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 life form that lived during the Paleozoic period is an important index fossil?
The life forms that lived during the Paleozoic are Permian, the Carboniferous, (both the Mississippian and the Pennsylvanian), the Devonian,the Silurian, the Ordovician, the Cambrian, and the Precambrian. The Paleozoic Era lasted from 570 to 225 Million Years Ago. Complex forms of life appear. During this 345 million year period, plants and animals underwent rapid evolution.The Paleozoic era lasted about 345 million years. It includes the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. Index fossils of the first half of the Paleozoic era are those of invertebrates, such as trilobites, graptolites, and crinoids. Remains of plants and such vertebrates as fish and reptiles make up the index fossils of the second half of this era.
What fossil used to compare the relative ages of fossils?
An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
How long must a species have existed to be an index fossil?
The length of time is not as critical as the traits of being widespread, rapidly evolving, and observable only during a specific period of time.

How paleontologists use trilobite fossil as index fossil for various geologic time period?
yeah

A fossil with wide distribution which flourished during a specified era can be used as an?
index fossil
What characteristics must a fossil have to be useful as an index fossil?
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.
What makes a species a good index fossil?
An index fossil is used as an indicator of which era/epoch was preserved. The major characteristic necessary to be an index fossil include abundance, widely distributed, but lived for a short period of time.

What is an organism used to identify a specific geologic time period called?
It's called an index fossil.
What are three requirements for a fossil to be an index fossil?
Index fossilsFossils of organisms that lived during a relatively short geologic time span.The three conditionsTo be an index fossil, a fossil organism must be found throughout the world. It must be easy to identify and many fossils of that organism must exist.-Haileybh"I hope it helped you!"
