'Kind of incredible': Researchers reveal details of mummified ice age wolf pup found in Yukon – CBC.ca

Scientists who have been studying a rare, perfectly preserved ancient wolf pup found in Yukon are sharing some of their findings for the first time.

The 57,000-year-old animal, discovered in the gold fields of Yukon in 2016, is the most complete mummified grey wolf of this era ever found. 

“She’s just so complete,” said Julie Meachen, a vertebrate paleontologist from Des Moines University in Iowa and lead author of the new study published this week in the journal Current Biology. “She’s so amazing. She’s so intact. I mean she even has her fur. Everything is there.”

The researchers were amazed to discover even the pup’s internal organs were intact. 

“We can just learn so much more from an animal with skin and fur and organs than we can with just bones,” Meachen said. “This is kind of incredible that we can get all this detail from her when she lived so long ago.” 

‘She’s just so complete. She’s so amazing. She’s so intact,’ said researcher Julie Meachen of Des Moines University in Iowa, seen here with Zhùr and veterinarian Jess Heath at a Whitehorse vet clinic in 2019. Heath is one of several co-authors of the new research paper. (Government of Yukon)

Through a variety of testing and analysis, the team of researchers was able to determine the pup — named Zhùr, which means “wolf” in the local Indigenous Hän language — was just seven weeks old when it died in its den. 

Genetic testing also revealed the wolf is not related to wolves found in North America today. 

“We learned she is very closely related to ice age wolves in Europe,” said Yukon paleontologist Grant Zazula.

“And that’s really interesting because that tells us that there was a major population change that happened in North America with grey wolves at the end of the ice age.”

The scientists say they were most surprised to discover something about the diet of the little wolf. The animal’s last meal wasn’t bison or caribou or muskox as they had expected of the carnivore. It was fish.

“Based on the analysis of chemical components in her hair and other tissues, we were able to determine what her last meal was,” said Zazula. 

He says looking at things such as the ratio of carbon and nitrogen preserved in the tissue, it was clear the pup was eating aquatic species, most likely salmon. 

Culturally significant 

Zhùr is significant not only to the scientists but also to the Tr’ondëk Hwëch’in First Nation in Yukon. 

“We are connected to this wolf pup,” says Debbie Nagano, the director of heritage for the Tr’ondëk Hwëch’in and a member of the First Nation’s wolf clan. 

Soon after the initial discovery, Zhùr was brought back to Dawson City for a special blessing ceremony with First Nations elders and was given a name. Nagano says before the animal went off for analysis, the First Nation worked with the scientists to ensure Zhùr wouldn’t be treated just as a specimen.

“That side is quite important to us,” Nagano said. “There is a connection to it. We don’t want it to be just handled in the view of, ‘It’s just an artifact.’

“We really want it to be able to have the respect behind it also. Not in the way it’s respected physically; it also need to be respected spiritually.” 

Nagano says the discovery of Zhùr has also helped improve the relationships between the First Nation and scientists, and also with the government and the mining community. 

“This wolf pup is bringing us together in a good way, that we can all learn from it,” she said. “That part is a good way to be thankful for this wolf pup.” 

Rare find

For their part, the scientists are also grateful to the placer miner who first discovered Zhùr, in 2016.

Neil Loveless came across the animal thawing out of the permafrost. 

“I just saw this thing that didn’t quite look right,” he recalled. “I picked it up and to be honest, I thought maybe it was like an old, like a puppy or something … that had fallen down the mine shaft.” 

He put the remains in a gold pan and later in a freezer until a paleontologist arrived to have a look.

The scientists say it’s that kind of collaboration with the mining community that makes their research possible. 

Ice-age remains are commonly dug out of the permafrost in Yukon — bones of mammoths, bison and horses — but a complete specimen like Zhùr is very rare, at least for now. 

Meachen hopes there may be more to find. 

“As global warming continues to thaw the permafrost, one silver lining is that other exceptionally preserved frozen mummies will likely be discovered, providing new windows into the past,” she said.

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.”
