A fossil is any remains or trace of an ancient organism. Fossils include body fossils, left behind when the soft parts have decayed away, as well as trace fossils, such as burrows, tracks, or fossilized waste (feces) (Figure 11.4). Figure 11.4: Coprolite (fossilized waste or feces) from a meat-eating dinosaur. Sample of fossiliferous limestone. Fossiliferous limestone is any type of limestone, made mostly of calcium carbonate (CaCO 3) in the form of the minerals calcite or aragonite, that contains an abundance of fossils or fossil traces.The fossils in these rocks may be of macroscopic or microscopic size.

Marble is usually light colored and is composed of crystals of calcite locked together like pieces of a jigsaw puzzle. Marble may contain colored streaks that are inclusions of non-calcite minerals.Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.A fossil (from Classical Latin fossilis, lit.
