What is a tropites fossil?
A tropites fossil is a fossil of a tropites. A tropites is a genus of coiled ammonite. They only existed for about 20 million years, which makes it a good index fossil.
To compare the relative ages of fossils scientists sometimes use an easily recognized species called?
To compare the relative ages of fossils, scientists use an early recognized species called an index fossil. An index fossil must have existed for a short period time and must have covered a wide geographical range.
What are four advantages for fossil fuels?
four advantages for fossil fuels: Fossil fuels have high energy density, are readily transportable, are usable with current infrastructure, and
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 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)
What are the 3 characteristics of index fossils?
Index fossils help scientists figure out the plants and animals that were alive in a certain time period. There are different types of index fossils that are used for different amounts of time.
What are some index fossil characteristics?
It must be distinct from other organisms. It must have lived in a very wide geographic region
Which characteristics of a fossil would you make it useful as an index fossil in determining the relative age of widely separated rock layers?
C). a narrow time range and a wide geographic range
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?
The absolute age of the index fossil was determine by radioactive dating or another absolute method

hiii
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 is the index fossil of the Cambrian?
Trilobite
Fossil used to compare the relative ages of fossils?
index fossils
Which New York State index fossil may have been present in a rock layer that is missing due to the unconformity?
