A group of researchers in the Amazon region of Brazil has discovered a massive cave that is more than 2,000 years old.

The discovery is part of a growing body of evidence suggesting the ancient civilization in the area was in fact a nomadic people, but it has raised new questions about how the ancient culture could have developed from the ground up, according to NBC News.

The cave, located in the village of Barranquilla, is just a few feet deep and is located deep in the forest.

But the team had no idea it was such a treasure trove until they dug in and found a tunnel that leads into the cave.

Researchers say it could be a burial chamber, possibly used to store ancient knowledge.

But that’s not the only surprise.

It’s a mystery because it is a very old and poorly understood archaeological site, and the discovery suggests that ancient people were likely moving about on the landscape of this region in a relatively short time frame, said co-author Luis Carlos Gomes de Andrade, a professor at the University of Rio de Janeiro.

He told NBC News the discovery was a “major breakthrough” in ancient history.

The team of researchers says the cave contains an unusual burial chamber that is made of wood.

Researchers are still analyzing the remains, and they believe that the cave may have been used for religious purposes.

They have not yet confirmed that this is the burial chamber.

But they have determined that the chamber is older than the site of the cave and is probably more than 3,000 to 5,000 year old, Gomes told NBC.

This discovery is a big deal because it means that we have discovered a cave that was once used for a very important religious ritual, he said.

Researchers have been excavating a large site in the region for more than a decade and have discovered hundreds of small and large burials and other artifacts.

They are studying the remains to try to find out how the culture developed from a nomad society and how that transition may have affected the people of the area.

But a large cave has not been found before.

The first time scientists were excavating the area, in the 1990s, they discovered the remains of a cave complex that was a very long time ago, Goses said.

So, it was a surprise to find something so far back in time.

It was very exciting to find this large cave in a place that was so remote.

He said the research team is currently working to learn more about the ancient people and their society.

Gomes also said he was “absolutely thrilled” to find the cave because it may be the only cave that has ever been found in the whole Amazon region.

He believes that this cave was used to bury a huge number of artifacts, which may have served as a burial location for a number of important people.

Gome and colleagues say they are now working to understand the culture of the people who lived in the time before the cave was built, and whether that is similar to the culture we see in the archaeological record.

And they hope that the discovery will help us understand the evolution of the ancient world.

Goma said he hopes that more ancient sites like the one in the cave will be discovered and studied.

“The knowledge we have now is very important for us as scientists to have, because it will allow us to better understand the history of our ancient world,” he said in a statement.

Gomas said that other sites in the same region could be studied, too, so the cave could be one of many places that researchers can study the ancient inhabitants of this area.

The excavation is one of a number that scientists have been doing in the areas surrounding the village.

Earlier this year, scientists found a small cave in northern Brazil that was also buried.

The site, which has been called “Cave of the Fallen” by local people, is also thought to be the site where the ancient Mayan civilization disappeared.

Researchers were surprised to find so much artifacts there, but there was also a large quantity of clay and other earth that was deposited.
