This study is called biostratigraphy. Fossils can different to match rocks of all same age, even when you how those dating a long way apart. This matching process how called correlation, dating has been an important process in constructing geological timescales. Some fossils, called index fossils, are particularly relative in correlating rocks. For a fossil to be a good index rocks, it needs to have lived during one specific time period, be easy to identify are have been abundant and found in many places.

For example, ammonites lived in the Mesozoic era. If you find ammonites in a rock in the South Island how also in a rock in the North Island, you can say that both rocks are Mesozoic. Different species of ammonites lived at different times within the Mesozoic, how identifying a fossil species different help narrow from when a rock was formed. Correlation can involve matching an undated rock with a dated one at another location.

Our Earth has been around for approximately 4. Fossils, or rocks with evidence that life, show that life formed on Earth nearly four billion years ago. The fossil record helps scientists to understand the history of change over time. We find fossils such as sea shells, imprints of plants and animals, and burrows from worms that crawled through the soil long before man existed. In the high Himalayan peaks we find fossils of life forms that lived in oceans long ago.

In many places we see evidence that the Earth’s atmosphere had to evolve before living things could live on land. In other places, the rock record reveals mass extinctions that occurred when environmental conditions changed so rapidly that organisms could not keep pace with the rate of change. All of these fossils tell us something about the evolution of life on our planet and the evolution of the planet itself. Due to the Earth’s dynamic processes life has adapted to fit available niches. Coevolution occurs between the physical and chemical interactions of Earth’s geosphere, hydrosphere, atmosphere, and biosphere.

Today, life on Earth exists in a myriad of forms and occupies a wide range of environments.

Radiocarbon dating principle is illustrated in thin layer formed first? Aleontology, and character education is illustrated in phase 1?

For students to gain an understanding of earth science concepts: properties of rocks and fossils; geological time and the history of life on Earth. BACKGROUND.

A fossil is the preserved remains of a dead organism from millions of years ago. Fossils are found in rocks and can be formed from:. Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin’s theory of evolution , which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils.

By studying fossils, scientists can learn how much or how little organisms have changed as life developed on Earth. There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began. Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

Evolutionary trees are used to represent the relationships between organisms.

The fossil record is one of the most obvious pieces of evidence for evolution. Fossils have been known since human history began, and Aristotle first noted the similarity between fossils and living animals, leading him to conclude that fossils represented deceased creatures, a view supported by Leonardo da Vinci. By the 19 th century, people were increasingly beginning to appreciate that some fossils represented extinct animals, and that their positioning in the rocks appeared to represent that passage of time.

Now there is also ample evidence from molecular genetics and radiometric dating that the fossil record does represent the evolutionary history of life on Earth. Despite this, creationists still continue to argue otherwise. Some have suggested that the fossil record represents animals killed during one or more biblical floods, however this is incongruent with the evidence available. Fossils usually only preserve certain parts such as bones, seeds, teeth and shells; parts that were mineralised prior to death.

Throughout human history, people have discovered fossils and wondered about the creatures that lived long ago. In ancient times, fossils inspired legends of monsters and other strange creatures. Another fossil reminded the Greeks of the coiled horns of a ram. Similarly, legends of the Cyclops may be based on fossilized elephant skulls found in Crete and other Mediterranean islands. Can you see why Figure Many of the real creatures whose bones became fossilized were no less marvelous than the mythical creatures they inspired Figure

Scientists use special fossils called index fossils, to date rocks. After many more half-lives, a very small amount of the original parent’s isotope remains.
