During what era did Gondwanaland and Laurasia begin to break apart?
Gondwana ( /ɡɒndˈwɑːnə/) or Gondwanaland was a supercontinent that existed from the Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic (about 180 million years ago), with the final stages of breakup, including the opening of the Drake Passage separating South America and Antarctica …
During which era did Pangaea split?
Triassic Period
At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.

When was Pangaea united with Gondwana and Laurussia?
Palaeogeographical maps. (A,B) In the Carboniferous, Pangaea was accreted by the suturing of Gondwana and Laurussia near the palaeoequator – (A) Early Carboniferous (Mississippian), and (B) Late Carboniferous (Pennsylvanian). Pangaea was fully united during (C) the Permian and (D) throughout much of the Triassic.
Where did the landmass of Laurasia come from?
Laurasia ( / lɔːˈreɪʒə, – ʃiə / ), a portmanteau for Laurentia and Asia, was the more northern of two large landmasses (the other being Gondwana) that formed part of the Pangaea supercontinent from around 335 to 175 million years ago ( Mya ).
