Edgar Dacque (1878-1945) was a leading German paleontologist and geologist, who studied under Karl Alfred von Zittel in Munich. The focus of his research was the paleontology of invertebrates and the new field of paleogeography. The hypothetical southern continent of Gondwana made sense to him because of the distribution of important groups of both fossil and recent plants and animals. Since the continental drift hypothesis published by Alfred Wegener in 1915 was still little known and did not appear plausible, Dacqué assumed, in accordance with the prevailing land bridge hypothesis, that land masses between Africa, India and Australia collapsed in the Mesozoic. Many of his ideas are found in his book “Grundlagen und Methoden der Palaogeographie”.
