Humans reached Australia 65,000 Years Ago, About 15,000 Years Earlier than Previously Thought: Study

Researchers were also able to retrieve several tools in three different layers of sediment, including an ax, the oldest-known grindstone in Australia, and some early paints showing the oldest-known use of minerals

Canberra, July 23, 2017: The first settlers of Australia reached the continent 65,000 years ago, about 15,000 years earlier than experts previously thought, a new archaeological study revealed on Thursday.

The archaeologists made the conclusion following an excavation at the Madjedbebe rock shelter near Kakadu National Park in northern Australia, one of the most important archaeological sites in the region known for its early rock paintings, reports Efe news.

The site was last excavated nearly 30 years ago by a group of archaeologists, who suggested that the site was between 50,000 and 60,000 years old, considered to be one of the first human settlements in Australia. Between 2012 and 2015, archaeologists returned to the site to conduct new excavations.

The latest research included new techniques of analysis, like luminescence dating – which can determine when single grains of sand were last exposed to sunlight – allowing the research team to verify the age of the sediment surrounding the objects.

Researchers were also able to retrieve several tools in three different layers of sediment, including an ax, the oldest-known grindstone in Australia, and some early paints showing the oldest-known use of minerals.

“We found there was an incredible richness of evidence of wonderful human behaviour that we didn’t really have indications of from earlier excavations,” said Chris Clarkson, project leader from the University of Queensland.

Clarkson noted that the findings of his research, published on Thursday by the journal Nature, indicated a solid cultural continuity at the site across thousands of years. The archaeologist added that this discovery could also contribute to a better understanding of humans’ migration from Africa to Southeast Asia. (IANS)

Ancient Human Remains, Ice Age Animal Bones Found in Giant Mexican Cave

  • Archaeologists found ancient human remains in Mexico
  • The remains were found in a flooded cave in Mexico
  • Archaeologists also found bones of ancient animals

Archaeologists exploring the world’s biggest flooded cave in Mexico have discovered ancient human remains at least 9,000 years old and the bones of animals who roamed the Earth during the last Ice Age.

A group of divers recently connected two underwater caverns in eastern Mexico to reveal what is believed to be the biggest flooded cave on the planet, a discovery that could help shed new light on the ancient Maya civilization.

The Yucatan peninsula is studded with monumental relics of the Maya people, whose cities drew upon an extensive network of sinkholes linked to subterranean waters known as cenotes.

Researchers say they found 248 cenotes at the 347-km (216-mile) cave system known as Sac Actun, near the beach resort of Tulum. Of the 200 archaeological sites, they have discovered there, around 140 are Mayan.

Some cenotes acquired particular religious significance to the Maya, whose descendants continue to inhabit the region.

Apart from human remains, they also found bones of giant sloths, ancient elephants and extinct bears from the Pleistocene period, Mexico’s Culture Ministry said in a statement.

The cave’s discovery has rocked the archaeological world.

“I think it’s overwhelming. Without a doubt it’s the most important underwater archaeological site in the world,” said Guillermo de Anda, a researcher at Mexico’s National Anthropology and History Institute (INAH)

According to the INAH, water levels rose 100 meters at the end of the Ice Age, flooding the cave system and leading to “ideal conditions for the preservation of the remains of extinct megafauna from the Pleistocene.”
