Final answer:
The super-continent called Pangaea existed during the late Paleozoic and early Mesozoic eras, encompassing all major land masses before splitting into Laurasia and Gondwana.
Step-by-step explanation:
The name of the super-continent that existed during the late Paleozoic and early Mesozoic eras is Pangaea. This vast landmass aggregated in the Permian period and included all of Earth's major land masses. It began to separate into smaller supercontinents, Laurasia and Gondwana, and eventually into the individual continents we recognize today. During its existence, Pangaea's configuration significantly influenced both the climate and the distribution of flora and fauna, setting the stage for evolutionary patterns that emerged following its breakup.
