Fossils are essentially plant and animal matter that have been replaced with stone over time, leaving a solid stone that appears like the original plant or animal matter.
Fossilized leaves, petrified wood, and small oceanic creatures are common.
Fossilized bone is the most common animal remains with most other parts of the animal carcass decaying very quickly. But, they are somewhat rarer than the leaves & small marine animals.
Keep in mind that multi-million year old fossils are extremely fragile and should only be handled by experts.
Fossils can often be dated by determining the age of the soils surrounding them.
Many species of animals have come and vanished on earth over the centuries and millenia. And the animal species, including man, that have survived, have changed over time.
The fossils provide a record of the species that have existed in the past, as well as providing additional support for Darwin's theory of evolution by demonstrating changes to various species over time.
A few species including Mammoths have been found locked in ice and have been preserved virtually intact for thousands of years as frozen specimens, finds that can be extremely exciting.
What else can I help you with?
Fossils such as trilobites that can be used to estabish the age of rocks are called?
I think they are called Index Fossils...
How are index fossils used by uniformitarian geologists?
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
How are fossils used in determining the age of the Earth?
Index
Why do you thank fossils are found near areas where there used to be water?
because most fossils are sea creatures, that are by the sea :)
How are fossils used?
Fossils are used by scientists to answer questions about species and maybe even dinosaurs. They use the fossils and run tests by using there DNA and seeing their molecular structure and running it by other animals for similarity's.
What is the most characteristic feature of sedimentary rocks that is used to interpret earth's history?
Fossils are the most characteristic feature of sedimentary rocks used to interpret Earth's history. They provide valuable information about past environments, climate conditions, and the evolution of life on Earth. By studying fossil assemblages within sedimentary rocks, scientists can reconstruct the geologic timeline and infer important events that have occurred in the past.
How can you use fossils and geologic features interpret the relative age of rock layers?
Fossils can be used to determine the relative age of rock layers by comparing the types of fossils found in different layers. Fossils of organisms that existed for a short period of time can be used to date layers of rock containing them. Geologic features such as fault lines and unconformities can also help determine the relative age of rock layers by showing where layers have been disturbed or eroded.
What does this information tell you about the geologic history of those areas?
Plant life could be used to interpret the geologic history of a location.
What do scientists observe to help them interpret Earth's geological history?
Scientists observe rock layers, fossils, and other geological features such as faults and folds to interpret Earth's geological history. These observations help scientists understand the sequence of events that have shaped the Earth over millions of years. Additionally, isotopic dating techniques and geochronology are used to determine the ages of rocks and the timing of key geological events.
What can rock fossils and original remains show about earths past?
it can show the futur
How can scientists use fossils to determine environmental change?
fossils are used to determine the history of changes in environment and organisms because to see how they lived long ago on the environment and things like that
Fossils that appear all over the world in certain rock layers are what?
Fossils that appear all over the world in particular rock layers are called index fossils. These fossils are used by scientists to correlate and date rock layers in different locations, providing insights into the Earth's geological history and past environments.
What are fossils are used for?
Animals or people in the pastPlants can also produce fossils; the general answer is, fossils are the remains of ancient organisms.They are dead plants and animals thathave been traped for millions of years. Humans are animals too.
What is used to measure earths history?
Scientists use various methods to measure Earth's history, including radiometric dating of rocks, analysis of fossils in sedimentary layers, and study of ancient climate data preserved in ice cores and ocean sediments. These techniques allow scientists to piece together a timeline of Earth's geological and biological evolution over millions of years.
How are fossils used to helps understand the history of earth?
Scientists can use fossils to learn about what happened about what Earth was like in the past. A fossil is any evidence A fossil is any evidence that life once existed in a place.
Why fossils are important discoveries?
Fossils provide a record of past life forms and environments, helping scientists understand evolution, ecosystems, and Earth's history. They can also provide insights into the behavior, anatomy, and physiology of ancient organisms. Additionally, fossils are used as evidence to support scientific theories and reconstruct past environments.
What we're land Bridges used as an explanation for?
