How are marker beds used to determine the age of strata in a region that has no marker beds but does
contain strata with the same fossil assemblage zone? What will be an ideal response?
Marker beds are dated with radiometric techniques. Marker beds that encompass a fossil zone in one
region can then be used to define the duration of that zone in regions where the marker beds do not
occur.
