Siberia (continent) the Carboniferous Period, it collided with the minor continent of Kazakhstania. A subsequent collision with Baltica during the Permian completed the formation of the supercontinent Pangaea. The Siberian Traps formed. Pangaea split up during the Jurassic though Siberia stayed with Laurasia. Laurasia gradually split up during the Cretaceous with Siberia remaining part of present-day northeastern Eurasia. Today, Siberia forms part of the minor supercontinent of Afro-Eurasia. In around 250 million years from now Siberia may be in the subtropical region and part of a new supercontinent of Pangaea Ultima. Siberia (continent) Siberia, also known as Angaraland (or simply Angara) and
Pangaea closing the Paleo-Tethys Ocean, but forming a new ocean, the Tethys Ocean, in its southern end. Most of the landmasses were all in one. By the Triassic Period, Pangaea rotated a little and the Cimmerian plate was still travelling across the shrinking Paleo-Tethys, until the Middle Jurassic. The Paleo-Tethys had closed from west to east, creating the Cimmerian Orogeny. Pangaea, which looked like a "C", with the new Tethys Ocean inside the "C", had rifted by the Middle Jurassic, and its deformation is explained below. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that
