The range of a fossil species refers to the span of time during which the species existed on Earth. It is determined by the oldest and youngest known occurrences of that species in the fossil record. The range provides information about the species' period of existence and can be used to study evolution and environmental changes over time.
If you mean the Fossil Maniac, then he lives just to the west (left) of Fallabor Town.
The relative age of a fossil that can be determined by comparing it to an index fossil is called biostratigraphic dating. This method relies on the known age range of the index fossil to estimate the relative age of the fossil being studied.
The fossil record is incomplete.
