To be useful as an index fossil fuel spices must have existed for how long?
To be useful as an index fossil fuel, spices must have existed for about 1000 years.
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 3 requirements do index fossils have?
To be an index fossil, it must be widespread, commonly found (sometimes in groups) and have a short life span for which it lived. If a fossil meets all three of these requirements, it is considered an index fossil.
What are the three criteria that must be met in order for a fossil to be considered an index fossil?
An index fossil is organisms that is a signature for certain geographical eras. Index fossils are a charting of time that is used to describe other organisms found in that time era. The fossils were found in the stones that are determinations by carbon indexing and therefore are index fossils.
What is an organism used to identify a specific geologic time period called?
An organism used to identify a specific geologic time period is called an index fossil. Index fossils are used by geologists to narrow down the age of rocks and sediment layers based on the known age range of the fossil species.
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 three conditions must a fossil meet in order to be an index fossil?

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.

Which is the index fossil of paleocene?
The index fossil commonly associated with the Paleocene epoch is Pleuraspidotherium, a genus of mammals belonging to the order Condylarthra. This organism is significant for paleontologists as it helps to identify and date Paleocene deposits in the fossil record. Other notable index fossils from this period include certain species of foraminifera and mollusks, but Pleuraspidotherium is particularly recognized for its role in biostratigraphy.
What is fossils organisms that lived a short period of time called?
They are called index fossils.
What must be true for a fossil organism to be useful as a index fossil?
