The Continent Original acrylic on canvas painting by Betsy Heilman Some million years ago all the world's land masses were beginning to form into one supercontinent, Pangaea, surrounded by a single universal sea, Panthalassa.
The vast supercontinent of Gondwana was centred over the South Pole. The concept that all of the continents of the Southern Hemisphere were once joined together was set forth in detail by Alfred Wegenera German meteorologist, in He envisioned a single great landmass, Pangaea or Pangea.
Gondwana comprised the southern half of this supercontinent. Du Toit carefully documented the numerous geologic and paleontological lines of evidence that linked the southern continents. This evidence included the occurrence of glacial deposits— tillites —of Permo - Carboniferous age approximately million years old and similar floras and faunas that are not found in the Northern Hemisphere.
The widely distributed seed fern Glossopteris is particularly cited in this regard. It also occurs in the Maitland Group of eastern Australia as well as in the Whiteout conglomerate and Polarstar formations of Antarctica. Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the Late Carboniferous.
Included in the paleogeographic reconstruction are cold and warm ocean currents. The present-day coastlines and tectonic boundaries of the configured continents are shown in the inset.
Scotese, The University of Texas at Arlington According to plate tectonic evidence, Gondwana was assembled by continental collisions in the Late Precambrian about 1 billion to million years ago.
Gondwana then collided with North AmericaEuropeand Siberia to form the supercontinent of Pangea. The breakup of Gondwana occurred in stages. At about the same time, India, which was still attached to Madagascar, separated from Antarctica and Australia, opening the central Indian Ocean.
India eventually collided with Eurasia some 50 million years ago, forming the Himalayan mountains, while the northward-moving Australian plate had just begun its collision along the southern margin of Southeast Asia—a collision that is still under way today.
Present-day coastlines and tectonic boundaries of continents are shown in the inset at the lower right.According to plate tectonic evidence, Gondwana was assembled by continental collisions in the Late Precambrian (about 1 billion to million years ago).
Gondwana then collided with North America, Europe, and Siberia to form the supercontinent of Pangea. The breakup of Gondwana . Honoring the ancient supercontinent, Pangea Aerospace has been created by gathering international engineers together under a common objective.
During Earth’s long history, there probably have been several Pangea-like supercontinents. The oldest of those supercontinents is called Rodinia and was formed during Precambrian time some one billion years ago. Another Pangea-like supercontinent, Pannotia, was assembled million years ago, at the end of the Precambrian.
Alfred Wegener () developed the theory of continental draft, and he coined the term "Pangea" for the supercontinent representing the original state of all the earth's continents.
In his. In addition to the DB8 supplementary spreadsheet, a KML file (for importing data into a mapping applications, such as Google Earth) contains most of the data associated with DB8 sampling.
Earth's continents during the Carboniferous Period were arranged differently than they are today. South America, Africa, India, Australia, Antarctica, and a few minor pieces were joined together near the south pole to comprise the supercontinent known as Gondwanaland..
