  1. Triassic

    The Triassic is a geologic period and system that extends from about 250 to 200 Ma. It is the first period of the Mesozoic Era, and lies between the Permian and Jurassic periods. Both the start and end of the period are marked by major extinction events. The Triassic was named in 1834 by Friedrich von Alberti, after the three distinct rock layers that are found throughout Germany and northwestern Europe—red beds, capped by chalk, followed by black shales—called the "Trias." The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it would take well into the middle of the period for life to recover its former diversity. Therapsids and archosaurs were the chief terrestrial vertebrates during this time. A specialized subgroup of archosaurs, dinosaurs, first appeared in the Late Triassic but did not become dominant until the succeeding Jurassic. The first true mammals, themselves a specialized subgroup of Therapsids also evolved during this period, as well as the first flying vertebrates, the pterosaurs, who like the dinosaurs were a specialized subgroup of archosaurs. The vast supercontinent of Pangaea existed until the mid-Triassic, after which it began to gradually rift into two separate landmasses, Laurasia to the north and Gondwana to the south. The global climate during the Triassic was mostly hot and dry, with deserts spanning much of Pangaea's interior. However, the climate shifted and became more humid as Pangaea began to drift apart. The end of the period was marked by yet another major mass extinction, wiping out many groups and allowing dinosaurs to assume dominance in the Jurassic.

Examples of Triassic in a Sentence

  1. Sam Heads:

    Insect fossils of this type, preserved in three-dimensions like this, are practically unheard of from the Triassic, so this discovery is very important.

  2. Lindsay Zanno:

    People don't think about how many different predators were around in the Triassic, and that crocs really ruled before dinosaurs.

  3. Brandon Peecook:

    The existence of Antarctanax in the early Triassic implies that all these other crazy lineages must have existed at this point already, even if we dont have a good fossil record of them from this time.

  4. Paul Barrett:

    These types of tracks are not particularly common worldwide, so we believe this is an interesting addition to our knowledge of Triassic life in the UK. The record of Triassic dinosaurs in this country is fairly small, so anything we can find from the period adds to our picture of what was going on at that time.

  5. Cindy Howells:

    We know this dinosaur is (was born) 200 million years ago, to within half a million years or so, the rocks down here we've been studying for quite a long time now and we can do direct comparisons with the ages of rocks in Austria, which is where the transition between the Triassic and the Jurassic boundaries is precisely located.
