Answer for screen readers
The eon with very little fossil information due to preservation issues is the Precambrian.
More Information
The Precambrian eon, which encompasses the time from Earth's formation about 4.6 billion years ago to the start of the Cambrian Period, is poorly represented in the fossil record due to the predominance of soft-bodied organisms and significant geological changes.
Tips
A common mistake is confusing the Precambrian with specific periods within it like the Archean or Proterozoic. However, it includes all time before the Cambrian explosion.
