The map should be changed so that organisms

are at the same latitude.

The land broke apart and moved drastically.

Australia may have rotated 180 degrees.


All of Earth’s continents

were once part of an enormous, single landmass.

which broke apart to form the continents we know today.

Fossils of similar organisms across widely disparate continents

encouraged the theory of a "supercontinent".


"Fossils of the ancient reptile mesosaurus

are only found in southern Africa and South America."



The presence of mesosaurus, a freshwater reptile only 3 feet long,

suggests a single habitat with many lakes and rivers.

Plant fossils from the frigid Arctic archipelago of Svalbard, Norway

were not the hardy specimens adapted to survive in the Arctic climate.

These fossils were of tropical plants,

which are need a much warmer, more humid environment.

The presence of these fossils suggests Svalbard once had a tropical climate.


The stratigraphy of different rocks and mountain ranges

of the east coast of South America and the west coast of Africa

seem to fit together like pieces of a jigsaw puzzle,

and their rock layers “fit” just as clearly.

South America and Africa were not the only continents with similar geology.

the Appalachian Mountains of the eastern United States,

are geologically related to the Caledonian Mountains of Scotland.

Pangaea existed about 4 thousand years ago.

This supercontinent broke up and separated into pieces that moved away from one another

and assumed their positions as the continent we recognize today.


One element lacking in the theory of continental drift

is the mechanism for how it works.

Why did the continents drift and what patterns did they follow?


About 4 thousand years ago

God confounded the language (in the days od Peleg)

and broke the land up in to separate places.

It all happened quickly.

Frozen woolly mammoths have beed found "with sub-tropical vegetation in their mouths."
