The Early Triassic is the first of three epochs of the Triassic period of the geologic timescale. It spans the time between 252.2 ± 0.5 Ma and 247.2 Ma (million years ago). Rocks from this epoch are collectively known as the Lower Triassic, which is a unit in chronostratigraphy. The Early Triassic is the oldest epoch of the Mesozoic era and is divided into the Induan and Olenekian ages.
The Lower Triassic series is coeval with the Scythian stage, which is today not included in the official timescales but can be found in older literature. In Europe, most of the Lower Triassic is composed of so-called Buntsandstein, a lithostratigraphic unit of continental red beds.

Famous quotes containing the word early:
“Long before I wrote stories, I listened for stories. Listening for them is something more acute than listening to them. I suppose it’s an early form of participation in what goes on. Listening children know stories are there. When their elders sit and begin, children are just waiting and hoping for one to come out, like a mouse from its hole.”
—Eudora Welty (b. 1909)
