When archaeologists discovered the bones of a 9000-year-old human in a burial pit high in the Andes, they were impressed by a tool kit of 20 stone projectile points and blades stacked neatly by the person’s side. All signs pointed to the discovery of a high-status hunter. “Everybody was talking about how this was a great chief, a big man,” says archaeologist Randy Haas of the University of California (UC), Davis.

Then, bioarchaeologist Jim Watson of the University of Arizona noted that the bones were slender and light. “I think your hunter might be female,” he told Haas.

Now, the researchers report that the burial was indeed that of a female, challenging the long-standing “man the hunter” hypothesis. Her existence led them to reexamine reports of other ancient burials in the Americas, and they found 10 additional women buried with projectile points who may also have been hunters. “The message [of the new finding] is that women have always been able to hunt and have in fact hunted,” says archaeologist Bonnie Pitblado of the University of Oklahoma, Norman, who was not part of the study.

The “man the hunter hypothesis,” which prevailed after an influential symposium in Chicago in 1966, held that during the course of human evolution, men hunted and women gathered—and they seldom switched those gender roles. Some researchers challenged the notion, and ancient female warriors have been found recently, but archaeological evidence of women hunting has been scant. And the idea that all hunters were male has been bolstered by studies of the few present-day groups of hunter gatherers, such as the Hadza of Tanzania and San of southern Africa. In those cultures, men hunt large animals and women gather tubers, fruits, nuts, and seeds.

Haas and his team, including local Aymara colleagues, weren’t intending to study female hunters. They discovered the fossilized remains of six individuals in burial pits at the archaeological site of Wilamaya Patjxa at 3925 meters’ altitude on the windswept altiplano of southern Peru. Two people were buried with stone tools. One person, likely 17 to 19 years old, was accompanied by four projectile points that would have been attached to short spears for hunting, several cutting blades, a possible knife, and scraper tools likely used for processing animal hides and meat. The 20 stone tools and ochre, which can be used to tan hides, were neatly stacked next to the top of one individual’s thigh bone, as if they had been held in a leather pouch that had disintegrated. Another person, likely 25 to 35 years old at death, was buried with two projectile points. The pits also held bone fragments of Andean deer and camelids, such as vicuña or guanaco.

The researchers figured out the sex of the bones using a new forensics method developed by co-author Glendon Parker of UC Davis. The technique analyzes whether an individual’s tooth enamel carries a male or female version of a protein called amelogenin. The individual with the impressive toolkit was female; the other person with hunting tools was male. Studies of isotopes of carbon and nitrogen in the woman’s teeth showed she ate a typical hunter’s diet of animal meat and plants.

Others find the evidence of a female hunter convincing. “It’s a smoking gun,” says archaeologist Meg Conkey of UC Berkeley, who was not part of the study. “But skeptics might say it’s a one-off.”

Haas anticipated that concern: In a search of reports of burials at 107 other sites in the Americas older than 8000 years, he found 10 other women and 16 men also buried with hunting tools. This meta-analysis suggests “early big-game hunting was likely gender neutral,” he and his colleagues report today in Science Advances.

Robert Kelly of the University of Wyoming applauds the discovery of the female hunter but isn’t convinced by many of the other potential cases. He points out that having tools in the same grave as a person doesn’t always mean they used them in life. Two burials were female infants found with hunting implements, for example. Buried tools could also have been offerings from male hunters to express their sorrow, he says.

Pitblado says that even if not all of those female remains belonged to hunters, the meta-analysis suggests women have long been capable of hunting, and provides hints about where to look more closely for evidence. Human ecologist Eugenia Gayo of the University of Chile agrees. Such research could help answer questions such as “What were the type of environments where everybody got involved in the hunting?” she says.

It shouldn’t be surprising that women could hunt, Pitblado adds. “These women were living high up in the Andes, at 13,000 feet full time,” she says. “If you can do that, surely you can bring down a deer.”

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
