- Middle Triassic
Triassic In the geologic timescale , the Middle Triassic is the second of three epoch geology epoch s of the Triassic period geology period or the middle of three series stratigraphy series in which the Triassic system stratigraphy system is divided. It spans the time between 245 1.5 annum Ma and 228 2 Ma million years ago . The Middle Triassic is divided into the Anisian and Ladinian age geology ages or stage stratigraphy stages . Formerly the middle series in the Triassic was also known as Muschelkalk . This name is now only used for a specific unit of rock strata with approximately Middle Triassic age, found in western Europe.

It spans the time between 251 0.4 annum Ma and 245 1.5 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 age geology 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 lithostratigraphy lithostratigraphic unit of continental red beds . Early Triassic life The Permian Triassic extinction event spawned the Triassic period. The massive extinctions that ended the Permian period and Paleozoic era caused extreme hardships for the surviving species. Many types of coral s, brachiopod s, mollusca molluscs , echinoderm s, and other invertebrate s had completely disappeared. The most common Early Triassic hard shelled marine invertebrates were bivalvia bivalves , gastropoda gastropods , ammonite s, sea urchin echinoids , and a few articulate brachiopod s.

The corresponding series stratigraphy series is known as the Upper Triassic . In the past it was sometimes called the Keuper , after a German lithostratigraphy lithostratigraphic group stratigraphy group a sequence of rock strata that has a roughly corresponding age. The Late Triassic spans the time between 228.0 2 annum Ma and 199.6 0.6 Ma million years ago . The Late Triassic is divided into the Carnian , Norian and Rhaetian Geologic time scale ages . Many of the first dinosaur s evolved during the Late Triassic, including Plateosaurus , Coelophysis , and Eoraptor .

A. S. author2 Schulte McMenamin, D. L. volume 43 issue 5 pages 310 ref Vertebral remains from the ichthyosaurs are arranged into almost geometric patterns that resemble the sucker discs on an octopus tentacle, leading to the contention by Mark McMenamin and Dianna L. Schulte McMenamin that the patterns represent Earth s earliest examples of self portraiture, possibly implying high intelligence in the hypothesized Mesozoic cephalopod. The vertebral centra in the Specimen U sample, for example, are arrayed in a biserial pattern, in an arrangement that differs from their original placement in the shonisaur vertebral column.
