postTriassic

postTriassic is a term used to describe the geological time period that followed the Triassic period. This encompasses the Jurassic and Cretaceous periods, which together form the Jurassic-Cretaceous period or Mesozoic Era. The Triassic-Jurassic extinction event marked the boundary between the Triassic and Jurassic periods. During the post-Triassic era, dinosaurs continued to diversify and dominate terrestrial ecosystems. Pterosaurs ruled the skies, and marine reptiles such as ichthyosaurs and plesiosaurs thrived in the oceans. The Jurassic period saw the breakup of the supercontinent Pangaea, leading to the formation of new oceans and changing continental configurations. This period is also characterized by the evolution of early birds, such as Archaeopteryx. The Cretaceous period witnessed further diversification of plant life, including the rise of flowering plants (angiosperms). This era concluded with the Cretaceous-Paleogene extinction event, which famously wiped out the non-avian dinosaurs and many other species, paving the way for the Cenozoic Era. The study of post-Triassic fossils provides crucial insights into the evolution of life on Earth and the dynamic geological history of our planet.
