Gondwanaland: A Study of the Continent in a Theoretical Sense

Gondwanaland, Science 905 Section I
In the late nineteenth century, on the basis of comparative geological evidence, the Austrian geologist, Edward Suess, founded a theory that a single supercontinent, which he called Gondwanaland, an ancient landmass that consisted of the present continents of South America, Africa, Australia, and Antarctica as well as the Indian subcontinent. Gondwanaland is believed to have been intact at least twice, about 350 million years ago and about 200 million years ago. The more specific date for the beginning of the separation of the continent Gondwanaland is around 245 to 208 million years ago.
Between these two periods all seven of the present-day continents probably formed a single landmass called Pangaea.
Gondwanaland is named after the Upper Paleozoic and Mesozoic formations of the Gondwana district of central India, which display a number of shared geologic features (the "Gondwana beds"). There are also some other evidence such as:
