    William Taylor, an assistant professor of anthropology and curator of archaeology in the Museum of Natural History at CU Boulder, says this research shows that the story about people and horses in the Americas is "far more dynamic" than previously thought...Juan Bautista Belardi, a professor of archaeology at the Universidad Nacional de la Patagonia Austral in Argentina and Taylor's research colleague, and his team in Patagonia conducted all the field research at a canyon site called Chorrillo Grande 1 in southern Argentina. They unearthed the remains of an Aónikenk/Tehuelche campsite (people of the Indigenous Tehuelche nation traditionally used horses for...

    In January 2020, Jeff Pigati and Kathleen Springer, both research geologists at the U.S. Geological Survey, went to New Mexico’s Tularosa Basin at White Sands National Park to see about some footprints. These weren’t just any footprints; the fossilized tracks represent the oldest human footprints in North America. What’s more, Tularosa Basin, about 20,000 years ago, was in the midst of what’s known as the Last Glacial Maximum (LGM). During this chilly, final part of the Pleistocene Era, the global sea level was about 400 feet lower and glaciers covered 25 percent of Earth’s land. Their mission was to find...
  • 7,000-year old fish traps excavated in Norwegian mountain lake – a race against time as the water is coming in

    The four fish traps discovered by mountain hiker Reidar Marstein last summer consist of long poles that have been driven into the seabed. They form the pattern of a fence that has guided the fish into a chamber. From there, Stone Age folks could easily use a fishing net to catch the fish they needed.Each chamber consisted of around 40-50 poles, and the archaeologists have found remains that are as much as 80 centimetres long. They are so well preserved that they 'might as well have been cut last year', they write enthusiastically on KHM's Facebook page.In the Norwegian mountains,...
  • Back to the future: The advantage of studying key events in human evolution using a new high resolution radiocarbon method

    Radiocarbon dating is the most widely applied dating method in archaeology, especially in human evolution studies, where it is used to determine the chronology of key events, such as the replacement of Neanderthals by modern humans in Europe. However, the method does not always provide precise and accurate enough ages to understand the important processes of human evolution. Here we review the newest method developments in radiocarbon dating ('Radiocarbon 3.0'), which can lead us to much better chronologies and understanding of the major events in recent human evolution. As an example, we apply these new methods to discuss the dating...

    Indigenous peoples as far north as Wyoming and Idaho may have begun to care for horses by the first half of the 17th Century, according to a new study by researchers from 15 countries and multiple Native American groups.A team of international researchers has dug into archaeological records, DNA evidence and Indigenous oral traditions to paint what might be the most exhaustive history of early horses in North America to date. The group's findings show that these beasts of burden may have spread throughout the American West much faster and earlier than many European accounts have suggested...To tell the stories...

    A 3,000-year-old toddler's shoe from the Bronze Age, dating from between 888 and 781BC, has been discovered in a north Kent riverbed.A comforting fact is since then at least 62 billion people have come and gone on Earth and many have likely also faced the same shoe problem that parents today often scratch their heads about.The rare Bronze Age 15cm leather shoe is thought to be the oldest found in the UK and was found by archaeologist Steve Tomlinson, 51, as he was mudlarking in September.Mr Tomlinson, from Ramsgate, Kent, didn't think much of the find at first but sent...
  • Tree rings could pin down Thera volcano eruption date

    "The longest chronology in the world stretches back 12,000 years. But in the Mediterranean, the problem is that we don't have a full, continuous record going back to the time of Thera," Pearson said. "We have recorded the last 2,000 years very well, but then there's a gap. We have tree rings from earlier periods, but we don't know exactly which dates the rings correspond to. This is what's called a 'floating chronology.'" Filling this gap could help pin down the Thera eruption date and paint a climatic backdrop for the various civilizations that rose and fell during the Bronze...

    The dating of a piece of olive tree found on Thirasia will move the dating of the eruption of Santorini's volcano a few decades later than current estimates, the Ministry of Culture and Sports said on Friday. The wood was found in the area "Kimissi Thirassias", the prehistoric settlement which lies on a hillside of the island once connected to Thira, or Santorini, at least up to the Middle Bronze Age, before the volcano exploded. The settlement is on top of a hill on the southern side of Thirasia, and on the edge of the caldera that existed before the...

    April 28, 2006Cornell study of ancient volcano, seeds and tree rings, suggests rewriting Late Bronze Age Mediterranean history By Alex Kwan Separated in history by 100 years, the seafaring Minoans of Crete and the mercantile Canaanites of northern Egypt and the Levant (a large area of the Middle East) at the eastern end of the Mediterranean were never considered trading partners at the start of the Late Bronze Age. Until now. Trenchmaster Vronwy Hankey and foreman Antonis Zidianakis excavate storage jars from the Minoan settlement Myrtos-Pyrgos. The jars were analyzed in the Cornell study using radiocarbon analyses. Cultural links between...

    An international team of researchers has found evidence that people lived on islands in the Azores archipelago approximately 700 years earlier than prior evidence has shown. In their paper, published in Proceedings of the National Academy of Sciences, the group describes their study of sediment cores taken from lakes on some of the islands in the archipelago.Due to the absence of other evidence, historians have believed that people first arrived in the Azores in 1427, when Portuguese sailor Diogo de Silves landed on Santa Maria Island. Soon thereafter, others from Portugal arrived and made the archipelago their home. In this...

    Machu Picchu, the famous 15th-century Inca site in southern Peru, is up to several decades older than previously thought, according to a new study led by Yale archaeologist Richard Burger.Burger and researchers from several U.S. institutions used accelerator mass spectrometry (AMS) — an advanced form of radiocarbon dating...Historical sources dating from the Spanish invasion of the Inca Empire indicate that Pachacuti seized power in A.D. 1438 and subsequently conquered the lower Urubamba Valley where Machu Picchu is located. Based on those records, scholars have estimated that the site was built after A.D. 1440, and perhaps as late as A.D. 1450,...

    In Rome lies the Santi Apostoli church, cared for by Franciscan brothers for more than 500 years. For more than 1500 years, this site has held the believed remains of two of the earliest Christians and Jesu apostles: St. Philip and St. James the Younger - relics of the Holy Catholic Church... The skeletons are today far from complete. Only fragments of a tibia, a femur and a mummified foot remain. The tibia and foot are attributed to St. Philip, the femur to St. James. It appears likely that this has been the case since the sixth century... The researchers...

    Using a combination of archaeological and geological evidence, scientists have finally pinpointed the date of the infamous Tierra Blanca Joven eruption, which likely devastated Maya communities in what is now El Salvador. Ilopango volcano blew its stack 1,589 years ago—give or take a year or two—according to new research published this week in Proceedings of the National Academy of Sciences. That this volcano erupted well over 1,000 years ago was well established, but the new research finally firms up the date, in a paper that will be of interest to archaeologists, historians, geologists, and climate scientists. The Ilopango caldera is...
  • London pottery finds reveal Shoreditch agricultural past: Radiocarbon test of early Neolithic remains can pinpoint dates to a human life span 5,500 years ago

    It is perhaps best-known for its hipsters, but long before Shoreditch became avant garde, it was a place of agriculture and farmers according to evidence from a radiocarbon dating technique that has revealed details about Neolithic London. The technique proved that the most significant early Neolithic pottery discovered in London is 5,500 years old. It reveals for the first time that the city's prehistoric inhabitants led a less mobile, farming-based lifestyle than their hunter-gathering forebears. The research, published in Nature, reveals that an area around Shoreditch High Street was once populated by farmers herding their livestock across a once-green landscape....

    In 1983 a sponge diver found funny metal biscuits with ears at the ocean floor. That is how the excavation got started, Hirschfeld said. The ship carried ten tons of copper ingots, which after being analyzed, were determined to be from Cyprus. Each ingot weighs approximately 60 pounds, she said. She and her team also excavated glass ingots, tons of tin, and three Italian swords that were not part of the cargo of the ship. Among the 130 Canaanite jars they found, there were traces of wine in the jars and one was full of glass beads. The team also...

    Remains of a long dead house mouse have been found in the wreck of a Bronze Age royal ship. That makes it the earliest rodent stowaway ever recorded, and proof of how house mice spread around the world. Archaeologist Thomas Cucchi of the University of Durham, UK, identified a fragment of a mouse jaw in sediment from a ship that sank 3500 years ago off the coast of Turkey. The cargo of ebony, ivory, silver and gold - including a gold scarab with the name of the Egyptian queen Nefertiti - indicates it was a royal vessel. Because the cargo...

    The Limehouse Cut ^ | 30 October 2005 | Douglas J. Keenan
    The approach that was adopted for Anatolia, however, was to rely largely on what is called a "D-score". The D-score does not exist in statistics. It has been used solely with tree rings. D-scores do not have a mathematical derivation -- unlike t-scores, g-scores, and times series. In fact, D-scores were more or less just made up (in an unpublished 1987 thesis), and using them to evaluate a tree-ring match turns out to be little better than rolling dice... The most important of those dates was perhaps for wood from a shipwreck, which was claimed to resolve some of the...
