Fossil crinoids indicate that the rocks containing their remains were formed in a marine environment and, where abundant in Palaeozoic rocks, they suggest the former existence of shallow water conditions. In the early Carboniferous, their rich remains (particularly stem fragments) were solidified into rock called crinoidal 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. How Fossils Form. 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.Trace fossils such as Conostichus, Zoophycus, and Asterosoma are most commonly found in sandstone and siltstone of this region.
