Believed that continents such as africa and south america were once joined. Drew a map based on this concept, and although the fit was not perfect, it did provide enough evidence for pangea: similar fossils and rock types were found on multiple continents. Similar fossils could be found on different continents, therefore must had been connected at some point: evidence for different latitude positions in the past for a given reason. Several mountain belts terminate at one coastline and reappear on a continent across an ocean, suggesting they were once part of one continuous chain.
