Fossil footprints in New Mexico reveal what may be oldest known handcarts, researchers say
Follow-up study confirms age of fossil human footprints found at White Sands National Park
The research was published in the journal 'Quaternary Science Advances' in January and was compiled by a team of experts from across the United States and the United Kingdom. Two of those researchers were Sally Reynolds, an associate professor in Hominin Palaeoecology at Bournemouth University, and her husband Matthew Bennett, a professor of Environmental and Geographical Sciences at Bournemouth University.
'We found these traces pre-COVID, and they were just these long drag marks in the sand,' Reynolds said. 'So we were trying to think of the most logical explanations for these very few drag structures that we found. But over the years, they just kept popping up. Different places, different orientations, different locations.'
Reynolds and Bennett worked with other researchers to figure out what the drag marks alongside the 21,000 to 23,000-year-old footprints might be. The team first considered that the marks may have been from people pulling a canoe or branches for firewood, but they ruled it out after reviewing other research.
'By process of elimination, we thought, you know what? It makes most sense that people are using this technology to travel from an area of intense activity, probably back to their living area, which is how we came up with the idea of hand carts,' Reynolds explained.
According to the research, the carts, or travois, may have been made of wooden poles that were dragged.
Researchers have not found any evidence that animals were involved in pulling these carts, which suggests that they were pulled by humans. 'So it was clear that unlike the later Native American travois, which you may have seen pictures of, are drawn by horses or donkeys or dogs, these were drawn by humans. And suddenly we realized we were looking at the earliest transport technology, basically a wheelbarrow, but without the wheel,' said Reynolds.
Some of the footprints found near the drag marks may have been from children, due to their smaller size. Reynolds inferred that the children may have interacted with the travois. 'It just enabled, I think, the humans, the families who were there to collect more stuff,' Reynolds said, likening the interaction to children playing and trying to climb on carts at the supermarket.
'I like the idea of the kids just trying to run around these travois while they were being pulled and find a way to get themselves on it somehow,' Reynolds added.
The researchers did experimental work by making a travois to replicate the drag marks found in White Sands National Park in southern New Mexico. Tests of the travois were done on mudflats in Maine and in the United Kingdom. Examples from the tests were published in the journal 'Quaternary Science Advances' and can be found below.
Looking ahead, Reynolds said she anticipates that more evidence of these trackways will be found at White Sands National Park. She also hopes to find out what materials, likely wood, may have been used to make the transportation devices and what items, including food, people may have gathered in the area thousands of years ago.
At this point, the team of researchers felt it was time to share their best guess of what happened.'We've reached a point where we know as much as we're ever going to know. We want to just share our current understanding of these traces with the wider community. Who knows, perhaps somebody out there has got a different interpretation or perhaps some sort of corroboration that they could offer and something that ultimately will allow that part of the work to be carried forward,' Reynolds said.

Bones in Norway Cave Reveal Chilling Fate of Ice Age Animals
For 75,000 years, the remnants of a diverse ecosystem of Ice Age animals have lain hidden in the shelter of Arne Qvam Cave in Norway. Scientists have only just begun to grasp the full scope of its contents, which are the oldest evidence we have describing the diversity of animals that flourished in one of the glacial period's warmer stints. This rare and remarkably extensive archive of ancient Arctic fauna covers a wide spectrum of vertebrates, from small mammals like the collared lemmings (Dicrostonyx torquatus) and voles (Alexandromys oeconomus) that scurried across the tundra, marine and freshwater fish, and more than 20 bird species, to the landscape's largest marine mammals, like whales, walruses, and even a polar bear. Related link: "We have very little evidence of what Arctic life was like in this period because of the lack of preserved remains over 10,000 years old," says evolutionary biologist Sanne Boessenkool of the University of Oslo. This find fills a "significant void in our understanding of biodiversity and the environment during a period of dramatic climate change," Boessenkool and team write in their paper describing the finds. The cave was concealed within a mountain until the 1990s, when a tunnel built for mining exposed the secret chamber. Even then, large excavations were not carried out until 2021 and 2022, when the animal remains emerged from the lower layers of sedimentary rock. The collared lemmings were a particularly exciting find: this species is now extinct in Europe, and until now, the only signs they had ever lived there were from Scandinavia. The remains of freshwater fish suggest there were lakes and rivers in the tundra environment, while bowhead whales and walruses would have required sea ice. This probably wasn't present year-round, however, because the harbour porpoises also found in the cave avoid waters that have frozen over. These animals were living in a period of global cooling. The entire ecosystem seems to have depended on melting glaciers that provided fresh water and exposed the ocean; once the landscape froze over once again, the biodiversity disappeared, suggesting the mix of animals were unable to migrate or adapt to the colder, drier environment. "This highlights how cold adapted species struggle to adapt to major climatic events. This has a direct link to the challenges they are facing in the Arctic today as the climate warms at a rapid pace," lead author and Bournemouth University zooarchaeologist Sam Walker says. "The habitats these animals in the region live in today are much more fractured than 75,000 years ago, so it is even harder for animal populations to move and adapt." While many of these kinds of animals can still be found in the Arctic today, they no longer live in the cave's vicinity. When the researchers compared the bones' mitochondrial DNA with those of extant populations, they found none of the ancient lineages had survived when the glaciers froze up again. But, as Boessenkool points out, "this was a shift to a colder [climate], not a period of warming that we are facing today. "And these are cold-adapted species – so if they struggled to cope with colder periods in the past, it will be even harder for these species to adapt to a warming climate," she says.

75,000 years old: Europe's oldest Arctic animal community discovered in Norway cave
The bones of a vast community of 46 animals in a 75,000-year-old cave in Norway have provided a stunning and rare snapshot of a vanished Arctic world. Researchers only recently discovered and explored Arne Ovamgrotta, but the ancient cave has held a significant collection of animal bones for 75,000 years. Researchers confirmed the finding of 46 different types of animals, hinting at the existence of a large community banding together to weather the cold. Their remains represent the oldest example of an animal community in the European Arctic during this warmer period of the Ice Age and provide an unprecedented first look at a community struggling, if not failing to survive, climate change. According to a new study published in the Proceedings of the National Academy of Sciences (PNAS), the study authors believe the newly discovered bones will feed conservation efforts today by helping researchers understand 'resilience and extinction risk in the present.' These animals didn't survive the Ice Age According to study author Dr. Sam Walker of Bournemouth University and the University of Oslo, this 'rare snapshot of a vanished Arctic world' included an impressive, if not astonishing, assemblage of bones. Among the animals were polar bears, walruses, bowhead whales, Atlantic puffins, common eiders, rock ptarmigans, and Atlantic cod. Additionally, as per a press release, they found collared lemmings, which no one had ever uncovered in Scandavia previously, a species now extinct in Europe. The massive number communicated to researchers that temperatures had increased significantly enough 75,000 years ago to allow these animals passage to the cave. Reindeer, porpoise, and freshwater fish bones further told researchers that rivers and lakes returned to this area. 'The cave has now revealed a diverse mix of animals in a coastal environment representing both the marine and the terrestrial environment,' according to a press release. A picture of this region on Earth became clearer than ever as remains over 10,000 years old are a rare find. This underexplored period during the Ice Age saw the melting of ice, which was enough to support a struggling community of animals. Warnings for our future DNA testing found that these animals did not survive when temperatures dropped back to bone-chilling and fatal degrees. Harsh sheets of ice returned to the region, preventing any possibility of migrating elsewhere, as per Popsci. 'This highlights how cold-adapted species struggle to adapt to major climatic events. This has a direct link to the challenges they are facing in the Arctic today as the climate warms at a rapid pace,' said Dr Walker. 'The habitats these animals in the region live in today are much more fractured than 75,000 years ago, so it is even harder for animal populations to move and adapt,' Dr. Walker continued. 'It is also important to note that this was a shift to a colder, not a period of warming, that we are facing today,' senior author Professor Boessenkool says. 'And these are cold-adapted species – so if they struggled to cope with colder periods in the past, it will be even harder for these species to adapt to a warming climate,' she concludes in a press release.

When is the next full moon? Sturgeon Moon will rise over Mississippi soon in August 2025
The August full moon will rise over Mississippi soon. But stargazers have other astronomical events to look forward to this month. Showy fireballs and shooting stars will be visible at night over Mississippi until late August. Three meteor showers are happening now. The Perseid is the most famous of the trio. According to the American Meteor Society, it runs from about July 17 to Aug. 23. The alpha Capricornids are still in progress and will be active through about Aug. 12, according to the American Meteor Society. The Delta Aquariid Meteor Shower will also be visible from July 18 through around Aug. 12. Falling stars can be visible from evening through dawn, meaning you don't have to stay up late for this stargazing, though the best times are between midnight and dawn. Can the full moon keep you from seeing the celestial show? Here's what to know about the August full moon and when you can try to get the best view of the meteor showers over Mississippi. When is the August full moon? The full moon in August, called the "Sturgeon Moon," will be on Aug. 9, 2025. Peak illumination will be 2:55 a.m. CT, according to Farmer's Almanac. Moonrise in Jackson will be at 7:48 p.m. CT, on Aug. 8, according to That'll be shortly after sunset around 7:51 p.m. Why is it called the Sturgeon Moon? According to Farmer's Almanac, it's called the Sturgeon Moon because lake sturgeon were plentiful this time of year. The fish were an important food for Native American tribes. Other names for this moon include: Black Cherries Moon Corn Is in the Silk Moon Corn Moon Dry Moon Feather Shedding Moon Grain Moon Green Corn Moon Hot Moon Hunger Moon Lightning Moon Plum Moon More: When to watch Perseid meteor shower light up the sky tonight in Mississippi What nights will have the most meteors in August? The Perseids will peak around Aug. 12-13, according to the American Meteor Society. Peak periods for these showers were around July 29-30, but they're still putting on a show. It's just not the maximum number of meteors you might see. What are the best nights to see shooting stars in August? The worst nights for viewing meteor showers will be in the days surrounding the full moon. NASA released an article explaining that the full moon will be 84% full on the peak nights of the Perseids. You still might see a few bright meteors before dawn, but overall visibility will be low on the nights when the most will be shooting across the sky. The new moon is Aug. 23, so the darker nights as the moon wanes will be your best bet for a night sky dark enough to see the end of the Perseid. What are the names of other full moons throughout the year? Other popular nicknames for monthly full moons, according to the Old Farmer's Almanac, include: Wolf Moon (January) Snow Moon (February) Worm Moon (March) Pink Moon (April) Flower Moon (May) Strawberry Moon (June) Sturgeon Moon (August) Corn Moon (September) Hunter's Moon (October) Beaver Moon (November) Cold Moon (December) Why do we see moon phases? There are four lunar phases based on the Earth's position between the sun and the moon. A full moon means the entire visible side of the moon facing Earth is reflecting sunlight. When less of the moon gets light, it's dark (a new moon) or waxing or waning. Full moons normally happen 29.5 days apart and once a month. Rarely are there two full moons in a single month. It's called a "blue moon," and the next one will be on May 31, 2026. Contributing: Mary Walrath-Holdridge Bonnie Bolden is the Deep South Connect reporter for Mississippi with Gannett/USA Today.
