Fossils

Fossils, minerals, and sediment layers are commonly found in rock formations that are millions of years old. These can provide valuable insight into the Earth's history, past climates, and ancient life forms that once existed.

Fossil fuels are formed from the remains of dead plants and animals, which undergo decomposition under high pressure, heat, and anaerobic conditions over millions of years. These three components - organic matter, heat, and pressure - are essential in the formation of fossil fuels such as coal, oil, and natural gas.

every radioactive isotope has a measurable half-life, which is the time it takes for half the original isotope to decay to something else. So if we know how much was there originally, it's easy to calculate how long it's been decaying. In many cases we also use the product of the decay, which gives us a very good way to find out how much was originally there.

Asphalt fossils are prehistoric organisms that have been preserved in asphalt or tar deposits. These fossils can provide valuable information about ancient ecosystems and species. The natural properties of asphalt can create unique conditions for preservation, including exceptional detail of soft tissues.

Sedimentary rocks form from the accumulation and cementation of sediments, which can entomb and preserve the remains of plants and animals as fossils. Igneous and metamorphic rocks form from molten material or intense heat and pressure, which would destroy any fossils present.

Shale is the sedimentary rock type that is likely to be formed in the most offshore environment. Shale is made up of fine clay particles that settle in quiet water far from the influence of waves and currents.

Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.

Corals have existed for the greatest length of time according to the fossil record, dating back over 500 million years.

Fossils found in the same rock layer or strata are assumed to be of similar age and were likely deposited during the same time period. This allows scientists to infer the relative ages of the fossils based on the layer they were found in. Fossils within the same layer can provide valuable information about the environment and species that existed during that specific time period.

Fossils of an organism that lived relatively recently would be expected to be found in younger layers of rock, as they would not have had sufficient time to become buried and fossilized in older layers. Fossils of older organisms tend to be found in deeper, older layers of rock.

Gasses produced from fossil fuels are many, such as what was known as coal gas (acetylene), CO2, CO, and many others that are formed with impurities found in fossil fuels as sulphur which can produces several toxic gasses within itself.

By examining the fossil's size, shape, and structure, scientists can infer details about the animal's appearance such as its skeletal structure, body size, and possible features like teeth or claws. Comparing these characteristics with known living organisms can help create a visual representation of the extinct animal.

The Theory of Continental drift proposed by Wegener was strengthened by the fact that Fossils of Glossopteris were found on many continents that were now far apart. Fossils of Glossopteris were found on Australia, India, South America and Africa, suggesting these were all close to Antarctica once.

Plants and animals can become fossils in sedimentary rocks because these rocks are formed from layers of sand, silt, and clay that accumulate over time, preserving the remains. As sediment builds up, it can bury dead organisms and protect them from decay, leading to the formation of fossils. The slow process of sedimentation helps in the preservation of details of the organisms, allowing researchers to study past life forms.

Fossil records of ancient elephant species, such as Mammoths and Mastodons, show the evolution of elephants over millions of years. These records demonstrate changes in size, tusk shape, and habitat preferences, reflecting the process of adaptation and evolution. Comparing these fossils to modern elephants helps scientists understand how elephants have evolved over time.

Water erosion is a type of formation that moves sediment and erodes rock. This can occur through processes such as rivers carving out canyons, waves breaking down coastlines, or glaciers scraping across land.

It can take anywhere from hours to days to find a shield fossil underground, depending on the size of the area being excavated, the tools and expertise of the individual conducting the search, and the luck in locating the fossil.

The demand for fossil fuels would need to decrease in the future to mitigate climate change and reduce greenhouse gas emissions. Transitioning to renewable energy sources is essential to combatting global warming and achieving sustainability. Additionally, the finite nature of fossil fuels and their environmental impacts necessitate a shift towards cleaner alternatives.

The fossils of Eoraptor were found by Argentine paleontologist Ricardo Martinez in the Ischigualasto Formation in Argentina in 1991. Eoraptor is an important early dinosaur from the Late Triassic period.

Stratigraphic layers can be used to determine the age of a fossil in a simple manner. The layers towards the top of an outcrop are younger (Law of Superposition and Law of Original Horizontality) and the layers near the bottom are older. If a fossil is found in a lower layer then that fossil is older than any fossils found in the higher up layers.

If you find a seashell fossil in a rock layer on a mountain, than you know that the rock layer was formed at a time when that area was submerged under water. This is because the seashell lived and died underwater, so it would have been fossilized there as the rock layer formed. Millions of years later, the water drained away, and forces within the Earth's crust pushed the rock layer and the layers above it upward, forming mountains. Of course, the rock layer would have been buried deep within the Earth by that point, but as the mountains formed, weathering and erosion would have worn away the newer layers, exposing the ancient rock layer with the seashell.

Fossils in Wizard101 can be found while completing the "Crafting Quests" at the Wizard City, Krokotopia, and Dragonspyre locations. They are typically found by digging up reagents with the "transmute" or "gardening" spells learned from the crafting quests.

This concept is known as the principle of faunal succession, which states that fossil organisms succeed one another in a definite and recognizable order. By studying the fossil assemblages found in rock layers (strata), geologists can determine the relative ages of those layers based on the organisms they contain. This principle is fundamental in stratigraphy and biostratigraphy for interpreting Earth's history.

It is not so much the fossils themselves but the fossil record that show us that the environmental conditions have changed.

The evolution of the Earth's Biosphere (living things, the oceans, land surface and atmosphere) began about 3600 million years ago when the atmosphere and oceans had no free Oxygen in them. The first life on Earth (blue green alga and 'stromatolites) slowly produced Oxygen and these are the only fossils we find from this time. As oxygen was produced over the next 3000 million years, it caused iron to be deposited out of the sea water (forming our banded Iron ore deposits) and slowly changing the atmosphere. As the Oxygen built up more complex life forms developed and by 5-600 million years ago the fossils of hard shelled sea creatures are found. Slowly more and more oxygen was released from the sea into the atmosphere and at about 425 million years ago we begin to see the fossils of the first land plants. Animals then began to follow the plants out of the seas onto land and we see fish and amphibian fossils then came the age of the reptiles (dinosaurs) and as we get nearer to the present more and more and more varied animals are found as fossils. Thus Life CREATED the Environment and the fossils prove this. They can be in cold climates or be in hot weather. It depends what their climate is. (:

Yes. The only exceptions would be if tectonic forces either overturned the rock layers through folding or if older layers were thrust on top by a thurst fault. A thrust fault would be apparent if you see the same layers repeat.
