Gondwanaland: A Study of the Continent in a Theoratic Sense.

Gondwanaland, Science 905 Section I

In the late nineteenth century, on the understructure of comparative geological render, the Austrian geologist, Edward Suess, arrangeed a theory that a single super classic, which he called Gondwanaland, an ancient landmass that consisted of the present continents of southmost America, Africa, Australia, and Antarctica as well as the Indian subcontinent. Gondwanaland is believed to have been entire at least twice, about 350 one thousand thousand years agone and about 200 million years ago. The more specialised date for the seed 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 likely formed a single landmass called Pangaea.

Gondwanaland is named after the stop number Paleozoic and Mesozoic formations of the Gondwana district of central India, which display a number of sh bed geologic features (the Gondwana beds). There are overly some other evidence such as:

        the incident of tillites (glacial deposits) of 286 million years ago (the Permo-Carboniferous)

         alike plants and animal fossils are found in them but not in the blue Hemisphere, in particular the widely distributed seed fern Glossopteris

The rocks that contain this evidence are called the Karoo (Karroo) System in southeasterly Africa, the Gondwana System in India, and the Santa Catharina System in South America.

The official definition of Gondwanaland is found on the www.



thefreedictionary.com site which is as follows:

Noun         1.         Gondwanaland - a hypothetical continent that (according to plate tectonic theory) broke up later into India and Australia and Africa and South America and Antarctica

Edward Suess noted that all four continents have similar glacial deposits and fossils corresponding to the end of the Carboniferous Period and the beginning of the Permian Period (about 290 million years ago). However, these glacial deposits and fossils are absorbed from the...
