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

Published

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.

‘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.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
