What is the evidence for continental drift?

The Continental Drift theory proposed by Alfred Wegener suggested that the continents were not always in the position that they are in today. The main piece of evidence is the jigsaw fit of the continents such as that seen in the shapes of South America and Western Africa. There are also glacial deposits in continents that could not have been made at their current latitude such as the tropical rainforests of Brazil, showing that they have moved into the position that they are now in. Fossils of the ancient reptile, the Mesosaurous, are found in South America and South Africa which are now separated by vast ocean that the reptile could not have swam or flown across. There is also geological evidence for continental drift, as mountain belts across America, Britain and Norway have similar aged rocks suggesting that they were once joined. Palaeomagnetism of fossils is another piece of evidence, as minerals within rocks, such as iron, align with the magnetic field of the earth as they form, and the changing magnetism within the rocks show that the continents do move.
