What are index and what do geologists learn from them?
Index fossils are very important to geologists because they identify geological. The fossil snail is a particularly difficult animal to study.
What methods did geologists use when they first developed the time scale?
The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide. By Patrick
What information can index fossils give geologists?
Index fossils can tell scientists if an animal or plant was alive in a certain period of time. They may also tell scientists what time period a certain rock layer formed.
What do scientists use index fossils for?
Geologists use index fossils to define and identify geologic periods.
How can fossils be used to date the rock in the strata?
Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.

Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
What are index fossils useful for?
Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.
In what type of rocks would geologists most likely find evidence of past life forms?
Index Fossils
What type of rocks would geologists most likely find evidence of past life forms?
Index Fossils
How can fossils be used to date rocks?
Geologists look for index fossils in the sedimentary rock to help determine its age. Index fossils are of organisms that were widespread and only existed during a specific slice of geologic time. Finding an index fossil in a rock means that the rock dates to that specific slice of time.
How are index fossils used by uniformitarian geologists?
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
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 are index fossils useful to geologist?
Index fossils provide a reference of time throughout rock layers. In order to be a good index fossil, the life form must have lived for a short and specific amount of time and must have existed over a large area. Index fossils serve as a reference to geologists in correlating rock layers. They can match up (or correlate) the index fossils which helps them match up (or correlate) the rock layers.
