Laurasia

  1. During the Silurian era, the continents of North America, Baltica and Siberia reassembled into the supercontinent of Laurasia [the Old Red continent].
  2. In the Cretaceous, the minor supercontinent Laurasia rifted into the continent North America and the minor supercontinent Eurasia.
  3. The Reelfoot Rift is an ancient failed continental rift which dates back to the Precambrian break-up of the supercontinent Rodinia. (Web site)
  4. By the end of the Silurian period, the northern supercontinent of Laurasia had been formed.
  5. The most prevalent Phanerozoic glaciation occurred during the Carboniferous–Permian on the Southern Hemisphere Gondwana supercontinent. (Web site)

Ordovician

  1. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia.
  2. Devonian palaeogeography The southern continents remained tied together into the Supercontinent Gondwana. (Web site)
  3. At the end of Ordovician times, the Gondwana supercontinent was situated close to the South pole (Figure 2).
  4. Although the crust of the continents is thick, it breaks more easily than oceanic crust, and supercontinents broke quickly into smaller pieces.

South America

  1. Laurentia) and South America (the northern end of Gondwana) was closed, and finally, those continents collided and became part of the supercontinent Pangaea.
  2. At that time the continents of Australia, South America, and Antarctica were just starting to break off from the southern supercontinent of Gondwana.
  3. Nena was an ancient minor supercontinent that consisted of the cratons of Arctica, Baltica, and East Antarctica[ 1]. (Web site)

Rodinia

  1. The eight continents that made up Rodinia later re-assembled into another global supercontinent called Pannotia and, after that, once more as Pangaea. (Web site)
  2. A supercontinent that existed in the Late Precambrian and gave rise to the continents of Gondwana, Laurentia, Siberia, and Baltica in the Cambrian. (Web site)
  3. Ur joined with the continents Nena and Atlantica about one billion years ago to form the supercontinent Rodinia. (Web site)
  4. Gondwanaland, also known as Gondwana, was the southern supercontinent formed after Pangaea broke up during the Jurassic period. (Web site)
  5. Other cratons and continent fragments drifted together near the equator, starting the formation of a second supercontinent known as Euramerica.

Tethys Ocean

  1. Around 200 million years ago, the Laurasia supercontinent split completely, forming Laurentia (now America) and Eurasia continents. (Web site)
  2. First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana.
  3. In the eastern hemiphere, on either side of the Paleo-Tethys Ocean, there were continents that were separated from the supercontinent.

Triassic Period

  1. This divergent boundary first formed in the Triassic period when a series of three-armed grabens coalesced on the supercontinent Pangaea to form the ridge.
  2. Nevertheless, the era featured the dramatic rifting of the supercontinent Pangaea.
  3. In the early Cambrian, the supercontinent Pannotia broke up and Avalonia drifted off northwards from Gondwana.
  4. Glossopteris was a dominant plant in Gondwana (the southern supercontinent) early in the Triassic period.
  5. During the Devonian Period, the region lay at the bottom of a shallow inland sea about ten degrees north of the equator in the supercontinent of Euramerica.

Continental Drift

  1. Pangea formed during the late Paleozoic Era when several smaller continents collided, welding together to form a single supercontinent. (Web site)
  2. The ideas of continental drift and the existence of a supercontinent (Pangaea) were presented by Alfred Wegener in 1915. (Web site)
  3. Between around 250 and 180 million years ago, it formed part of the single supercontinent 'Pangea'.

  2. In North America, the assembly of this supercontinent culminated in the closure of the Rheic Ocean and the formation of the Appalachians and Ouachitas.

Carboniferous

  1. The Carboniferous was a time of active mountain-building, as the supercontinent Pangaea came together. (Web site)
  2. We are entering a new phase of continental collision that will ultimately result in the formation of a new Pangea supercontinent in the future. (Web site)
