In the modern world, there remains very few parts of the world that are genuinely undiscovered by civilization.

For thousands of years, humankind spent much of their time exploring the world, and inhabited land on Earth has near-entirely been covered.

Thus, there is a massive clamour online whenever it is revealed that another civilization has been found.

The group of uncontacted people live near the Bolivian border, as per The Guardian, and are called the ‘Massaco people’.

All of the pictures appear to show the group living nude in the rainforest, and are reported to have a population of 2-300 people.

This is double the population from the early 1990s, according to Brazilian National Indigenous Peoples Foundation (Funai).

The group are one of 28 isolated communities in Brazil.

The Guardian report that there are thought to be another 85 reported, but these have not yet been fully confirmed.

Funai veteran Altair Algayer told The Guardian: “On our most recent expeditions and in satellite images, we’ve seen more new tapiris [thatched huts], so I wouldn’t be surprised if there are 300 individuals”.

Algayer took what are believed to be the first ever pictures of the tribe.

The photos, taken in 2019 and 2024, have been published for the first time ever by The Guardian alongside Brazilian newspaper O Globo.

The newspaper said that Algayer is a ‘legend’ among Funai due to his longstanding protection of the Massaco people.

Funai have reportedly found abandoned bow and arrows in Massaco camps, with some exceeding three metres in length.

Algayer said: “How they shoot the arrow, we have no idea. Other Indigenous people also try to understand, laugh and say it’s impossible. Perhaps lying down, they say, but to this day, we have no answer to this mystery”.

The photographs taken by the longstanding member of Funai show the Massaco people picking up tools left for them.

It also shows them planting spikes in the ground, assumedly to ward off unwanted visitors.

The Guardian’s article states that the cameras were placed to ‘better quantify the population without risking contact’.

Analysing the images, Algayer believes he has identified the leader of the group, saying: “The oldest one holding the stick has the spike under his arm. The stick he holds serves as a staff, but it is used more for drilling holes in the ground to place the spikes.

“He has this leadership posture, helps to place the spikes, and tells where to place them.”
