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.

How are index fossils useful to geologist?
Index fossils provide a reference of time throughout rock layers. In order to be a good index fossil, the life form must have lived for a short and specific amount of time and must have existed over a large area. Index fossils serve as a reference to geologists in correlating rock layers. They can match up (or correlate) the index fossils which helps them match up (or correlate) the rock layers.

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 three conditions may a fossil meet in order to be an index fossil?
An index fossil must be widely distributed, allowing it to be found in various geographic locations. It should also have a short geological time range, meaning it existed for a relatively brief period in geological history. Lastly, an index fossil needs to be easily recognizable and distinct from other fossils, aiding in the identification of specific time periods in the geological record.
How are fossils organized in the fossil record?
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.
What have Mass extinctions determined?
order in which fossils are found in the fossil record.
What three features must a fossil have a order to be an index fossil?
* the organism must be common in rocks from most of the world *the organism must have lived for only a geologically short period of time( a few million years to a few hundred million years) *the organism must be easy to identify.(trilobites and ammonites are 2 kinds of organisms that are used as index fossils).

How do you get both fossils in Pokemon Black?
The only way to get both Generation 5 fossils as in the Cover Fossil which is also the Tirtouga Fossil and the Plume Fossil, also known as the Archen Fossil, you will need to trade with another player in order to receive the other Fossil. Fossils in Pokémon Black can be attached to any Pokémon that you're trading.
How can fossils be used to date the rock in the strata?
Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.
