Deep in the turquoise waters off Mexico’s Caribbean coast, shattered skulls and scattered bone fragments have emerged from the darkness — the remains of humans who lived at least 8,000 years ago.
This discovery adds another extraordinary chapter to the story of America’s earliest inhabitants.
The prehistoric skeleton was found in an underwater cave system located between the tourist destinations of Tulum and Playa del Carmen. Found about 656 feet into the cave, 26 feet below the surface, the remains were recovered in late 2025 and are currently being analyzed.
Professional cave diver Peter Broser At first a shattered skull and bone fragments were found before contacting a cave-diving archaeologist. Octavio del Rio to investigate.
Del Rio, who collaborates with the National Institute of Anthropology and History, has been exploring the area. cenotes — Freshwater sinkhole caves formed by collapsing limestone pits — for three decades.
“You can even scream underwater,” Del Rio said The Associated Press Seeing skeletons up close for the first time.
This is the 11th skeleton found in these caves in the last three decades.
Human remains found in cenotes in Mexico
The skeleton was found partially covered in sediment, and its position in the sediment pile suggests deliberate placement – possibly as part of a ritual burial practice.
Its distance from the cave entrance rules out placement by later Paleoamericans, pointing instead to people who knew these caves well.
The cave system was flooded at the end of the last ice age – the end of the Pleistocene era – about 8,000 years ago, due to sea level rise from melting ice.
That timeline gives researchers a minimum age for the skeleton, though it could be much older. Further studies are still needed, including dating, photographic studies and collections.
When this person was alive, the Yucatan Peninsula It was a semi-arid savanna with no rivers or lakes. There was a lack of water and shade. Some researchers believe that ancient people sought relief from the heat in caves, which were fed by fresh groundwater.
The ancient Mayans later believed that cenotes were sacred Portals to the UnderworldWhere gods and spirits resided.
Oldest human remains in America
What makes this cave system extraordinary isn’t just the new discovery – it’s the astonishing collection of ancient remains that have already been recovered there.
Some of the earliest skeletons found in the same area are about 13,000 years old, making them the oldest human remains in North America.
In fact, the oldest known skeleton found in cenotes is “Eva of Naharon(Eve of Naharon), estimated to be 13,721 years old – currently the oldest known human fossil in the Americas.
That number puts human presence in the Yucatan thousands of years before the caves flooded at the end of the last ice age.
DNA data supports the theory that early inhabitants arrived from Asia via a land bridge across what is now the Bering Strait, although some indications also suggest a South American route.
Each new skeleton provides another potential data point to disentangle these competing migration stories.

Future discoveries are in imminent danger
As innovations grow, so do threats.

Steel support columns operating in the caves have caused rust and iron contamination in the water, and fallen stalactites are making some cenotes unsafe to explore.

“These ecosystems are very, very fragile,” Geologist Emiliano Monroy-Rios Northwestern University told The Associated Press in 2024. “They are building on the ground. […] Filled with caves and caverns of various shapes and depths.
Mexican authorities are now working to designate the entire area as a national protected area. Mexico’s environment ministry confirmed to AP that it aims to achieve that designation in 2026.
For now, archaeologists are under pressure to find and document as much as possible before mass tourism further impacts the region.
Only expert divers with special equipment can access the caves today—but what they’ve found there is reshaping our understanding of who the first Americans really were and how they lived thousands of years before civilization as we know it took shape.
