yes
Fossils are arragned in sequential order because of the buildup of material over the top of them for millions of years. Hence, the oldest will be on the bottom. This can be altered by certain geoligical processes and will depend on the rockbed and formation present in the area.

The range would be the span of time between the point in the geologic record the fossil organism first appeared to the point in the geologic record that the organism last appeared.
