Why is fossil evidence in rocks older that 600 million years old compared with the number of fossil found in younger rocks?

WELL...
Due to the fact that organisms of that period of time and earlier were small, not abundant and soft bodied. Adding in the rock cycle with its weathering, erosion, subduction, melting and so on affects the fossils that are 600million years are scarce.

Abundant fossil evidence did not appear in the geologic record until about?
Geologic records evidence of abundant fossil is 540 Million Years ago during the Paleozoic Era.
When did abundant fossil evidence appear in the geologic record?
540 Million years ago
What are the three pieces of evidence that supports continental drift theory?
Climate fossil and fossil climate
What is a primary fossil fuel that releases the fewest pollutants when compared to other fossil fuel?
Natural gas.
Which rocks give the most reliable radiometric date?
Relative dating of rock involves an approximation of age based on fossil evidence found in a rock formation. The type of evidence found can be compared to the geologic time scale, a range of eras or periods in which the fossil can be found. Absolute dating of rock involves the scientific measurement of radioactive element decay and is fairly precise.
Abundant fossil evidence did not appear in the geologic record until about?
Geologic records evidence of abundant fossil is 540 Million Years ago during the Paleozoic Era.
On what continent was the earliest fossil evidence of human found?
the first fossil was found 2.6 million years ago and was a spearhead
What is the earliest known evidence of people using roses?
The rose is, according to fossil evidence, 35 million years old.
When did abundant fossil evidence appear in the geologic record?
540 Million years ago
When did abundant fossil evidence appearing the geologic record?
540 Million years ago
What percent of geologic time is represented by abundant fossil evidence?
The planet Earth is about 4,600 million years old. Fossil evidence becomes abundant in the geological record in the Cambrian Era, which was about 550 million years ago (when hard shelled animals appeared) Therefore (550/4600)*100 = roughly 12% of Geological time contains abundant fossil evidence. However, please note that (non abundant) fossil evidence goes back about 3600 million years, (3600/4600)*100 = roughly 73% of Geologic time.
When did abundant fossil evidence first appear in the geologic record?
The first abundant fossil evidence first appeared during the Paleozoic Era. It was the first era of the Phanerozoic Eon, which occurred 540 million years ago.
When did man first walks on two legs?
4.2 to 3.9 million years ago (oldest fossil evidence)
What are the raccoon's ancestors?
Fossil evidence shows that the raccoon family first developed in Europe 25 million years ago.
When there is a significant lack of fossil evidence in the Earth's rock beds from a specific time period after 544 million years ago what do scientists believe has taken place?
544 million years ago was the Proterozoic era. This was before visible life on the planet. This long ago the inhabitants wouldn't necessarily leave a fossil. If there is a lack of fossil evidence after this that means there was a mass extinction in this part of the world, and nothing survived to have children to leave fossils. Eventually another species will migrate in but until that happens there would be no fossil evidence.
How long has the raccoon been around?
The first fossil evidence of the raccoon family was found in Europe and dates back 25 million years.
What evidence supports his hypothesis?
The evidence that supports wegeners hypothesis is the fossil evidence
