Detailed explanation-1: -From about 300-200 million years ago (late Paleozoic Era until the very late Triassic), the continent we now know as North America was contiguous with Africa, South America, and Europe. They all existed as a single continent called Pangea.

Detailed explanation-2: -Pangaea. This illustration represents Pangaea, the supercontinent that existed about 225 million years ago, a time when the dinosaurs were first establishing themselves as a life form on Earth.

Detailed explanation-3: -Looking at the continents he theorized that they had once been joined together as a supercontinent around 225 million years ago. This continent was later named Pangaea. Did you know? The name Pangaea comes from the Ancient Greek words “pan, ” meaning entire, and “Gaia, ” meaning Earth.

Detailed explanation-4: -Early Gondwana (pre-Pangea, 550-336 mya) It didn’t contain all land on Earth, or even close to it, really. Nearly of Earth’s modern southern hemisphere landmasses were part of Gondwana. In addition, the Arabian peninsula, North Africa, and the Indian subcontinent were part of Gondwana.

Detailed explanation-5: -About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Laurasia was made of the present day continents of North America (Greenland), Europe, and Asia. Gondwanaland was made of the present day continents of Antarctica, Australia, South America.
