The Early Triassic (also known as Lower Triassic, Buntsandstein, or Scythian) is the first of three epochs of the Triassicperiod. It spans the time between 251 ± 0.4 Ma and 245 ± 1.5 Ma (million years ago). The Early Triassic is divided into the Induan and Olenekianfaunal stages. The word epoch can mean either an interval of time, or a particular point in time used as a reference point. ... The Triassic is a geologic period that extends from about 245 to 202 million years ago (mya). ... The table and timeline of geologic periods presented here is in accordance with the dates and nomenclature proposed by the International Commission on Stratigraphy. ... Mega-annum, usually abbreviated as Ma, is a unit of time equal to one million years. ... Jump to: navigation, search The Olenekian (also known as the Yongningzhenian) is a stage of the Early Triassic epoch. ... Faunal stages are a subdivision of geologic time used primarily by paleontologists who study fossils rather than by geologists who study rock formations. ...
The later EarlyTriassic (Olenekian age) Archosauriform Garjainia, a member of the family Eyrthosuchidae.
And in the arid climes of the early Mesozoic, the reptiles had an obvious metabolic advantage, despite the superior locomation and care of young behavior of the mammals.
The Triassic was named in 1834 by Freidrich Von Alberti[?] for the three distinct layers of redbeds, capped by chalk, followed by fl shales that are found throughout Germany and Northwest Europe.
The Triassic is the first Era of the Mesozoic Era -- the Age of Dinosaurs.
The first Angiosperms (flowering plants) may have evolved during the Triassic as did the first flying vertebrates although the latter appear to be flying reptiles, not ancestors of birds.
