Lost lands are the land mass that supposedly existed during prehistory but have now having disappeared as a result of catastrophic geological phenomena or slowly rising sea levels since the end of the last Ice Age. In some cases, these land masses leave behind few traces, whereas some of them are purely legends.
The classification of lost lands can be further divided into lost continents, lost islands, or other lost regions. For example, Atlantis can be described as either a “lost island” or a “lost continent”.
