Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
Permian–Triassic boundary at Frazer Beach in New South Wales, with the End Permian extinction event located just above the coal layer [2]. Approximately 251.9 million years ago, the Permian–Triassic (P–T, P–Tr) extinction event (PTME; also known as the Late Permian extinction event, [3] the Latest Permian extinction event, [4] the End-Permian extinction event, [5] [6] and colloquially ...
The Panthalassa superocean 250 million years ago The supercontinent Pangaea in the early Mesozoic (at 200 Ma) surrounded by Panthalassa. The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago.
Pangaea's predecessor Gondwana is not considered a supercontinent under the first definition since the landmasses of Baltica, Laurentia and Siberia were separate at the time. [7] A future supercontinent, termed Pangaea Proxima, is hypothesized to form within the next 250 million years. [8]
The authors wrote that, within 250 million years, all the continents will converge to form Earth’s next supercontinent: Pangea Ultima. “A natural consequence of the creation and decay of ...
The Triassic (/ t r aɪ ˈ æ s ɪ k / try-ASS-ik; sometimes symbolized 🝈) [8] is a geologic period and system which spans 50.5 million years from the end of the Permian Period 251.902 million years ago (), to the beginning of the Jurassic Period 201.4 Mya. [9]
Ichthyosaurs, which slightly resembled modern dolphins, first appeared about 250 million years ago. Over time, some of them evolved to have larger body sizes, and by 202 million years ago, ocean ...
