In a kinder world, archaeologists would study only formal cemeteries, carefully planned and undisturbed. No landslides would have scattered the remains. No passersby would have taken them home as souvenirs, or stacked them into cairns, or made off with the best of the artifacts. The lake, which is formally known as Roopkund, is miles above sea level in the Himalayas and sits along the route of the Nanda Devi Raj Jat, a famous festival and pilgrimage. Bones are scattered throughout the site: Not a single skeleton found so far is intact. Since a forest ranger stumbled across the ghostly scene during World War II, explanations for why hundreds of people died there have abounded. These unfortunates were invading Japanese soldiers; they were an Indian army returning from war; they were a king and his party of dancers, struck down by a righteous deity. A few years ago, a group of archaeologists suggested , after inspecting the bones and dating the carbon within them, that the dead were travelers caught in a lethal hailstorm around the ninth century. In a new study published today in Nature Communications , an international team of more than two dozen archaeologists, geneticists, and other specialists dated and analyzed the DNA from the bones of 37 individuals found at Roopkund.
A simple approach to dating bones
A skeleton named Little Foot is among the oldest hominid skeletons ever dated at 3. Little Foot is a rare, nearly complete skeleton of Australopithecus first discovered 21 years ago in a cave at Sterkfontein, in central South Africa. The new date places Little Foot as an older relative of Lucy, a famous Australopithecus skeleton dated at 3. It is thought that Australopithecus is an evolutionary ancestor to humans that lived between 2 million and 4 million years ago.
Stone tools found at a different level of the Sterkfontein cave also were dated at 2. A team of scientists from Purdue University; the University of the Witwatersrand, in South Africa; the University of New Brunswick, in Canada; and the University of Toulouse, in France, performed the research, which will be featured in the journal Nature.

Even more than Germany’s Neander Valley, which gave Neanderthals their name, Shanidar Cave evokes the lost world of our closest evolutionary kin, when they were active humans, with their own traditions and social bonds, rather than scattered bones and artifacts. Excavations began in the middle of the 20th century at the site, located about 60 miles northeast of the city of Mosul in the Kurdish region of Iraq. The digs turned up 10 skeletons, including the remains of two infants.
Dating methods were considerably less precise at the time, but the range established for the remains was from roughly 50, years ago to a mere 35,, representing the twilight of their kind. If I seem to be waxing poetic about Shanidar, blame Jean Auel. Like many ’80s kids, I read The Clan of the Cave Bear and other titles from her Earth’s Children series, which was inspired by finds at the cave.
Dramatic embellishments aside, the books had many of us skipping the mall and instead hitting the library to learn more about Neanderthals.

Radiocarbon dating and analysis
A critical aspect of tracing migration events is dating them. Inspired by the Geographic Population Structure model that can track mutations in DNA that are associated with geography, researchers have developed a new analytic method, the Time Population Structure TPS , that uses mutations to predict time in order to date the ancient DNA. At this point, in its embryonic state, TPS has already shown that its results are very similar to those obtained with traditional radiocarbon dating.
We found that the average difference between our age predictions on samples that existed up to 45, years ago, and those given by radiocarbon dating, was years.

Osteological evidence comes from submerged caves and sinkholes cenotes near Tulum in the Mexican state of Quintana Roo. Here we report on a new skeleton discovered by us in the Chan Hol underwater cave, dating to a minimum age of 9. This is the third Paleoindian human skeleton with mesocephalic cranial characteristics documented by us in the cave, of which a male individual named Chan Hol 2 described recently is one of the oldest human skeletons found on the American continent.
The new discovery emphasizes the importance of the Chan Hol cave and other systems in the Tulum area for understanding the early peopling of the Americas. The new individual, here named Chan Hol 3, is a woman of about 30 years of age with three cranial traumas. There is also evidence for a possible trepanomal bacterial disease that caused severe alteration of the posterior parietal and occipital bones of the cranium. This is the first time that the presence of such disease is reported in a Paleoindian skeleton in the Americas.
This supports the presence of two morphologically different Paleoindian populations for Mexico, coexisting in different geographical areas during the Late Pleistocene-Early Holocene.

Richard III dig: DNA confirms bones are king’s
E ach year, more than 1 million people visit Xplor , a subaquatic theme park located a few kilometers south of Playa del Carmen, a popular tourist town on the Caribbean coast of southeast Mexico. Visitors swim in submerged caves, tear through the jungle in all-terrain vehicles, and zip line on hammocks—all of them likely oblivious to the human remains locked away in a laboratory on site and the scientists who are scrutinizing those remains for clues to the people and animals that lived in this very region around 10, years ago.
In one room, for example, fossils go through a dehumidification process to prevent any fungal colonization, not uncommon in such a tropical climate. The lab mostly houses 3-D printed replicas of skeletal remains found in the submerged caves in the state of Quintana Roo. Recent work has focused on describing the morphological diversity of those individuals. Their results, published January 29 in PLOS ONE , indicate that each ancient skull shared features with a different modern population, suggesting a high degree of morphological diversity among these individuals, and, potentially, among early North American settlers.
Forensic anthropologist Ann Ross describes the techniques she uses to determine the age of human skeletons.
In her current role as head of the Human Identification and Forensic Analysis Laboratory at North Carolina State University in Raleigh, she does much the same for the people of her state. The lab has enough tables for four skeletons.
Radiocarbon Dating Helps Provide Answers to Secrets of Skeleton Lake
We’re open! Book your free ticket in advance. The Broken Hill 1 Kabwe skull became the first historically significant human fossil found in Africa when it was discovered in Zambia in Almost one hundred years later and the remains of this ancient human are continuing to shed light on how humans evolved, after a new analysis of the fossil has shown it to be much younger than previously thought. When the Broken Hill skull was first discovered in what is now Kabwe, Zambia, it was quickly realised to have belonged not to a modern human, but an ancient one.
While initially it was named Homo rhodesiensis , it has since been classified as one of the best preserved fossils of another ancient human species called Homo heidelbergensis.
Little Foot is a big deal. Not only is this rare and wonderfully preserved skeleton the most complete australopithecine — a putative evolutionary ancestor.
Skip to content. Skip to navigation. How old are the bones found under the Greyfriars church? C and C are stable but C decays at a known rate, with a half-life of 5, years. The small pieces of bone were combusted to produce carbon dioxide which was then put through a mass spectrometer. Testing two pieces each at two different facilities should provide consistent results — and indeed it did.
However, all was not lost. The proportion of C in the atmosphere, and hence in living things, is not constant but varies over the centuries, and it also varies between the atmosphere and the oceans. Radiocarbon dating of marine organisms can be out by up to several hundred years, and this effect can occur to a lesser degree in terrestrial life where sea-food forms part of the diet. The mass spectrometry of the Greyfriars bone samples reveals that the individual in question had a high-protein diet including a significant proportion of seafood.
This would seem reasonable for a medieval nobleman, and certainly for a member of the royal family. This does not, of course, prove that the bones are those of Richard III. And it also tells us something about what he had for supper.
