Fossil used to compare the relative ages of fossils?
Index fossils are used to compare the relative ages of fossils. These are fossils that are known to have lived during a specific time period, helping to date the rock layers in which they are found. By identifying and comparing index fossils, scientists can determine the relative ages of different rock layers and fossils.
Why are index fossils more useful then other fossils to paleontologist?
Index fossils are useful to paleontologists because they are easily recognizable, widespread, and existed for a relatively short period of time. This allows scientists to date the rock layers in which they are found, helping to establish the relative ages of different strata. Additionally, index fossils help correlate rock layers from different locations, aiding in the reconstruction of Earth's history.
What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
How are index fossils different from original fossil remains?
Index fossils are original fossil remains, just a specific subcategory of them. Index fossils are used by paleontologists to identify a particular period of time and often a subperiod of time - the specific fossil is chosen as an index fossil because it is very specific to a time period and allows the other fossils and remains around them to be identified to the same time period.
What are index fossils used to determine?
Index fossils are used to determine the relative age of rock layers. By studying the presence of these distinct fossils in different layers of rock, geologists can identify the relative age of the rocks and correlate them with other rock layers in different locations.

Principle that allows rock layers in different places to be correlated based on their fossils?
Relative dating by index fossils.

Why are index fossils are more useful to paleontologists than many other fossils?
im trying to figure that out myself
What are index fossil and how are they used to determined the absolute age of sedimentary rock?

What is fossils organisms that lived a short period of time called?
They are called index fossils.
Fossils that appear all over the world in certain rock layers are what?
Fossils that appear all over the world in particular rock layers are called index fossils. These fossils are used by scientists to correlate and date rock layers in different locations, providing insights into the Earth's geological history and past environments.
What fossil used to compare the relative ages of fossils?
An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
What is a fossil used to date surrounding rock layers called?
A fossil used to date surrounding rock layers is called a index fossil. Index fossils are particularly useful for determining the relative ages of rock layers in different locations.
