Geologists Suzanna van de Lagemaat and Douwe van Hinsbergen have discovered remnants of an ancient tectonic plate named "Pontus" in Borneo.

This discovery, dating back 120 million years, reveals a previously unknown part of Earth's history. The Pontus plate existed before the supercontinent Pangaea broke apart, and its size is estimated to have been about one-fourth the size of the Pacific Ocean.

The team's research in Borneo, focusing on the Junction region, offers new insights into the movement of tectonic plates and the formation of continents over millions of years.
