Among many methods, carbon dating is most commonly used to date fossils. In carbon dating, scientists look at how much carbon is left in the fossil, look at the half-life period, and use that to see when it was from.

∙ 12y agoFrozen fossils would need radio-uranium dating. Which you would use a trace amounts of hemophilia mixed with a vat of boiling uranium, to produce micro organisms, then you can date these organisms.

Why are their so many well-preserved fossils?
There are so many well preserved fossils because there are so many fossils, some will be well preserved. In certain locations at certain times the conditions will be right for preserving living tissues.
Which radiometric dating method would be ujsed to date objects found at effigy mounds?
Carbon-14
What are some methods of identifying the age of fossils?
it can be matched to another fossil that can be visually identified as being from the same animal, and then can be matched up to the period the animal lived...or the second method would be to do a radio carbon dating test....but the fossil would have to be fairly old because the carbon dating can tell you how old something is within a few thousand years.
How is the relative age of fossils determined?
It is generally determined by how long it has waisted away or if it has reached a certain disintegrating phase (an example would be a half-life). By learning how long a fossils minerals and dead cells have wasted away biologists can learn how old a fossil is relative to a period or our own time on earth.
What are fossils used to determine the relative ages of rock layers?
The age of a fossil would ordinarily be considered the age of the rock in which it was entrained. A common exception is where burrowing organisms, such as snails and worms, excavate their way into a soft rock. But even in these cases, their age would not be too different (in geological terms) from the rock age. The age of a rock may be determined by radio isotope dating, or more commonly and cheaper, by stratigraphy.
To determine the absolute age of rocks and fossils geologists use?
They would look for evidence of index fossils, those of certain rapidly evolving creatures that lived during a specific time period. This method is called relative dating. For a closer estimation they would be able to date the rock using radiometric techniques that base its age on the degree of isotope decay . This method would reveal the much more specific absolute age.
Why would uranium-238 not be useful in determining the age of a spear that is thought to be 5000 years old?
Uranium dating is useful for long periods of time - e.g. 109 years. For fossils is recommended the method with 12C.
How do people know dinosaurs lived?
Our most provident evidence would be carbon dating and fossils.
Why would a scientist use both relative and absolute dating?
They both help you understand fossils
Which radiometric-dating method would be most apprioate for dating artifacts found at effi gy mounds?
Carbon-14 dating would be the most appropriate radiometric dating method for dating artifacts found at effigy mounds. This method is commonly used for dating organic materials such as wood, charcoal, or bone, which are typically found in archaeological sites like effigy mounds.

Radiocarbon dating would be useful in dating the age of the earth?
Radiocarbon dating is not typically used to determine the age of the Earth because it can only accurately date organic materials up to around 50,000 years old. Other dating methods, such as radiometric dating of rocks and minerals, are used to estimate the age of the Earth, around 4.5 billion years.
How would a geologist determine the age of rock layers and fossils if the geologist found a never before seen rock layer that contain fossils?
First step would be relative-dating: examining the new unit in the context of known rocks above and below it. Then look for correlative formations & fossils elsewhere.
What method would archaeologists use to date the remains of cro-magnons?
Radiocarbon dating.
Who Preserved remains of ancient organisms?
it depends on how and were they died for example plants turn into peat, then coal animals turn into fossils if they died in the mud or sand animals or plants that are frozen would keep their hair and organs and shape both plants and animals, if nothing happened and they were left out to the elements, would just disintegrate and rot in time
Which isotope would you use the estimate something that was about 1 million years old?
The method of uranium-lead dating.
Which radiometric dating method would be ujsed to date objects found at effigy mounds?
Carbon-14
