Fossils are the remains and traces ( such as footprints or other marks) of ancient plant and animal life that are more than 10,000 years old. They range in size from microscopic structures to dinosaur skeletons and complete bodies of enormous animals. Skeletons of extinct species of humans are...
Latin word “fossilis”, which means, “dig up”. Fossils can be divided into “body fossils” and “trace(痕迹) fossils”. Body fossils are the remains of a plant or animal’s body. Trace fossils are the remains of the activity of an animal, such as footprints, egg shells, and ...
Trace fossils usually show tracks that animals made while moving across soft sediment. This sediment later hardens to become sedimentary rock. Trace fossils are valuable to palentologists because by studying these footprints, scientists can discover how the animals moved, which in turn gives important...
Fossilsgenerally form either as mold fossils or as cast fossils and are either considered a trace fossil or a body fossil. An imprint or the natural cast of a footprint in rock is an example of a mold fossil and a trace fossil, while a mineral deposit in the shape of a shell is an ...

Stories about dinosaurs have existed for as long as people have been aware of the existence of trackways and fossils. Some researchers suggest that legends of behemoths and dragons come from the discovery of dinosaur bones and footprints [source: Sanz]. There are also cave paintings that appear...
We passed handmade stick lettering, five feet high and designed from large pieces of driftwood, stuck into the sand bars asking visitors to “leave nothing but footprints” and a peace symbol, made alike, a short distance away. Some four wheeling tourists who pass thru seem hellfire bent on ...

It is a fascinating branch of biology that solves mysteries of fossils. Ichnologists followplants and animalfootprints in an attempt to reconstruct a sequence of events to identify organisms long dead. It is multi-discipline encompassing paleontology, biology, sedimentology, stratigraphy, pedology, and...
