Discovery of the Lost Continent of Argoland

November 9, 2023

During the dinosaur era, Earth was home to supercontinents—massive landmasses comprising at least 75% of the Earth’s land. Pangea, Gondwana, and Pannotia are the most recognized recent supercontinents. Earlier supercontinents included Nuna (Columbia), Rodinia, and Ur.

Argoland: The Vanished Supercontinent

Argoland was a colossal continent that existed alongside northeastern Australia 155 million years ago.
This landmass, stretching 3,000 miles long, has been a long-standing geological mystery.

Evidence of Existence

Scientists deduced the existence of Argoland from the Argo Abyssal Plain, a vast basin beneath the ocean.
Remnants of Argoland are believed to be buried under parts of Southwest Asia, including Indonesia and Myanmar.

Solving the Mystery

Using paleomagnetic observations, researchers have traced the fragmentation of Argoland.
The continent began breaking apart around 300 million years ago, during Gondwana’s era.

Research Findings

The study identifies fragments of Argoland in regions like Southwest Borneo and West Burma.
Unlike other continents that split into two, Argoland shattered into numerous pieces, making its historical path complex.

Implications of the Discovery

The findings challenge the notion that continents can disappear without a trace.
This research enables more accurate reconstructions of Earth’s geological past, illustrating the dynamic changes of continental structures.
