Map Sundaland: A Fascinating Journey through Earth’s History

Key Takeaways

  • Sundaland was a vast region present during the Pleistocene epoch.
  • It encompassed the modern-day islands of Borneo, Sumatra, Java, and the Malay Peninsula.
  • Sundaland played a crucial role in shaping the biodiversity and geological history of Southeast Asia.
  • Exploring the map Sundaland provides insights into the ancient landmass and its evolution.

History

Sundaland, also known as the Sunda Shelf, refers to a large landmass that existed during the Pleistocene epoch between 2.6 million and 11,700 years ago. It extended across what is now Borneo, Sumatra, Java, and the Malay Peninsula. The region was named after the Sunda Plate, which remains as the stable continental crust beneath these areas.

During the Pleistocene epoch, the global sea level fluctuated greatly due to ice ages. This resulted in the exposure of vast areas of shallow seabed, creating land bridges that connected the islands of Southeast Asia. Sundaland acted as a biogeographical region, facilitating the migration of various animal and plant species between present-day islands.

The landmass of Sundaland housed a diverse range of ecosystems, including rainforests, swamps, savannas, and rivers. It was home to a rich array of flora and fauna, including ancient humans such as Homo erectus and Homo floresiensis. The region played a crucial role in human migration and evolution, and archaeological discoveries continue to shed light on our ancient ancestors.

1. Biodiversity Hotspot

Sundaland was a biodiversity hotspot, with countless species evolving and adapting to its diverse environments. Researchers estimate that the region was inhabited by over 10,000 plant species and supported a wide range of animal life, including tigers, elephants, orangutans, and rhinoceroses.

2. Megafauna Presence

The fossil records found in Sundaland reveal the presence of ancient megafauna that roamed the land during the Pleistocene epoch. These included species like Stegodon, a distant relative of elephants, and giant crocodiles called Crocodylus thorbjarnarsoni.

3. Tectonic Activity

The geological history of Sundaland is shaped by tectonic activity. The region is situated at the junction of several tectonic plates, making it prone to earthquakes and volcanic eruptions. The volcanoes in Indonesia, such as Krakatoa and Mount Tambora, are remnants of this tectonic activity.

4. Role in Human Evolution

Sundaland played a significant role in the migration and evolution of early humans. It is believed that Homo erectus used the land bridges to disperse from Africa and eventually reach Southeast Asia. The discovery of the “Hobbit” species (Homo floresiensis) on the island of Flores provides evidence of ancient human diversity in the region.

5. Submerged Ruins

Due to rising sea levels, many ancient settlements and archaeological sites in Sundaland now lie underwater. These submerged relics provide valuable insights into past civilizations and their interaction with the environment.
