A fossil that is used to date surrounding rock layers is?
This is called an index fossil.
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.
Why are the soft parts of a plant or animal found in fossils?
Fossils are preserved traces of organisms from the past. The totality of fossils, both discovered and undiscovered, and their placement in fossil-containing rock formations and sedimentary layers (strata) is known as the fossil record. The study of fossils across geological time, how they were formed, and the evolutionary relationships between taxa (phylogeny) are some of the most important functions of the science of paleontology. Such a preserved specimen is called a "fossil" if it is older than some minimum age, most often the arbitrary date of 10,000 years ago.
What is the geologic law that scientists use to date the crust by studying the layers of rocks called?
The law of superposition states that the oldest strata in an undisturbed formation of rock are the oldest.
What is the best way to measure the date when the displacement of a fault occurred?
date only the bottom soil layers on both sides of the fault.

What kind of rock layers did index fossil date?
index fossils are used to date the rock layers they are found incc
What is the legislation called that defines principles surrounding a practices code of ethic and confidentiallity?
what is the legislation called that defines the principles surrounding a practise code of ethics and confidentiality and what date did it come into action
What are geologists able to tell archaeologists about fossils?
How do archaeologists date fossils ? archaeologist can date fossills by seeingf how deep down it is in the ground [ checking how many layers ] , scientists can use radio-active dating, and compare a fossil that they know the exact date that it was from compare the looks and tell by that

The first dinosaur fossil and the fossil on Vega island in 1986 were representatives of what geological time period?
The first dinosaur fossil ever found in Antarctica is called Antarctopelta. Its fossils date to the late Cretaceous period. Cryolophosaurus, the first theropod discovered in Antarctica, date back to the early Jurassic period.

How do you change the date on a Fossil FS4735 watch?
Changing the date on a fossil watch is easy. All you have to do to change the date is turn the right hand knob on the watch.
How do archaeologists date fossils?
Scientists take samples of the carbon remaining in the fossil. They then use a form of carbon dating to determine its age. (it doesn't have to be a fossil, it could be any ancient remain, even a skull from fifty years ago, or a plate from the 1700's. Just wanted to clarify that a little bit more!)
How can you date the layers of the earth?
by asking yourself
Why do you need fossil fuels?
Because to date there is no viable alternative to fossil fuels, that are plentiful and cost effective.
