Conceptual schematic showing the resolution of stratigraphic units in fast- and slow-racemizing genera.
(A) wide separation of three hypothetical units using fast-racemizing genera
(B) resolution of the same units with slower racemizing genera
(C) lack of resolution likely with unsuitable, relatively slow-racemizing genera
