MEXICO CITY (AP) — A prehistoric human skeleton has been found in a cave system that was flooded at the end of the last ice age 8,000 years ago, according to a cave-diving archaeologist on Mexico’s Caribbean coast.
Archaeologist Octavio del Rio said he and fellow diver Peter Broger saw the shattered skull and skeleton partly covered by sediment in a cave near where the Mexican government plans to build a high-speed tourist train through the jungle.
Given the distance from the cave entrance, the skeleton couldn’t have been reached without modern diving equipment, so it must be over 8,000 years old, Del Rio said, referring to the era when rising sea levels flooded the caves.
“There it is. We don’t know if the body was deposited there or if that was where this person died,” said Del Rio. He said that the skeleton was located about 8 meters (26 feet) underwater, about a half-kilometer (one third of a mile) into the cave system.

This photo shows fragments of a prehistoric human skeleton partly covered by sediment in an underwater cave in Tulum, Mexico. The cave system was flooded at the end of the last ice age 8,000 years ago, according to archaeologist and cave diver Octavio del Rio, and is located near where the government plans to build a high-speed tourist train through the jungle.
Some of the oldest human remains in North America have been discovered in the sinkhole caves known as “cenotes” on the country’s Caribbean coast, and experts say some of those caves are threatened by the Mexican government’s Maya Train tourism project.
Del Rio, who has worked with the National Institute of Anthropology and History on projects in the past, said he had notified the institute of the discovery. The institute did not immediately respond to questions about whether it intended to explore the site.
But Del Rio said Tuesday that institute archaeologist Carmen Rojas told him that the site was registered and would be investigated by the institute’s Quintana Roo state branch Holocene Archaeology Project.
He stressed that the cave — whose location he did not reveal because of a fear the site could be looted or disturbed — was near where the government has cut down a swath of jungle to lay train tracks, and could be collapsed, contaminated or closed off by the building project and subsequent development.
“There is a lot more study that has to be done in order to correctly interpret” the find, Del Rio said.
Del Rio has been exploring the region for three decades, and in 2002 he participated in the discovery and cataloguing of remains known as The Woman of Naharon, who died around the same time, or perhaps earlier, than Naia — the nearly complete skeleton of a young woman who died around 13,000 years ago. It was discovered in a nearby cave system in 2007.

President Andrés Manuel López Obrador is racing to finish his Maya Train project in the remaining two years of his term over the objections of environmentalists, cave divers and archaeologists. They say his haste will allow little time to study the ancient remains.
Activists say the heavy, high-speed rail project will fragment the coastal jungle and will run often above the fragile limestone caves, which — because they’re flooded, twisty and often incredibly narrow — can take decades to explore.
Caves along part of the coast already have been damaged by construction above them, with cement pilings used to support the weight above.
The 950-mile (1,500-kilometer) Maya Train line is meant to run in a rough loop around the Yucatan Peninsula, connecting beach resorts and archaeological sites.
The most controversial stretch cuts a more than 68-mile (110-kilometer) swath through the jungle between the resorts of Cancun and Tulum.
Del Rio said the route through the jungle should be abandoned and the train should be built over the already impacted coastal highway between Cancun and Tulum, as was originally planned.
López Obrador abandoned the highway route after hotel owners voiced objections, and cost and traffic interruptions became a concern.
“What we want is for them to change to route at this spot, because of the archaeological finds that have been made there, and their importance,” said Del Rio. “They should take the train away from there and put it where they said they were going to build before, on the highway … an area that has already been affected, devastated.”

In 2018, Donald Blakeslee, an anthropologist and archaeology professor at Wichita State University, located what he believes are the remains of the lost city of Etzanoa underneath Arkansas City, Kansas. He told the LA Times he suspects the city was home to up to 20,000 people for almost 200 years between 1450 and 1700. This urban hub would upend the traditional belief that Midwestern tribes were scattered nomads. This lost city in Kansas isn't the first time old remains have filled in gaps in American history.

While it is now the name of a popular language learning software, the original Rosetta Stone was a stone slab found in 1799 that proved to be the key to deciphering Egyptian hieroglyphics. The stone was inscribed with three versions of a decree issued 196 B.C.: one in hieroglyphic script, one in Egyptian Demotic script and one in Ancient Greek. It allowed researchers translate hieroglyphics for the first time to understand ancient Egyptian writings and culture. (Dreamstime/TNS)

Older than both Stonehenge and the Egyptian pyramids, the prehistoric monument of Newgrange in Ireland was built around 3200 B.C. Since 1890, it has been conserved and has been the site of archaeological excavations that revealed its function and how it had been built. The site provides insight into ancient art, technology and religion, including the importance of the winter solstice. On that day each year, a small opening calibrated to the location of the sun allows light to stream inside the central chamber. (Dreamstime/TNS)

Easter Island is one of the most remote islands in the world, and its almost 900 monumental statues, called moai, made by the Rapa Nui people, have captivated the imagination of outsiders. They average 13 feet tall and weigh 14 tons. Though it's generally accepted they were built to honor ancestors and former chiefs, the real mystery was how an isolated, small and seemingly primitive people moved these massive blocks miles from a quarry to their locations across the island. Studying the island revealed things about ancient Polynesian culture and society as well as the ecological rise and collapse of the island's ecosystem. (Jane Wooldridge/Miami Herald/MCT)

Chinese farmers digging a well in 1974 struck one of the most iconic and important archaeological discoveries in the world. The Terracotta Army is a collection of thousands of soldier sculptures, along with horses, weapons and chariots, buried with Qin Shi Huang, the first Emperor of China, to protect him in the afterlife. Other figures found in the tomb include musicians, dancers and acrobats, all with different faces and expressions. According to Smithsonian magazine, the thousands of figures and items in the underground pits are an imitation of the real organization within the Qin dynasty. The army's deterioration also points to the collapse of that dynasty not long after Qin's death. (Keri Wiginton/Chicago Tribune/MCT)

Like its neighbor Pompeii, the ancient Roman city of Herculaneum was also destroyed by Mount Vesuvius in 79 A.D. When the city was re-discovered in the 1700s, scientists found a buried library filled with hundreds of preserved papyrus scrolls. Unfortunately, the scrolls were so brittle and burnt that they couldn't be unrolled to read their contents. That is until 2015, when researched developed an X-ray that would allow them to digitally unfurl and read the lost texts. So far the library has proven to contain philosophical texts, but the hope it that there are more first-century Latin texts as well as early Christian writings that could provide more insight into the Roman world.

Immortalized in Homer's "Iliad," the ancient city of Troy is both a literary legend and real-life archaeological site located in modern-day Hisarlik, Turkey. Though it was long debated whether or not Troy was purely a work of fiction, both literary and historic descriptions of its location align with the city found at the present-day site, leading some to believe they're one and the same. Regardless, the area, which was first excavated in 1870 and is still being explored today, bears evidence to the evolution of Mediterranean civilization. (Manuel Cohen/Aurimages via ZUMA Press)

Altamira is a Paleolithic cave located in northern Spain that was discovered in 1868. The cave's detailed drawings were dismissed as fake for decades because of their intricacy and vibrancy, but a 1902 study confirmed their authenticity as dating from 35,000 to 11,000 B.C. The paintings depict fauna of the time period, while early tools were found during excavations of the cave. It's a protected UNESCO World Heritage Site, and the organization describes the drawings as "masterpieces of creative genius" and as "humanity’s earliest accomplished art." In 1940, another preserved series of Paleolithic caves was discovered in Lascaux, France. (Dreamstime/TNS)

This area in Bavaria is famous in geology and archaeology because its layer of Jurassic limestone is ideal for preserving fossil specimens of dinosaurs, dragonflies, plants, insects and more from 155 million years ago. Perhaps the most influential discovery made here was a feather and two Archaeopteryx specimens in the 1860s. With its combination of reptile and bird features, the Archaeopteryx proved to be the "missing link" that illustrated Charles Darwin's then-recently published theory of evolution. (Dreamstime/TNS)
