Dolomite rock (or dolostone) is, by definition, made of over 50% calcium-magnesium carbonate (the mineral dolomite), usually in the form of well-defined crystals. Some calcite is also possible as a remnant of the dolomite’s precursor, limestone. Fossils are common in dolomite, especially sea shells and coral.

Footprints, worm burrows, and insect nests are examples of trace fossils. Sedimentary rock contains fossils because it was built up layer upon layer, often trapping and preserving animals, plants, footprints, and more within the layers of sediment.
Limestone is a sedimentary rock that is typically white, gray, or tan in color, but it can also be found in various shades of blue, green, pink, or red. It is often composed of small fossils or shell fragments, indicating that it formed from the accumulation of calcium carbonate-rich marine organisms, such as coral, shellfish, and algae.Look for sedimentary rocks: Fossils are typically found in sedimentary rocks, which are formed by layers of sediments. Look for rocks such as limestone, sandstone, shale, or mudstone, as these are more likely to contain fossils.
