In the 1920s, scientists who rejected his hypothesis had to provide other explanations for the observed correlation in fossils, stratigraphy, and glaciation, especially between South America, Africa, and India. European geologists had formerly relied on rising and sinking continents to account for these similarities, and indeed Wegener obtained his concept of Gondwanaland from Suess.
