Continental drift is a highly supported scientific theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics , which studies the movement of the continents as ...
Map of Pangea showing locations of Lystrosaurus remains as yellow disks. Distorted boundaries of modern continents shown as grey lines. (Distributions for lystrosaurs and three other Permian and Triassic fossil groups used as biogeographic evidence for continental drift and certain land bridges.)
Mesosaurus was significant in providing evidence for the theory of continental drift, because its remains were found in southern Africa, Whitehill Formation, and eastern South America (Melo Formation, Uruguay and Irati Formation, Brazil), two widely separated regions.
The second piece of evidence in support of continental drift came during the late 1950s and early 60s from data on the bathymetry of the deep ocean floors and the nature of the oceanic crust such as magnetic properties and, more generally, with the development of marine geology [57] which gave evidence for the association of seafloor spreading ...
The concept that the continents once formed a contiguous land mass was hypothesised, with corroborating evidence, by Alfred Wegener, the originator of the scientific theory of continental drift, in three 1912 academic journal articles written in German titled Die Entstehung der Kontinente (The Origin of Continents).

He presented his continental drift hypothesis on 6 January 1912. He analysed both sides of the Atlantic Ocean for rock type, geological structures and fossils. He noticed that there was a significant similarity between matching sides of the continents, especially in fossil plants. Fossil patterns across continents
Distribution of four Permian and Triassic fossil groups used as biogeographic evidence for continental drift, land bridging.. The continent of Gondwana was named by the Austrian scientist Eduard Suess, after the region in central India of the same name, which is derived from Sanskrit for "forest of the Gonds". [6]
Distribution of four Permian and Triassic fossil groups used as biogeographic evidence for continental drift, and land bridging. Location of Cynognathus remains shown by red diamonds. Fossils have been found in the Karoo, the Puesto Viejo Formation, Fremouw Formation, in South Africa/Lesotho, Argentina and Antarctica.
