A footprint which has hardened in the cement. 7 A dinosaur left its footprints in the mud, and the mud turned to rock. This is atrace fossil. Some ancient animals, like dinosaurs may have walked across wet mud and left footprints in the mud, like in the picture below. The dinosaur leaves a trace behind. Over millions of years, this footprint can be preserved and become a trace fossil. QUESTIONS Use the diagram below as well as your previous knowledge of how sedimentary rock forms to write captions for each stage of the formation of atrace fossil. 152 Earth and Beyond 8
Trace fossils were also made from animals nests, eggs and droppings. Teacher's Note A body fossil would be in the form of the organism that has fossilized. A trace fossil indicates evidences other than afossilized body part, that indicates the existence of an organism, such as burrows, trails, eggs, nests, and fecal matter (dinosaur poop). Some fossils of ancient organisms look similar to plants and animals that are alive today. Picture of some marine fossils which look very similar to the shells we get today. 9 4.3 Importance of South African fossils Did you know that South Africa is world famous when it comes to important fossil finds?
