In a groundbreaking discovery, the oldest Homo Sapien bones ever were discovered in an old barite mine named Jebel Irhoud. This mine is located on a desolate mountain in the North African country of Morocco, around 62 miles (100 kilometers) west of the city of Marrakesh. In Mexico City, the remains of Aztec ruins were unearthed and match up with centuries old accounts from the Aztec's Spanish conquers.

The oldest known human bones

Archaeologists uncovered the Homo sapien bones of at least five people at the mine after years of excavations. This is a discovery that has the potential to shake the long-held belief that modern humans originated out of East Africa around 200,000 years ago.

The archaeologists knew that the remains they uncovered were ancient, but were utterly shocked when the dating test results came in. The remains and stones tools that they have uncovered were an estimated 280,000 to 350,000 years old.

The remains that were discovered at the site included limb bones, teeth, a partial skull and a jawbone. They belonged to three adults, a teenager and a child that was around eight-years-old. Besides the bones, archaeologists also discovered sharpened tools made of flint, gazelle bones and lumps of coal likely left over from fires. Prior to this discovery the oldest known human fossil was 195,000 years old and discovered in Ethiopia.

The archaeological team published two papers on this discovery in the scientific journal 'Nature.'

Ancient Aztec ruins unearthed in Mexico City

Ancient Aztec ruins were unearthed in the center of Mexico City, behind a colonial-era Cathedral. The ruins are what remains of the foundation of a giant circular-shaped Aztec temple.

This temple was dedicated to the wind god Ehecatl. There was also a ceremonial ball court found alongside it. The discovery helps to affirm Spanish chronicles of the Aztec capital of Tenochtitlan from over five hundred years ago.

There was also the discovery of 32 detached neck vertebrae in a pile next to the court. They were an offering for the ball game and likely came from those who were sacrificed.

The temple is thought to have been built between 1486-1502 during the rule of Emperor Ahuizotl. The building would have stood out to the Spanish conquistador Hernan Cortes and his men when they conquered the city in 1521 due to its shape and design. Once excavations are finished, a museum will be constructed on the site.
