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.
Why are index useful to geologists?
they tell the absoute age of rcoks which they occur
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
Which is not a factor in a fossil organism being useful as an index fossil?
it must have lived through a long span of time
Is it true that To be a useful index fossil a species must have been rare?
False.
What is the fossil called that geologists use to determine rock ages?
Index Fossil
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 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.
Why are index useful to geologists?
they tell the absoute age of rcoks which they occur
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.
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 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
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.

False.
Why are the Eurypterids in these cross sections not useful as index fossils?
The Eurypterids in these cross sections not useful as index fossil because they are only found in certain areas are a long lived organism
