The mid Mesozoic saw the supercontinent Pangaea begin riftin

The mid Mesozoic saw the supercontinent Pangaea begin rifting into two landmasses, Laurasia to the north and Gondwana to the south. The age of this time period is:

Select one:

a. 250 - 350 Ma

b. 23 – 66 Ma

c. 146 – 250 Ma

d. 66 – 146 Ma

Solution

a. 250-350 Ma

Around 335 to 250 million years ago, Gondwana and Laurasia joined together to form the supercontinent Pangaea, which existed until approximately 215 to175 million years ago. Gondwana then separated from Laurasia (the mid-Mesozoicera) in the breakup of Pangaea, drifting farther south after the split. Gondwana itself then also broke apart.
