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 ...
Map of Earth during the Early Permian, around 285 million years ago, showing Central Pangean mountain range at equator. The Central Pangean Mountains were formed during the collision of Euramerica and northern Gondwana as part of the Variscan and Alleghanian orogenies, which began during the Carboniferous approximately 340 million years ago, and complete by the beginning of the Permian around ...
Overview map of the peopling of the world by early humans during the Upper Paleolithic, following the Southern Dispersal paradigm. The so-called "recent dispersal" of modern humans took place about 70–50,000 years ago. [60] [61] [62] It is this migration wave that led to the lasting spread of modern humans throughout the world.
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of gymnosperms such as cycads, ginkgoaceae and araucarian conifers, and of archosaurian reptiles such as the dinosaurs; a hot greenhouse climate; and the tectonic break-up of Pangaea.
In 1972, fragmentary fossils of anatomically modern humans were found at Chouqu and Gangzilin, in Zuojhen District, Tainan, in fossil beds exposed by erosion of the Cailiao River. Though some of the fragments are believed to be more recent, three cranial fragments and a molar tooth have been dated as between 20,000 and 30,000 years old.
Soon, Pangaea began to split up and North America began drifting north and westward. During the latter Jurassic, the floodplains of the western states were home to dinosaurs like Allosaurus, Apatosaurus, and Stegosaurus. During the Cretaceous, the Gulf of Mexico expanded until it split North America in half. Plesiosaurs and mosasaurs swam in ...
Radiocarbon dating of the fossils and other artifacts in the cave suggested that these early humans were living there from around 45,000 years ago, making them the earliest Homo sapiens known to ...
