Similar fossils found on different continents helped geologists determine how the continents used to be connected. Mountain belts marked the boundaries of moving plates, which showed in which direction the different continents drifted. Extrapolating from this information, scientists had a rough idea of how the continents were arranged eons ago.

In 1912, a German astronomer named Alfred Wegener proposed that the continents around the Indian Ocean were physically joined and moved apart. This theory explained fossil connection and the existence of glacial deposits. Fossils also found in different continents helped scientists and geologists determine the connection between continents. Mountain belts marked the boundaries of moving plates, which showed in which direction the different continents drifted. Fossils and mountain belts were helpful in deciding where to move the continents since the geologists could see how they were placed together.
