Relics from largest underwater cave

Relics from largest underwater cave


  • Archaeologists who have been exploring the world’s largest underwater cave presented their findings
  • Project sponsored by Mexico’s National Institute of Anthropology and History (INAH).


  • Two large networks of underwater caves in Mexico’s Yucatan peninsula, the Sac Actun and Dos Ojos networks, are in fact connected, forming the largest such structure on Earth.
  • Fossils of giant sloths and an elaborate shrine of the Mayan god of commerce also discovered
  • Researchers believe that the water level in the caves has fluctuated over time, and that they were a source of water in times of severe drought — sometimes a perilous one.
  • Some of the animals and humans who ventured inside never made it out alive.
  • Then there are the artefacts left inside by humans: burnt human bones, ceramics, wall etchings and more.


The remains are a treasure trove for scientists, enabling them to piece together bits of the cave’s history dating all the way back to the Pleistocene epoch (2.6 million to 11,700 years ago).
