The theory of continental drift was first proposed in 1915 by Alfred Wegener, a geologist and meteorologist from Germany, and published in his book entitled 'On the Origin of Continents and Oceans'. The theory of continental drift states that parts of the Earth's crust slowly drift atop a liquid core. Detailed records of fossils belonging to every geological age in the Earth's history were kept, and these were used by Wegener as evidence to support and give credibility to his theory of continental drift and plate tectonics.

To prove the theory, he hypothetically suggested that a large super-continent, which he called Pangaea (meaning 'All-Earth'), existed more than 200 million years ago. The shift of the tectonic plates below the Earth's surface caused Pangaea to drift and break up into two smaller super-continents which were known as Laurasia and Gondwanaland during the Jurassic period and then further into separate land masses that roughly look like the modern-day continents of the world during the Cretaceous times.
