text: In the geologic timescale, the Olenekian is an age in the Early Triassic epoch
or a stage in the Lower Triassic series. It spans the time between 251.2 Ma and 247.2
Ma (million years ago). The Olenekian follows the Induan and is followed by the Anisian.
The Olenekian saw the deposition of a large part of the Buntsandstein in Europe. Archosaurs
- a group encompassing crocodiles, pterosaurs, dinosaurs, and ultimately birds - are
diapsid reptiles that first evolved from Archosauriform ancestors during the Olenekian.
