insert Definition (id: null
text: The Early (Lower) Triassic is the first of three epochs of the Triassic Period
of the geologic timescale. It spans the time between 251.902 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 Buntsandstein, a lithostratigraphic unit of continental
red beds.
