Mesozoic.

Reptile - Evolution, Paleontology, Adaptation: The first land vertebrates, the Tetrapoda, appeared near the middle of the Devonian Period. The earliest known reptiles, Hylonomus and Paleothyris, date from the Late Carboniferous. The Mesozoic Era is known as the “Age of Reptiles.” Today's reptiles represent only a fraction of the reptile groups and species that have lived..

248 to 206 Million Years Ago. In many ways, the Triassic was a time of transition. It was at this time that the world-continent of Pangaea existed, altering global climate and ocean circulation. The Triassic also follows the largest extinction event in the history of life, and so is a time when the survivors of that event spread and recolonized.The Mesozoic Era [3] is the second-to-last era of Earth's geological history, lasting from about 252 to 66 million years ago, comprising the Triassic, Jurassic and Cretaceous Periods. It is characterized by the dominance of archosaurian reptiles, such as the dinosaurs; an abundance of gymnosperms, (such as ginkgoales, bennettitales) and ferns ...Mesozoic. In the Triassic the Ceratite beds, named after the ammonite ceratite, consist of arenaceous limestones, calcerous sandstones and marls. The Jurassic consists of two distinct units. The Kioto limestone, extends from the lower the middle Jurassic with a thickness 2,000 feet (610 m) to 3,000 feet (914 m).

Frequently, there is a slender layer of clay between the final layer of Cretaceous rock and the initial layer of Cenozoic rock.

The main Mesozoic geology in South China is characterized by reworking of ancient continental margins to intracontinental tectonics, lacking oceanic arc basalts and continental arc andesites.

During the Mesozoic, Pangaea began separating into the modern continents, and the modern Rocky Mountains rose.

The oldest dated metamorphic sequence in Alaska, the fault-bounded Kilbuck Terrane, consists of continental rocks that were metamorphosed under amphibolite-facies conditions during early Proterozoic (1.77 Ga) time. Proterozoic or early Paleozoic metamorphic ages are also possible for greenschist- and amphibolite-facies continental rocks in interior Alaska (Ruby and Nixon Fork terranes).At least two Tethyan seas successively occupied the area between Laurasia and Gondwana during the Mesozoic Era. The first, called the Paleo-Tethys Sea, or Paleo-Tethys Ocean, was created during the convergence of all landmasses into what would become the supercontinent of Pangea late in the Paleozoic Era. During the Permian and …
