To enter the fossil record is even harder. Scientists can look at patterns in the fossil record to understand the history of life on earth. The fossil record provides a powerful basis for analyzing the controlling factors and impact of biological evolution over a wide range of temporal and spatial scales and in the context of an evolving earth. Fossils are traces of organisms that lived in the past. So most of the fossils we find are shells, bones and woody tissues.
Paleontologists have recovered and studied the fossil remains of many thousands of organisms that lived in the past. What is left is a mineral impression of an animal which once existed. Usually only a portion of an organism is preserved as a fossil, such as body fossils (bones and exoskeletons ), trace fossils (feces and footprints), and chemofossils (biochemical signals). Web a new analysis of fossils belonging to an extinct invertebrate called rotadiscus grandis have helped place this species in the animal tree of life, revealing how some characteristics of living species may have evolved independently rather than originating in a single common ancestor.
The answer lies in the fossil record. When these hard materials are covered. So most of the fossils we find are shells, bones and woody tissues.
