Paleontology, palaeontology or palæontology (from Greek: παλαιό (palaeo), "old, ancient"; όν (on), "being"; and logos, "speech, thought") is the study of prehistoric life forms on Earth through the examination of fossils.^[1] This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised faeces (coprolites), palynomorphs and chemical residues. Studies of prehistoric hominins, their culture and their behaviour are the purview of two other disciplines, archaeology and paleoanthropology.
