What is the best evidence that many different geologic periods are represented in Virginia?
The presence of fossils of different ages
Paleontologists noticed that these were the same on different continents even though the continents were separated by ocean?
The same rocks and minerals from the same batch, dinosaur fossils dating back to the same time periods, natural landforms and structures can be found on completely separate continents. This evidence supports the Plate Techtonics and Continental Drift theories.
The sum of all the fossils that exist is called the?
The sum of all the fossils that exist is called that fossil record. It includes fossils from all geologic time periods.
What is a fossil that can be used as a marker in time called?
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived (in geological terms, lasting a few hundred thousand years), then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution-otherwise the likelihood of finding and recognizing one in the two sediments is minor. --- Wikipedia
Why are fossils important to evolution?
Fossils give a record as to what organisms lived throughout different time periods. Generally speaking, the lower layers of soil show the oldest fossils, which aids scientists in following the progression of evolution of an organism. Also, radioactive carbon dating is used in dating how old a fossil is by finding the amount of carbon^14, and then calculating how many half lives have passed to reach this amount.

What would the fossils tell you about the history of that area?
If you found a fossil, and you knew which animal it were and how it prefered to live. You could tell how the weather was, if the area was covered with trees, or a more desert-like area- dependant on how the animal lived. Maybe even compare it to other fossils, to give a more precise estimate on how it was back in the day. By looking at different fossils from different time periods, you would be able to see the development of the area trough the ages.
What qualifications do archaeologists need?
Archeology is a subject studied at university (or college). It often includes courses in different periods, excavations, preserving, handling material and so on. In some countries and areas it's possible to join groups of amateur archaeologists who helps out the actual archaeologists on excavations without an education.
How paleontologists use trilobite use fossils as index fossils for various geologic time periods?
yeah

How is a tyrant different from ancient Greece then today?
Well, that would be hard to compare, because two different lifestyles from two different time periods are not remotely the same.
What are the geologic periods named from?
Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.
Why do archaeologists classify the artifacts they find?
Archaeologists classify artifacts to organize and categorize them based on their characteristics, such as material, style, function, and cultural context. This classification helps researchers analyze and interpret the artifacts to better understand past human societies and behaviors.
The sum of all the fossils that exist is called the?
The sum of all the fossils that exist is called that fossil record. It includes fossils from all geologic time periods.
Which are the remains of species that existed on Earth for relatively short periods of time were abundant and were wide spread geographically?
They are called index fossils, an aid to relative dating of rock.
Are index fossils the remains of species that existed on earth for relatively short periods of time?
yes
How much are cd rates at banks?
There are many different factors that determine the interest rates on a bank CD. A good place to check is Bankrate.com where you can compare rates today for different periods of time.
