Paleontologists look for index fossils in fossil bearing sedimentary rock. Index fossils are organisms that were widespread, rapidly evolving, and only existed for a short period of time as evidenced by their appearance in the fossil record of specific rock strata. The appearance of a fossil alongside an index fossil gives a rough approximation of the age of the fossil in relative terms as it would appear on the geologic time scale. The appearance of the same fossil alongside index fossils of different geologic ages means that the fossil organism spanned multiple geologic time periods. Associations of specific strata alongside radiographically datable igneous and metamorphic rock determines the absolute age of a fossil.
Fossils in the fossil record are typically organized based on the time period they existed in, starting from the oldest at the bottom and the most recent at the top. This helps scientists understand the history of life on Earth and how species have evolved over time. Fossils can also be organized based on similarities in their physical characteristics to track evolutionary relationships.
Fossils are arragned in sequential order because of the buildup of material over the top of them for millions of years. Hence, the oldest will be on the bottom. This can be altered by certain geoligical processes and will depend on the rockbed and formation present in the area.

What do scientists use the fossil record for?
Recording fossils No.
What are traces or remains of organisms that lived in the past?
Fossils are proof of organisms that lived long ago
How does the fossils record arganize fossils?
The fossil record is thought to organize things in age order with the older rocks behind at the bottom and newer rocks being at the top.
Use fossils in a sentence?
Fossils of dinosaurs are found by paleontologists, maybe one day one will find a fossil of you From: Waqar Moghul * A mature answer would be: The Blue- Jay is a particular species of bird
All fossils that scientists have collected create the?
Fossil record, which provides a timeline of life on Earth and helps scientists understand the evolution and diversity of organisms over time.
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.
The fossil record is?
a record that shows how fossils have changed over time
How are fossil organized in the fossil record?
The fossil record organizes fos- sils by their estimated ages and physical similarities.
What do scientists use the fossil record for?
Recording fossils No.
Do fossil records help to date fossils?
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.
What is a record fossil?
A fossil record is a historical sequence of life indicated by fossils found in layers of Earth's crust.
What have Mass extinctions determined?
order in which fossils are found in the fossil record.
The total collection of all the fossils in the world is called the?
Fossil Record
Can fish have fossils?
Yes, hundreds of species of fish can be found in the fossil record.
Sentence with the word trace fossils?
a fossil record shows what types of fossils there are
What are traces or remains of organisms that lived in the past?
Fossils are proof of organisms that lived long ago
How does the fossils record arganize fossils?
The fossil record is thought to organize things in age order with the older rocks behind at the bottom and newer rocks being at the top.
