TriasJurakauden

TriasJurakauden refers to the geological period encompassing the Triassic and Jurassic periods. These two consecutive geological periods represent a significant era in Earth's history, spanning from approximately 252 to 145 million years ago. The Triassic period, the first epoch of the Mesozoic Era, followed the Permian-Triassic extinction event, the most severe extinction in Earth's history. This period saw the gradual recovery of life and the rise of new dominant groups, including the first dinosaurs. The climate was generally hot and dry, with a single supercontinent, Pangaea, dominating the globe.

Following the Triassic, the Jurassic period commenced. This era is often considered the "golden age of dinosaurs," as many of the most iconic and largest dinosaur species, such as Brachiosaurus and Allosaurus, roamed the Earth. Pangaea began to break apart during the Jurassic, leading to the formation of new oceans and influencing global climate patterns. Large marine reptiles like ichthyosaurs and plesiosaurs thrived in the oceans, and the first birds, such as Archaeopteryx, are believed to have evolved during this time. The TriasJurakauden as a combined concept highlights the continuous evolutionary and geological developments that occurred across these two formative periods of the Mesozoic.
