained in sedimentary stones.
The majority of limestone comes from shallow seas, which covered central Texas during the Mesozoic era when dinosaurs ruled. Bodies of sea creatures would sink to the floor when they died, and over time, only their calcium-rich skeletons or shells remained. These formed the calcium carbonate that accounts for at least 50 percent of all limestone.Type Sedimentary Rock Origin Biochemical Texture Clastic Composition Calcite Color Dark Gray Miscellaneous Visible fossils in crystalline matrix; Reacts with HCl; Hardness < Glass Depositional Environment Variable Depth Continental Shelf/Platform Marine Type Sedimentary Rock Origin Biochemical Texture Clastic Composition Calcite Color Light to Medium Gray Miscellaneous Visible fossils in ...Fossils of Ontario Identification Key and Activity If you live in Southern Ontario, there are fossils containing history from millions of years ago right under your feet!

The numerous calcareous plates make up the bulk of the crinoid, with only a small percentage of soft tissue. These ossicles fossilise well and there are beds of limestone dating from the Lower Carboniferous around Clitheroe, England, formed almost exclusively from a diverse fauna of crinoid fossils.
