An extraordinary discovery has been made under the waters of the Madura Strait, between the islands of Java and Madura in Indonesia, where scientists have found the fossil remains of Homo erectus, one of the earliest ancestors of man.
This discovery could fundamentally change the story of the origins of humanity and provide direct evidence for the existence of the lost world known as Sundaland – a vast tropical landmass that once connected Southeast Asia.

The fossils were first discovered in 2011 by marine miners extracting sand from the sea, but only recently have their age and type been determined by scientists.
Among them were two skull fragments of Homo erectus, which were compared with known fossils from Java and confirmed as belonging to this species.
Along with the human remains, over 6,000 animal fossils from 36 different species were found, including deer, buffalo, elephants, and giant lizards like the Komodo Dragon.
Some of the bones showed clear cut marks, proving that early humans used advanced hunting and meat processing techniques.

The discovery occurred in what was once a major river system, called the ancient Solo River Valley, which ran through the now-sunken Sundaland Plain. Sediment analyses showed that the area had been a thriving environment with rivers and open grasslands during the Middle Pleistocene epoch, around 162,000 to 119,000 years ago.
To determine the age of the layers where the fossils were found, the researchers used a method called Optically Stimulated Luminescence (OSL), analyzing quartz grains that dated back to the period when they were last exposed to sunlight.
The discovery of these fossils significantly expands the distribution map of Homo erectus.

This represents an important moment in human evolution, as Homo erectus was the first species to have a longer body, shorter arms, and a fully upright gait, a major step towards Homo sapiens.
Among the animals discovered was the Stegodon, similar to modern elephants, which reached up to 4 meters in height and weighed over 10 tons. Various deer and other herbivorous animals such as antelopes testify to a savannah-type landscape, which provided abundant food for early humans.
