The research looks at the vast supercontinent that was known as Sahul, a landmass that was exposed about 70,000 years ago, during the Pleistocene epoch, when Earth was in the midst of the last ice ...
Sahul is the name given to the single Pleistocene-era continent which connected Australia with New Guinea and Tasmania. At the time, the sea level was as much as 150 meters (490 feet) lower than it is today; rising sea levels created the separate landmasses we recognize. When Sahul was a single continent, many of the islands of Indonesia were ...
A map of Sahul, the supercontinent that included Australia, Papua New Guinea, and Tasmania. Illustration: Salles et al/Nature Communications . As sea levels rose at the end of the Pleistocene, the landscape took the form we now know. How the first humans reached Sahul is still a mystery, and the paths they took to spread across it are also lost ...
Sahul can be termed as a supercontinent, stood exposed on the Earth's surface when humans were in the middle of what can be termed as the last ice age. Since the ice age led to glaciation of water levels on the planet, it ended up exposing parts of land like Sahul which connected to currently known Australia to Papua New Guinea in the north and ...
French and Australian scientists have modelled the evolving landscape of the ancient supercontinent Sahul to work out how quickly humans were able to populate the landmass that would eventually ...
Scientists are rewriting what we thought we knew about early human history and a prehistoric supercontinent called ‘Sahul’ has an outsize role in the story. Existing in the Pleistocene Epoch, from around 2.6 million to around twelve thousand years ago, it consisted of mainland Australia, attached to Tasmania, and to many of the islands we ...
A team of archaeologists and earth scientists have recently unveiled insights into the ancient terrains of Sahul, the landmass that during the Ice Age included Australia and New Guinea. Their research, which was published in Quaternary Science Reviews, reveals intriguing details about a lesser-known period in human history.
About Sahul: It can be termed as a supercontinent which stood exposed on the Earth's surface when humans were in the middle of what can be termed as the last ice age.; Since the ice age led to glaciation of water levels on the planet, it ended up exposing parts of land like Sahul which connected to currently known Australia to Papua New Guinea in the north and Tasmania in the south,
Our latest research advances our knowledge about the most likely routes those early Australians travelled as they peopled this giant continent.. We are beginning to get a picture not only of where those first people landed in Sahul, but how they moved throughout the continent.. Navigating the landscape. Modelling human movement requires understanding how people navigate new terrain.
GKToday Notes: Sahul. Sahul is a prehistoric supercontinent. It comprised present-day Australia, New Guinea, and Tasmania. Sahul existed during the ice ages. Sea levels were much lower, exposing the land bridges. It separated into its current landmasses roughly 10,000 years ago. Sahul was home to a diverse range of megafauna.
This finding sheds new light on human history and migration patterns, revealing a supercontinent that was exposed during the last ice age. What is Sahul? Sahul was a supercontinent that existed during the last ice age. During this period, extensive glaciation caused sea levels to drop, exposing landmasses that are now submerged.
The researchers combined the data from two previously published studies, one that modeled patterns of population movement and growth via a grid-based system and one that charted the probable 'superhighways' of exploration based on landscape features.. Routes and population spread in Sahul. (Bradshaw et al., Quaternary Science Reviews, 2023) As well as extending the prediction for the time it ...
During the late Pleistocene epoch, sea levels were so low that Australia was connected to its northern neighbors, New Guinea and Indonesia, in a supercontinent known as Sahul. But then, at the end of the last ice age, around 10,000 years ago, vast swathes of land were flooded as ice sheets melted.

Extreme environmental change was the most likely cause of extinction of megafauna in Sahul, the supercontinent formed by Australia and New Guinea during periods of low sea level, according to an analysis of megafauna fossils from the site of South Walker Creek near the township of Nebo, Australia. ... Extinction of eastern Sahul megafauna ...
The supercontinent of Australia and New Guinea that was connected during much of the late Quaternary—known as the continent of Sahul (Fig. 1)—provides a case study to test and examine human ...
This process split the supercontinent of Sahul into New Guinea and Australia, and cut Tasmania off from the mainland. ... We found low sea levels exposed a vast archipelago of islands on the Northwest Shelf of Sahul, extending 500km towards the Indonesian island of Timor. The archipelago appeared between 70,000 and 61,000 years ago, and ...
Sahul, a supercontinent, connected present-day Australia, Papua New Guinea, and Tasmania. This land bridge facilitated human movement from Asia to Australia around 70,000 years ago. Ice ages are geologic periods featuring extensive ice cover, lasting millions of years, reshaping continents. The earliest known ice age dates back over 570 million ...
