Beijing, October 15, 2017 : Archaeologists have excavated 800-year-old city walls and gates in China’s Chongqing. More than 300 relics and evidence that a complete defense system existed at the time have been unearthed.
A township in Fengjie county’s Baidi was once a very important military fortress. The archaeological dig launched at the site in February discovered the ruins, Xinhua news agency reported.
In the first six months, 20 sections of the city wall, gates, defence towers and armouries were found.
These were confirmed as dating to the period between 1127 and 1912 when the Southern Song Dynasty and later the Qing Dynasty was in power.
Over 300 relics, mainly iron weapons and some ceramic, copper and stone artifacts, have also been unearthed, Chongqing Cultural Heritage Research Institute said.
The project also identified the layout of Baidi. Other sites discovered outside the town have shown that a complete defence system existed at that time, archaeologists said.
The Cultural Heritage Research Institute of Chongqing and the Cultural Relic Management Office of Fengjie jointly conducted the excavations. (IANS)
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)
De Anda is also director of the Gran Acuifero Maya (GAM), a project dedicated to the study and preservation of the subterranean waters of the Yucatan peninsula.
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.”
The Pleistocene geological epoch, the most recent Ice Age, began 2.6 million years ago and ended around 11,700 years ago. VOA
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
