What is fossils organisms that lived a short period of time called?
They are called 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 is fossil form a specific time period?
Index fossils (also known as guide fossils, indicator fossils or zone fossils).
What does it mean when fossils have been called the index to earth history?
viusualize it back from it;s time period
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.

What is fossil form a specific time period?
Index fossils (also known as guide fossils, indicator fossils or zone fossils).
What are the remains of species that existed on Earth for a short period of time?
index fossils
Why are trilobite consider index fossils?
they were index fossils because they were found everywhere, had distinct characteristics, and lived for a short period of time.
The fossils of organisms that were widely distributed but only lived during a short period of time are called?
They are called index fossils.
What does it mean when fossils have been called the index to earth history?
viusualize it back from it;s time period
What criteria are used to identify index fossils?
An index fossil must be of a rapidly evolving organism that only existed for a specific period of time, is easily recognizable, is abundantly preserved, and was widespread geographically. Most index fossils are therefore of marine organisms.
Do index fossils tell the relative or absolute age of fossils?
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 do geologists use index fossils to determine rock age?
Index fossils, also known as zone or guide fossils, help date strata and sediment to determine the age of entrapment. The best index fossils are those that were abundant , common, and short lived.
