In 2009, the city of London embarked on a massive infrastructure project: a 73-mile underground railway network called the Elizabeth Line that will ultimately boost urban train capacity by 10 percent. Slated to be up and running by 2018, the undertaking allowed archaeologists to take an unprecedented peek at swathes of subterranean London, and yielded plenty of cool historic treasures from various periods. Here's a small sampling of the finds.

1. A GRAVEYARD CONTAINING VICTIMS OF THE BLACK DEATH

Crossrail

While excavating London's Charterhouse Square in 2013, archaeologists unearthed dozens of skeletons. Scientists analyzed the remains and discovered that some of them belonged to victims of the Black Death—a.k.a. bubonic plague—who succumbed to pandemics that swept 14th- and 15th-century England.

Teeth contained traces of DNA from the plague bacterium Yersinia pestis, and radio-carbon dating indicated that the burial ground had been used during two outbreaks of plague, one from 1348 to 1350 and another during the 1430s. The skeletons also showed signs of poor diets and hard lifestyles, which might have been contributing factors for why Londoners were so susceptible to the plague.

But the so-called plague pit didn't just contain those who'd succumbed to disease. Not only were some bodies plague-free, "what they found was, not bodies tumbled together as they'd expected, but rather orderly burials with people laid in rows with their bodies orientated in one direction," historian Gillian Tindall told The Guardian. This suggests not all of them died due to plague but from other, more everyday causes.

2. AN 8000-YEAR-OLD STONE TOOL

While digging at North Woolrich, in southeast London, archaeologists discovered a Mesolithic-era site along the Thames where early humans are thought to have crafted tools around 8500 to 6000 years ago. The encampment had traces of campfires and flint scatters, and experts recovered 150 pieces of flint, including an 8000-year-old stone tool.

"This is a unique and exciting find that reveals evidence of humans returning to England and in particular the Thames Valley after a long hiatus during the Ice Age," Crossrail lead archaeologist Jay Carver said in a news release. "It is one of a handful of archaeology sites uncovered that confirms humans lived in the Thames Valley at this time. The concentration of flint pieces shows that this was an exceptionally important location for sourcing materials to make tools that were used by early Londoners who lived and hunted on Thames Estuary islands."

3. A VULGAR VICTORIAN CHAMBER POT

While excavating the Stepney Green station in East London, archaeologists came across a 19th-century cesspit dating to sometime after 1850. The waste hole was filled with tobacco pipes and fragments of pots, including a raunchy Victorian chamber pot. It was once likely kept under a bed, and allowed for its owner to do their business in private during the evening hours.

The pot's bottom contains a cartoon of a grimacing man, encircled by the phrase "Oh what I see/I will not tell." Witty cursive lines once covered the exterior of the broken vessel. Archaeologists were able to decipher one line, which read "… when you in it want to p-s/ Remember they who gave you this."

4. A TUDOR ERA BOWLING BALL (OR SKITTLES BALL)

In addition to the aforementioned cesspit, excavations at Stepney Green also revealed a 15th-century Tudor manor house, complete with moat. Originally home to a rich family named Fenne, it was once called King John's Court or Palace, and later became known as the Worcester House after its owner the Marquis of Worcester.

In 2013, archaeologists excavated the home's foundations, moat, and boundary walls. Inside the moat they discovered a wooden ball made from willow, which was likely either used for bowling or skittles, a European lawn game. Other recovered items included fine glassware, tableware, and cooking and storage vessels, all of which were buried when the moat was either destroyed or filled in.

5. A 55-MILLION-YEAR-OLD PIECE OF AMBER

Crossrail

Slated to open in late 2018, London's new Canary Wharf business district station is located deep below a mixed-use development called Crossrail Place. While tunneling at Canary Wharf was too deep to disturb any buried relics, engineers were still able to retrieve a piece of 55-million-year-old amber from nearly 50 feet below the site's dock bed before construction began. It's the oldest amber to have ever been found in London, and is also notable considering that amber isn't often found in the UK to begin with.

Amber, or fossilized tree resin, takes millions of years and proper burial conditions to form. These preserved relics often contain prehistoric plants and creatures, suspended in the clear material. Experts said they plan to analyze the Canary Wharf amber to learn more about prehistoric environmental conditions and vegetation. The fossil also contained bubbles of trapped gas, which scientists said might yield new scientific insights about global warming.

6. A RARE ROMAN MEDALLION

Archaeologists excavating Crossrail's Liverpool Street site discovered more than 100 mostly-copper Roman coins, along with a handful of silver currency. They ranged in date from 43 CE, during the reign of Emperor Claudius, to 348 CE.

One of the most exciting discoveries among these coins was a rare bronze medallion that was issued to mark the New Year in 245 CE. Presented by Emperor Phillip I (also called Philip the Arab) to a high-ranking government official, it's only the second example of its kind that's ever been found, according to The Guardian.

"You wonder how it got there, who brought it with them, and then how did they lose it—were they heartbroken?" speculated Jackie Keily, a curator at the Museum of London who organized an exhibition of 500 Crossrail artifacts in 2017.

7. A CLUSTER OF ROMAN SKULLS

Crossrail

In 2013, Crossrail workers found Roman pottery and around 20 Roman skulls while working on the Liverpool Street station site. Other Roman skulls had been found in the area, along the historic River Walbrook, and some speculated that they belonged to rebels led by the Iceni warrior-queen Boudicca, who revolted against the Roman Empire during the 1st century CE. But since the newly unearthed skulls were found in sediment that had accumulated in a bend of the river, archaeologists believe that they likely washed out of an eroded Roman cemetery long ago. Moreover, the skulls appear to date to after the uprising.

8. HEADSTONES OF VICTIMS OF THE GREAT PLAGUE

Crossrail

On September 2, 1665, a girl named Mary Godfree succumbed to the plague—one of 95 people from the same church parish who died from the disease that day. She was remembered solely by a line in a burial register until October 2015, when archaeologists discovered her limestone burial stone while excavating the new Liverpool Street Crossrail station site.

The area was originally home to the historic New Churchyard burial ground, also called the Bedlam burial ground. There, archaeologists discovered a mass grave, along with the remnants of 10 stone markers. Godfree's headstone didn't mark the presence of her actual grave, as the headstone had been removed sometime during the 18th century and reused in the foundation of a wall. Still, it revealed new insights into how and where the rediscovered Londoner was buried, and what burial conditions were like during the Great Plague.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

Humans First Arrived in North America 30,000 Years Ago, New Studies Suggest

People occupied North America by roughly 11,000 BCE, but the exact timeline of how early humans first arrived on the continent is contested. Two new studies suggest that humans were living in North America as far back as 30,000 years ago—preceding some earlier estimates by more than 15,000 years.

According to the traditional narrative, the first North Americans were big game hunters who crossed a land bridge connecting Asia to North America around 13,000 years ago. They left behind distinct, fluted arrowheads and bone and ivory tools that were dubbed “Clovis” tools. “This narrative, known as ‘Clovis-first,’ was widely accepted for most of the 20th century until new archaeological evidence showed that humans were present in the continent before Clovis,” Lorena Becerra-Valdivia, an archaeological scientist with the Universities of Oxford and New South Wales and co-author of the new studies, tells Mental Floss. “Within academia, an earlier arrival of 16,000-15,000 years ago was generally accepted.”

Her new analysis pushes back that date by several millennia. The study, “The Timing and Effect of the Earliest Human Arrivals in North America,” published in the journal Nature, looks at radiocarbon and luminescence data from Beringia, a region that historically linked Russia and Alaska, and North America. A statistical model built with this data indicates that a significant human population was living on the continent long before the Clovis era. According to the study, these humans were likely present before, during, and after the Last Glacial Maximum—the period when ice sheets covered much of North America 26,000 to 19,000 years ago.

These findings also contradict the land bridge theory. Rather than making a straightforward journey from Asia to North America and populating the southern half of the continent as the Clovis people were thought to have done, the first humans may have entered the Americas by traveling down the Pacific Coast. “These are paradigm-shifting results that shape our understanding of the initial dispersal of modern humans into Americas,” Becerra-Valdivia says. “They suggest exciting and interesting possibilities for what likely was a complex and dynamic process.”

The second, related study in Nature, ”Evidence of Human Occupation in Mexico Around the Last Glacial Maximum,” supports this new narrative. In it, researchers from institutes in Mexico, the UK, and other countries share artifacts and environmental DNA uncovered from Chiquihuite Cave—a high-altitude cave in Zacatecas, central Mexico. The tools, plant remains, and environmental DNA collected there paint of picture of human life dating back 13,000 to 30,000 years ago. The evidence shows that the site was more than just a stopping point, and the people living there had adapted to the high altitudes and harsh mountain landscape.

The two studies not only offer insight on when the first North Americans arrived on the continent, but who they were and how they lived. The Americas would have looked a lot different to humans during the Last Glacial Maximum than they did to the Clovis people millennia later. The fact that the first North Americans left behind far fewer artifacts than the Clovis people shows that their populations stayed relatively small. “Humans at Chiquihuite Cave would have faced the harshness of the Last Glacial Maximum, the peak of the last Ice Age, which would have kept their population at a low density,” Becerra-Valdivia says. “Clovis peoples, in contrast, thrived well after the last Ice Age, expanding widely through the continent during a period of globally warmer temperatures. Their life ways and subsistence patterns, therefore, would have been very different.”
