How paleontologists use trilobites fossils as index fossils for various geologic time periods?
Trilobites were rapidly evolving and widespread marine organisms that spanned a number of geologic time periods. Certain types of trilobites only appeared in specific segments of geologic time; therefore, when one of these trilobites is found, you can be certain that the rock layer it is found in is of a certain geologic age.
What is the during which geologic period did all three fossils form?
To accurately answer your question, I would need to know which specific fossils you are referring to, as different fossils can originate from various geologic periods. If you provide the names of the fossils or their characteristics, I can help identify the geologic period during which they formed.
These are plant and animal remains used to define and identify geologic periods?
These plant and animal remains are known as fossils. Fossils provide crucial insights into the Earth's biological history and are used by geologists and paleontologists to define and identify specific geologic periods. By studying the distribution and characteristics of these remains, scientists can establish a timeline of life on Earth and understand the evolution of species over time. Fossils also help in correlating rock layers across different regions, aiding in the reconstruction of past environments.
What are the geologic periods named from?
Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.
How do scientist contribute to the geologic time scale?
Paleontologists search for fossils to help them to determine what types of organisms lived in the same locations and at the same time. They use major changes in the fossil record to divide geologic time into large chunks.The geologic time scale is divided into: eons (biggest), eras, periods, epochs (smallest).Earth's history is divided into four major periods, from oldest to most recent: Precambrian, Paleozoic, Mesozoic, and Cenozoic

What is the best evidence that many different geologic periods are represented in Virginia?
The presence of fossils of different ages
The sum of all the fossils that exist is called the?
The sum of all the fossils that exist is called that fossil record. It includes fossils from all geologic time periods.
What information does the geologic time scale provided and what are the major divisions of time?
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
What information did geologist use to develope geologic time scale?
Radiometric dating and association of fossils with time scales during the periods when life existed.
Compare geologic time with geologic column?
Geologic time refers to the vast expanse of time over which Earth's history is recorded, characterized by different eons, eras, periods, and epochs. The geologic column, on the other hand, is a hypothetical representation of the Earth's rock layers and the fossils they contain, arranged in chronological order based on relative dating principles. Geologic time provides the framework for understanding the sequence of events in Earth's history, while the geologic column is a visual representation of this history based on the rock layers and fossils found in stratigraphic succession.
Was the 19th century the geologic time scale was based primarily on sequence of fossils in the rock record?
Yes, the 19th century was a pivotal time for developing the geologic time scale, largely based on the sequence of fossils found in the rock record. Paleontologists like Charles Lyell and Richard Owen utilized fossil assemblages to define different geological periods, establishing a framework that correlated rock layers with specific time intervals. This fossil-based approach allowed scientists to understand Earth's history and the evolution of life over time.
