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.
What else can I help you with?
Why are so many creatures with shells found as fossils?
because they are found by waters edge
Would You find fossils in quartz?
Quartz is a mineral not a rock. Fossils can be found associated with quartz in sedimentary rock not inside the quartz.
What are the properties of sandstone?
Sandstone is grainy, porous, and can be found to contain fossils.
What showed proof for Alfred Wegener on Pangaea?
We know Pangaea existed because of fossil evidence. There were fossils of the same animal found on Africa and South America. This animal couldn't have possibly swam across the ocean. Therefore, making the idea of Pangaea plausible.
What is the fossil that was found on different continents and was used to support the theory of continental drift?
There was a lot of fossils that were found but the most interesting one is the plant called Glossopteris, it was the only seed-fern plant fossil found.
Where cro-magnon fossils found?
Cro-magnon fossils mostly found around europe.
What kind of rock are fossils found in?
Igneous rocks.
Do swamps contain fossils?
they can, but they are mostly found underground
Fossils found in the lowest geological strata are gerenally the most?
Fossils found in the lowest geological strata are generally the oldest. This is because the law of superposition dictates that older rock layers are found at the bottom, with each successive layer above being younger. Therefore, fossils found in lower strata are older than those in higher strata.
What can you infer about the area where you find a pecten fossil?
Pecten fossils are mostly found on the east coast of the United States.
Which layer of the earth are fossils mostly found?
The crust. There are no fossils in the core as the outer core is liquid and no organisms have lived on the inner core.
Which type of rock is where fossils are found?
They are mostly found in Sedimentary Rocks
Where have dinosaur fossils been found?
Mostly around South America, Africa and Asia
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.
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.
Are fossils found in upper layers of sedimentary rocks are older than fossils found in no one there is a sedimentary rocks?
Fossils found in the upper layers of sedimentary rocks are generally younger than those found in lower layers, due to the principle of superposition, which states that in undisturbed layers, older sediments are deposited first and are buried by younger sediments. If there are no sedimentary rocks present, it is impossible to compare their ages directly. Thus, the age of the fossils can vary significantly depending on their specific geological context.
What type of water are fossils mostly found in?
Fossils are not found in water, but rather in the sediment deposits which includes the bottom of a body of water. Fossils are especially prevalent in shallow marine environments where they may become well preserved.
