What name is given to fossils that are widespread geographically?
Fossils that are widespread geographically are commonly referred to as cosmopolitan fossils. These fossils are found in multiple locations around the world, indicating a broad distribution during the time period in which they were alive.
Can fossils be used as index fossils?
Yes, index fossils are special fossils that act as geological tools enabling comparison in time of a range of geological units and environment. Normally, they are selected using certain attributes such as the fossil should be widespread, abundant, fast evolving, and independent of their environment.
What is the relative age of fossils found at the top layer of rock?
They are called index fossils, fossils of organisms that were widespread, evolving quickly, and only appeared in the geologic column for a specific length of time.
Which are the remains of species that existed on earth for relatively short periods and were abundant and widespread geographically?
Fossils of index fossils, which are species that lived for short periods and were widespread geographically, are commonly used in stratigraphy to date and correlate rock layers. These species are useful markers because they can be found in multiple locations and help determine the age of the rock layers they are found in.
Are index fossils easily recognizable?
Yes, index fossils are typically easily recognizable because they are common, widespread, and distinct in appearance. These fossils are used as markers for specific time periods in geological strata due to their unique characteristics.

What name is given to fossils that are widespread geographically are abundant in number and limited to a short span of time?
Index Fossils
What is meant by paeleontology?
study of fossils and dinosaurs
What fossils are most useful for correlation tend to be?
Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.
Can fossils be used as index fossils?
Yes, index fossils are special fossils that act as geological tools enabling comparison in time of a range of geological units and environment. Normally, they are selected using certain attributes such as the fossil should be widespread, abundant, fast evolving, and independent of their environment.
What is the name of the fossils that are widespread geographically and are limited to a short span of geologic time?
Index Fossils. They are very important tools for geologists and used in paleontology and stratigraphic studies.

How index fossils can be used to determine the age of rocks?
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.
What fossils are the remains of species that existed abundantly on earth for relatively short periods of time widespread areas?
Index Fossil
Explain how an index fossil can be used date rock.?
Index fossils are fossils of organisms that lived for a relatively short period of time but were widespread geographically. By identifying these index fossils in a particular layer of rock, scientists can determine the age of the rock and correlate it with other rock layers containing the same index fossils. This allows for the relative dating of rock layers based on the presence of specific index fossils.
