A coprolite is fossilized animal dung. Coprolites are classified as trace fossils as opposed to body fossils as they give evidence for the animal's behaviour (in this case diet) rather than morphology. The name is derived from the Greek words kopros meaning 'dung' and lithos meaning 'stone'. They were first described by William Buckland in 1829. Prior to this they were known as fossil fir cones and bezoar stones. They serve a valuable purpose in palaeontology because they provide direct evidence of the predation and diet of extinct organisms. Coprolites may range in size from a few millimetres to over 60 centimetres.Coprolites distinct from paleofaeces are fossilized animal dung. Like other fossils coprolites have had much of their original composition replaced by mineral deposits such as silicates and calcium carbonates. Paleofaeces on the other hand retain much of their original organic composition and can be reconstituted to determine their original chemical properties
