Many fossil trackways were made by dinosaurs, earlytetrapods, and other quadrupeds and bipeds on land. Marine organisms also made many ancient trackways (such as the trails of trilobites and eurypterids like Hibbertopterus).

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 κόπρος (kopros, meaning "dung") and λίθος (lithos, meaning "stone").]]> 2018-01-23 16:47:03 UTC https://padlet.com/3049101/hmt7b0ljihld/wish/223874422 3049101 https://padlet.com/3049101/hmt7b0ljihld/wish/223875540 A true form fossil is a fossil of the whole/entire body of the organism, like an actual animal or animal part. True form fossilsare formed when the animals soft tissues or hard parts did not decay over the years.
