How does the law of superposition allow paleontologist to assign relative ages to fossils?
The law of superposition states that the lower down the layer of rock (also called strata) in the ground, the older it is. Therefore, if the fossil is located in a specific strata that is a certain depth beneath the ground it is conclusive as to about how old the fossil is.
How does the law of superstition date fossils?
The law of superstition, also known as the law of superposition, states that in undisturbed sedimentary rock layers, older layers are found below younger layers. This principle helps paleontologists date fossils by examining their positions within these layers. If a fossil is found in a lower layer, it is considered older than fossils found in higher layers. Thus, the relative age of fossils can be determined based on their stratigraphic context.
What can cause older fossils to be found on top of yonger fossils?
This situation can occur due to natural geological processes such as faulting or erosion, which can disrupt the original sequence of deposition. These processes can result in older rock layers ending up on top of younger ones, creating an apparent inversion of the typical order of fossil accumulation. It is important for paleontologists to consider these geological factors when interpreting the sequence of fossils in a particular area.
Is aragonite more likely to be found in younger or older fossils?
Aragonite is more likely to be found in younger fossils. This is because aragonite is a less stable form of calcium carbonate compared to calcite, which tends to recrystallize into calcite over time in older fossils.
Why are the oldest fossils sometimes not on the bottom layers of rocks?
Older fossils may not always be found at the bottom layers of rocks due to geological processes like folding, faulting, or erosion, which can disrupt the original order. In these cases, older fossils may be found at higher layers while younger fossils are found in lower layers.
Why do you read the time scale starting at the bottom?
We read the Geologic timescale from the bottom to the top because, that is the same way geologists and paleontologists had found the older fossils. The older fossils lay at the bottom, and the more younger ones, near the top.
How the law of superposition helps paleontologist?
Superposition is the methodology of younger sediments being deposited over older rocks. Paleontologists can determine the evolution or extinction of a species by looking at what fossils are either present or absent in a particular sedimentary layer.
What is the importance of the works of a paleontologists?
The importance of the works of a paleontologists is to find out how earth was like & to let people learn about the importance of it & to find out the fossils of plants and animals long long time ago, so that they would teach other people to learn about them so if they would want to know about them they know what is the answer to their question.People also this as their job cause they also want to learn the importance of the works of a paleontologists.These people who are now paleontologists knows everything from the past & maybe they would teach the younger kids to learn about them & see how fun & exciting it is to be a paleontologists.

Younger fossils and not older fossils are more like?
this is an incoherent question that cannot possibly be answered
What are the difference between reworked fossils and leaked fossils?
From the law of faunal succession,older beds are characterized by fossils of older age and the younger beds are characterized by younger age fossils.But in some exceptional condition the younger fossils are reported in the older formation and those are termed as leaked fossils. whereas,Fossils of older age occur in younger rock are known as reworked fossils.They are derived from the older rocks by reworking ad recycling of sediments.
Where are older fossils mostly found under or above younger fossils?
If the rocks containing the fossils have been involved in a mountain building episode they would be folded and if some of the folds were laid in a recumbent position and later eroded you would have older above younger rocks. Of course, it would be easy to find out if this was the case because of the various sedimentary structures in each separate layer of rock.
Why would fossils found at the top of a canyon probably be younger than those found at the bottom of the canyon?
The fossils found at the top of a canyon will probably be younger than those at the of the bottom of the canyon because the fossils at the bottom of the canyon would have been there earlier when the so called "canyon" was once a flat land, so as time went by, the flat land began growing and getting taller and finally became a canyon so the fossils at the top of the canyon WOULD be younger than those at the bottom because the bottom fossils were there before the top of the canton even existed.
Is aragonite more likely to be found in younger or older fossils?
Aragonite is more likely to be found in younger fossils. This is because aragonite is a less stable form of calcium carbonate compared to calcite, which tends to recrystallize into calcite over time in older fossils.
What evidence is there that earth has had a succession of flora and fauna?
Fossils!Fossils are the 'remains' of plants and animals (including humans) which lived in the past. Millions of fossils have been found all over the world. They show clearly that different species of plants and animals lived in the past and that they changed over long periods of time. Older fossils are simpler than younger fossils and we can work out the sequence of evolution from these fossils.For example the oldest vertebrate (backboned) fossils are fish. Younger than these are the first amphibians. Then reptiles appear as fossils, followed by birds and mammals.See:http://animals.about.com/od/evolution/a/vertebrateevolu.htmhttp://txtwriter.com/Backgrounders/Evolution/EVpage01.htmlhttp://evolution.berkeley.edu/evosite/lines/Ifossil_ev.shtmlhttp://www.fossilmuseum.net/
How are sedimentary layers used to date fossils?
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.
