Palaeos Mesozoic : Triassic : Olenekian |
 | | The Olenekian Age is named for the Олениок River in Siberia, where the type section occurs, and which we have probably spelled incorrectly. |
| | The beginning of the Olenekian (Induan - Olenekian boundary) is marked by the first appearance of the conodont Neospathodus waageni. |
| | Another indicator is a magnetostratigraphic shift from reversing polarity in the Late Olenekian to a long normal zone in the Early Anisian. |
