GENERAL GEOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Pangea was the last supercontinent, a giant conglomeration of all the continents. It formed 300 million years ago when the tectonic plates that make up Earth’s crust modified and rearranged themselves, bringing the continents together.

Detailed explanation-3: -About 200 million years ago, all the continents on Earth were actually one huge “supercontinent” surrounded by one enormous ocean. This gigantic continent, called Pangaea, slowly broke apart and spread out to form the continents we know today. All Earth’s continents were once combined in one supercontinent, Pangaea.

Detailed explanation-4: -Early Gondwana (pre-Pangea, 550-336 mya) 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: -Life on dry land included bacteria, fungi, plants, insects, amphibians, reptiles, saurians, the early mammals, and the first birds. All of this variety evolved over hundreds of millions of years (technically billions if you count the earliest life forms).
