Straws, sweets and a Godzilla thermos wrapper: plastic found in Iron Age reconstruction roundhouses – CTV News

Published

 on


TORONTO —
When a group of archeologists excavated reconstructed Iron Age roundhouses that had been used in historical reenactments in Wales for more than 30 years, they expected to learn about the decay processes of these structures.

What they didn’t expect was to discover so much plastic.

More than 2,300 individual pieces of plastic — candy wrappers, straws, a Motorola phone battery, etc. — were found in the ground by archeologists excavating the reconstruction sites.

The Plastic Age encroaching on the Iron Age.

A paper published in the journal Antiquity this week dives into the finds, as well as the implications for what future archeological digs could look like, given the ubiquity of plastic in our society today.

THE PLACE

Castell Henllys Iron Age Village is both an archeological site, and a tourist attraction in Wales. The hill fort consists of reconstructed roundhouses that visitors can walk through while learning about the Iron Age, the main draw being that the roundhouses have been reconstructed on the very spot that the structures stood around 2,000 years ago.

As well as attracting tourists, the site is also frequently visited by schools in the area as part of their history teachings on the Iron Age Celts.

But in 2017 and 2018, two reconstructed roundhouses at Castell Henllys came to the end of their heritage life, after 35 and 30 years of use respectively.

The structures were demolished, and the Pembrokeshire Coast National Park — which runs the site — arranged for them to be excavated, “appreciating the value of an archeological perspective for the redesign and rebuilding, and the research significance, of these long-term experimental structures.”

The roundhouses themselves look like pointy hats resting on the ground, with conical thatched roofs. They were used year-round, and were well-maintained. One even served as the location of a short-lived reality TV show called ‘Surviving The Iron Age,’ in 2001, where participants attempted to live as their ancestors did in the Iron Age.

roundhouses

The first roundhouse, referred to by the site as the Cookhouse, was 9.5 metres in diameter, and was first erected in 1982. It was predominantly used to show what a domestic Iron Age house would’ve looked like, with a central hearth, beds and storage, as well as a portable loom for weaving demonstrations.

“Despite the Cookhouse being the most frequently visited roundhouse at the site, relatively little debris accumulated within it,” the paper stated, adding that this was due to the fact that people visited, walked around, and left, instead of partaking in any activities there that might generate trash.

The second roundhouse, called the Earthwatch roundhouse, was erected in 1984 and contained “curved benches around the hearth […] on which visitors—particularly school parties—could sit.

When the roundhouses were demolished ahead of excavation, the furniture was removed and the roof was taken down, but parts of the standing wall remained, as did debris in the middle of the structure.

THE PLASTIC

The roundhouses had been toured by the public for 30 to 35 years, and all of those years showed in the different types of plastic debris found in the excavation.

In the Cookhouse, archeologists found plastic tags with the word “FERTO” on them — the name of a lake in Hungary. The tags had come with bundles of reeds from Hungary to help build the roundhouses with other, local materials.

A metal bowl with plastic tubs of face paint and a tin of beeswax represented materials that had been used by reconstruction actors in demonstrations over the years.

But much of the plastic in both roundhouses was thought to come from visitors.

The vast majority of the plastic found was in the Earthwatch roundhouse. Researchers suggest this was because it was less well-lit, and visitors spent longer in this space.

“Here, they were told stories about the Iron Age, and, in bad weather, would eat their packed lunches,” the paper stated.

Archeologists found plastic cutlery, and an assortment of food related wrappers, revealing the culinary habits of the schoolchildren and other visitors who came to the roundhouses over the past few decades.

According to the wrappers found, a few visitors had snacked on CheeStrings, Pepperamis and Lunchables pizza.

“A complete Golden Wonder noodles foil lid and two other foil-lid fragments were also found,” the paper stated. “A healthier eating choice is represented by 21 plasticized apple stickers, revealing a range of popular apple varieties, including Braeburn, Cox, Golden Delicious, Granny Smith, Pacific Beauty, Pink Lady and Royal Gala.”

Other finds included plastic clothing items, one pair of glasses, “an almost complete Godzilla-themed thermos wrapper,” bottle caps, sealing strips for bottles, and plastic straws. One of the most common types of plastic found was the plastic wrapping that affixes straws to drink cartons.

1998 Godzilla wrapper

“There were 18 plastic straws and 210 fragments of straw packaging,” the paper said.

Candy wrappers made up the biggest single category, however, with around 1,100 fragments found between both roundhouses.

There was no obvious signs of the plastic having decayed at all, which made sense given the relatively short time period they had been in the ground.

In the Earthwatch roundhouse, some plastic was found trampled into the clay floor itself, packed in. Most debris accumulated around the edge of the structure and underneath furniture, in both roundhouses.

Many of the plastic items were in pieces, or torn in some way, meaning several could belong to the same original plastic bag or wrapper.

“The figures thus represent plastic fragments rather than original plastic or plasticized items,” the paper clarified.

OUR PLASTIC ARCHEOLOGICAL FOOTPRINT

When archeologists in the future look back on our lives now, plastic may be the biggest takeaway and the largest indication of how we lived, this study suggests.

For this specific example, the plastic found at the Earthwatch roundhouse “vividly reveals the consumption of packed lunches by schoolchildren.

“At Castell Henllys, these items comprise the dominant archaeological signature of contemporary heritage-visiting activity,” researchers wrote.

Plastic wrappers

Researchers pointed out that while there has been a lot of research into how plastic winds up in oceans, lakes and rivers, there has been much less research into the plastic presence in terrestrial locations.

Some contemporary archeology studies have noted plastic in areas where it is expected to collect, such as urban areas and landfills, the researchers stated, but “this study concentrates on what might be considered a ‘benign’ environment.”

These roundhouses — which were built with Iron Age materials and were far away from modern life — were cleaned frequently due to the number of visitors and the year-round use. And yet plastic found its way in.

“The high prevalence of plastic at Castell Henllys is therefore particularly poignant,” the paper said, saying the “sheer quantity of the plastic recovered […] was unexpected.”

Several scholars have proposed before that the “Plastic Age” should be the term for contemporary society due to how the advent of plastic has changed society so much and become such a staple in every corner of our lives.

While this term has not overtaken others used for our current era, it’s clear that an abundance of plastic in the archeological record may help future archeologists date artifacts and sites.

“With many initiatives now pushing to switch from disposable plastic and plasticized items, this may be a narrow but archaeologically distinctive chronological horizon,” researchers wrote.

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.”
