Meet The Megatherium: The Adorable 13-Foot Sloth That Ruled The Prehistoric Amazon

Meet The Megatherium: The Adorable 13-Foot Sloth That Ruled The Prehistoric Amazon

An artist’s rendering of a now-extinct Megatherium.

The year is 9,000 B.C. Humongous cave bears, saber-toothed tigers, and massive-antlered Irish elk roam the grasslands and forests of South America, but the biggest of all is the Megatherium, an elephant-sized ground sloth.

The Megatherium was one of the largest ground mammals ever to have existed. The Megatherium dominated the continent’s southern grasslands and lightly forested areas and was something of a king of the mammals for thousands of years before a mass extinction event wiped it from the planet.

Or did it?

Rediscovering The Megatherium

It would not be until 1788 that the Megatherium would be seen again after the mass extinction event that wiped out pre-historic animals like the wooly mammoth and saber-toothed tiger, too.

It was then that an archaeologist named Manuel Torres discovered a rare fossil specimen on the banks of the Luján River in eastern Argentina. Though he did not immediately recognize it, he deemed it worth further study and sent it back to his base of study at the Museo Nacional de Ciencias Naturales (The Spanish National Museum of Natural History) in Madrid, Spain. There, it was assembled into its most likely arrangement and mounted for display. A museum employee also created a thorough sketch of the animal to further study it.

The original specimen found by Manuel Torres on display in Madrid.

Before long, the fossil caught the eye of esteemed French paleontologist Georges Cuvier. Cuvier was intrigued by the sketch of the creature and used it to further explore its anatomy and taxonomy, and over time, he managed to create a more complete picture of the Megatherium’s history. In 1796, just eight years after the Megatherium had been discovered, Cuvier published the first paper on it.

In this paper, Cuvier theorized that the Megatherium was a giant sloth, perhaps an early ancestor of the modern equivalent. Initially, he believed that the Megatherium used its claws to climb trees as modern-day sloths did. However, he later amended his theory and hypothesized instead that the sloth was much too large to climb trees and likely used its claws to dig subterranean holes and tunnels.

With this explanation, a picture of the Megatherium as it existed began to form; a sloth the size of an elephant, with giant, powerful claws, that lived mostly on and under the ground. With further study, scientists began to discover its habitat, diet, and reproductive cycle, and the picture became ever clearer.

The Megatherium likely lived across the continent of South America, from southern Argentina all the way to Colombia. Full grown, individual creatures likely weighed upwards of four tons — the weight of the average male elephant — making it the largest land mammal second only to the wooly mammoth. It probably walked most of its life on four legs, though it is believed that it could stand on its hind legs in order to reach treetops and high foliage to feed its herbivorous diet. When it stood, the Megatherium would have been upwards of 13 feet tall.

Due to its immense size, it’s likely that Megatherium moved slowly like the sloths of today. It was likely one of the slowest creatures in its environment. In looks, it was quite similar to the modern sloth, though with facial characteristics of another one of its descendants, the anteater. In fact, it was in part Megatherium’s resemblance to more modern creatures that got Darwin thinking about his theory of evolution.

The Megatherium lived in large groups, though individual fossils have been found in isolated locations such as caves. It gave birth to live young, as most other mammals do, and likely continued living in familial groups while their young matured. Due to the lack of predators – they outweighed (and could likely kill) saber-toothed cats and other small carnivores – they lived a quiet and probably diurnal lifestyle.

Further, the Megatherium wasn’t much of a picky eater. The gigantic herbivores didn’t have to compete with smaller mammals for food as they had the advantage of height and procuring food from distances that smaller mammals simply couldn’t. They could tolerate and adapt to various types of plants as well as allegedly nibble on the occasional carcass, which allowed the Megatherium to migrate and thrive all over the continent — for 5.3 million years.

So what, or perhaps who, led to this resilient mammalian force’s extinction?

Extinction And Possible Survival

In roughly 8,500 B.C., the earth experienced a “Quaternary extinction event” during which most of the earth’s large mammals disappeared.

The Irish elk and saber-toothed tiger went extinct during this time as well as mammoths within the confines of continents, as some survived for several thousand more years in remote island areas. And, of course, the Megatherium went extinct during this time as well. These giant ground sloths were thought to have survived in more remote areas for at least another 5,000 years following this extinction, though.

Scientists are still not entirely sure what accounts for this mass extinctionas it does occur simultaneously with glacial-interglacial climate change. Instead, the extinction of the Megatherium seems more to have been the work of the emergence of mankind. Indeed, Megatherium fossils have been found with cut marks on them, suggesting that they were hunted by humans. Whatever the reasons for their disappearance, scientists have long believed that the elephant-sized sloths have been out of commission for at least 4,000 years.

However, rumors of giant sloths living deep in the jungles of South America have emerged. Those who live in and around the Amazon rainforest have long passed down stories of a dangerous beast they call the “mapinguari,” a giant sloth-like creature who is over seven feet tall, with matted fur and large, sharp claws. They claim it tramples foliage and brush and roars out of a giant, second mouth on its stomach.

Stomach-mouth aside, the description of the mapinguari is actually quite similar to descriptions of the Megatherium, and indeed several drawings of the mapinguari are hard to discern from those of the Megatherium. Some experts have theorized that the initial mapinguari sightings many years ago may, in fact, have been Megatherium that survived extinction by sequestering themselves within the shelter of the rainforest.

Artist’s rendering of what the giant sloth-like mapinguari could have looked like.

As many theorize that the mass extinction event was, in part, caused by a human invasion of their habitat, it would make sense that some could survive by avoiding populated areas. If the Megatherium truly did evade extinction, then the modern-day interpretation of the mapinguari is most likely an exaggerated report blown out of proportion through a generations-long game of telephone.

However, it could always be the case that the Megatherium truly did go extinct all those years ago and that the mapinguari, with its fetid breath and giant stomach-mouth, is truly roaming the Amazon and we are all in terrible danger.

Newgrange: The Massive Irish Tomb That’s Older Than The Pyramids

Newgrange: The Massive Irish Tomb That’s Older Than The Pyramids

Yep, 5,000 years. That’s older than Stonehenge. It’s older than the great Egyptian pyramids, too. And five millennia later, it hasn’t lost any of its wonders.

Newgrange was built around 3200 B.C. — hundreds of years before the Great Pyramid of Giza (2500 B.C.) and Stonehenge (3000 B.C.).

The massive hemispherical tomb is located in the Brú na Bóinne – Gaelic for the “palace” or “mansion” of the River Boyne. This 3-square mile area contains nearly a hundred ancient monuments, including two other large tombs, in addition, Newgrange, Knowth and Dowth.

A map of megalithic monuments in the Brú na Bóinne

Arriving at the iconic tomb is a wow-moment, to say the least. Standing outside the 80-meter mound, shored up with spiral-engraved kerbstones and topped with white Wicklow quartzite, a guide reveals the myths and history behind the monument.

Newgrange could have been designed as a tomb or a temple – in reality, nobody knows which. The truth will be shrouded in mystery forever.

Let there be light…

Once the scene has been set for you as a visitor, you’ll step inside the passage tomb itself, squeezing through standing stones carved with spiraling rock art and graffiti dating back to the 1800s (before Newgrange was taken into State care).

Ducking under beams of wood, you’ll emerge into the cool confines of a cruciform-shaped chamber like a stony igloo squirreled away within a hill.

This inner sanctum is where a lucky few (chosen by lottery from thousands of applicants annually) huddle together to witness the annual winter solstice illumination.

The illuminated inner corridor of Newgrange.

At this moment, when megalithic engineering and nature lock sensationally into sync, a shaft of light can be seen snaking 19 meters up the passageway, ultimately bathing the chamber in light. There are goosebumps, to say the least…

If you’re not one of the lucky ones, don’t fret. All visitors are treated to a simulated solstice, with an orange beam of light artificially showcasing the effect. It’s a tantalizing little taster – little wonder legend suggests that this was the site where mythological hero Cú Chulainn was Born.

Subterranean secrets…

Newgrange isn’t the only passage tomb in Ireland, of course. In fact, it’s not the only passage tomb at Brú na Bóinne. Together with nearby Knowth and Dowth, Newgrange has declared a Unesco World Heritage Site in 1993. Not bad for a site that once looked destined to become a quarry!

Not far away, near Oldcastle, County Meath, you’ll find a lesser-known cluster of passage tombs. Spotted around a handful of hills at Loughcrew are several cairns also dating from around 3,200BC. Because they’re more obscure and harder to get to, the Indiana Jones effect is all the more titillating.

If you get the sense that you’re being watched here, you may well be right. Some 60km away, atop of Slieve Gullian in County Armagh, the passage of another tomb points directly back towards Loughcrew.

Slieve Gullian’s two cairns lie on either side of a summit lake, with the southern tomb said to have a winter solstice alignment at sunset. On a good day, the views stretch as far as Dublin Bay.

Entire 18-acre Ancient Roman town discovered next to major motorway

Entire Ancient Roman Town Discovered Off A Highway In England

The site was found during the development of 124 new homes on an 18-acre plot near the A2 in Newington, Kent.

The remains of an entire ancient Roman town have been discovered close to a highway in southeast England.

Construction workers were preparing to build more than a hundred new houses when they came upon the nearly 2000-year-old ruins.

According to The Independent, a team of 30 archaeologists has spent 8 months excavating the site. They’ve found rare coins, pottery, and jewelry dating back to as early as 30 B.C., as well as the remains of an ancient temple.

The discovery of the 18-acre site off the A2 highway in Newington, Kent has proven to be a “massive” win in terms of contextualizing the region’s past.

“This is very exciting,” said Dean Coles, chairman of the Newington History Group. “The scale of this site, with the huge number and quality of finds, changes our knowledge of Newington’s development.”

Evidence of a 23-foot-wide road, sunken pottery kilns, and rare iron furnaces were also found at the site. Additionally, numerous costly items imported from other regions indicated that those who lived here at the time were of fairly high status.

Experts have called this find one of the most significant excavations in the region’s history. This remarkable discovery was made when housing developers were preparing to build 124 new homes.  In all corners of the world, it seems, building new tenements often unearths unexpected historical remnants and artifacts.

“We already had evidence of a Roman burial ground and Roman occupation in the immediate vicinity and this excavation shows there was a thriving manufacturing site in the heart of our village,” said Coles.

The current plan is to analyze the unearthed findings and collate all relevant data in a thorough scientific report. Once that is accomplished, experts will cover up the excavation site so the housing project can continue as planned. For now, though, the focus is on the amazing evidence that’s been found.

“The temple and major road are massive discoveries,” said Coles. “It proves the A2 wasn’t the only Roman road through the village.

As a group, we are keen to trace the route and destination of this new ‘highway’ which may have connected with another temple excavated 50 years ago on the outskirts of Newington and a village unearthed in 1882.”

In addition to pottery, jewelry, and a 23-foot-wide road, remains of an ancient temple were unearthed. Some of the items on the 18-acre site date to as early as 30 B.C.

With the Romans having taken over and occupied Britain for nearly 400 years after invading in 43 A.D., it’s no surprise that evidence of their time there remains scattered across the island. A significant portion of the 73-mile-long Hadrian’s Wall, for instance, still stands as a remnant of Ancient Rome.

Nonetheless, this new expansive, fruitful find has stunned archaeologists and historians alike.

“This is one of the most important discoveries of a Roman small town in Kent for many years with the preservation of Roman buildings and artifacts exceptional,” said Dr. Paul Wilkinson, archaeological director at Swale and Thames Archaeological Survey.

According to The Daily Mail, there’s much work ahead for the researchers involved. Finding the site, of course, was only the beginning. Archaeology project manager Peter Cichy, at least, is eager to commence the real work.

“This is one of the most significant sites in Kent but it’s only the beginning of months and months of work,” he said. “We will be analyzing and dating our finds, sorting and piecing together thousands of pottery shards, and writing up our report.”

As it stands, those waiting for their 124 new homes to finish construction may need to practice a little patience. One of the most valuable plots of Roman and British history has just been stumbled upon, after all — potentially holding answers to centuries-old questions of ancient life.

Remains of medieval child found with other skeletons just yards from St Patrick’s grave in Northern Ireland

Remains of a medieval child found with other skeletons just yards from St Patrick’s grave in Northern Ireland

Medieval skeletons were found beside Down Cathedral in Downpatrick

The medieval skeletons were found beside Down Cathedral in Downpatrick, County Down.

Archaeologists first thought they had found the lost cemetery of 13th Century Benedictine monks.

But they have said the oldest skeleton is that of a five or six-year-old child who died almost 1,000 years ago.

Archaeologist Brian Sloan believes there is “more to be found” in Downpatrick

The most recent skeleton is that of a young woman, believed to be a late adolescent, buried between 1317 and 1429.

Experts said she was suffering from severe tooth abscesses at the time of her death and believe she may have traveled to the on-site monastery in search of medicine or prayer.

A community dig was led by archaeologists from Queen’s University in Belfast, working with volunteers to prepare the ground for the erection of a replica high cross. Visitors from around the world flocked to the area as the dig unfolded.

‘Rich picture of medieval life’

Ancient pottery and animal bones were also recovered in the buried kitchen of a 13th Century Benedictine Abbey as well as a flint tool dating to about 7,000 BC.

Blackberry seeds, sloe pips, fish bones and charred wheat grains from bread-making were also found.

Medieval jugs found during the dig have been carefully pieced together

Excavation director Brian Sloan said subsequent analysis, including radiocarbon dating of three of the skeletons, had uncovered a “rich picture of medieval life”.

Although analysis of the skeletons is ongoing, he said evidence showed the young child had lived and died before the Anglo-Norman invasion of 1177 AD.

He said the young woman had lived sometime between 1317-1429 AD when the site was occupied by the Benedictine Abbey.

Mr. Sloan said the other archaeological finds had offered an insight into life in the abbey and a glimpse into an 8th Century Christian monastic site.

“We can use this evidence to build up a picture of the diet and everyday activities of the monks who lived and prayed here,” he added.

An arrow head from 12th or 13th Centuries is among other items found during the excavation

“The large pottery shards have been painstakingly pieced together at Queen’s University Belfast giving an idea of the shape, size, and decoration of the vessels.

“A rich environmental picture is being established through the processing of the soil samples taken during the excavation.”

Metalwork recovered from an ancient pit has also been analyzed and include fine copper alloy dress pins, a socketed arrowhead, a horseshoe, a pair of iron shears and a length of chain with a suspension hook still attached.

A number of items are now on display in the High Cross Gallery at Down County Museum in Downpatrick, in two new cases funded by the British Museum Trust, while research work continues on the collection of artifacts, dating from the Mesolithic (c. 7000 BC) period.

Mr. Sloan added: “This is fantastic as Downpatrick has almost been ignored from an archaeological and historical point of view. “It has got my blood flowing. I believe there is more to be found.”

The Irish Have Much More Viking DNA Than Previously Thought, Genetic Study Reveals

The Irish Have Much More Viking DNA Than Previously Thought, Genetic Study Reveals

An Irish Viking. The concept has become more real and more captivating. Anyone who’s read even a bit about the history of the Vikings knows that their DNA is likely to be found in people living in the British Isles today.

New research shows that the Irish definitely have their fair share of Viking heritage–in fact, the Irish are more genetically diverse than most people may assume.

The Irish have Viking and Norman ancestry in similar proportions to the English. A comprehensive DNA map of the Irish has for the first time revealed lasting contributions from British, Scandinavian, and French invasions.

“By comparing 1,000 Irish genomes with over 6,000 genomes from Britain and mainland Europe, genetic clusters within the west of Ireland, in particular, were discovered for the first time, leading the researchers to investigate if invasions from the Vikings and Normans to the east may have influenced genetics in that part of the country,” according to Irish Central.

Because of extensive Irish immigration to the United States and other countries, these findings have ramifications. There are 80 million people in the world who claim Irish heritage.

 “This subtle genetic structure within such a small country has implications for medical genetic association studies,” said Trinity College Dublin geneticist Dr. Ross Byrne. In fact a number of American slang words have roots coming from the Irish:

Researchers found 23 distinct genetic clusters, separated by geography by comparing mutations from almost 1,000 Irish genomes with over 6,000 from Britain and mainland Europe.

“These are most distinct in western Ireland, but less pronounced in the east, where historical migrations have erased the genetic variations,” said the Irish Mirror.

The researchers studied genes from Europe and calculated the timing of the historical migrations of the Norse-Vikings and the Anglo-Normans to Ireland, yielding dates consistent with historical records.

The Vikings invaded Ireland for the first time in the 8th century, raiding a monastery on Rathlin Island on the northeast coast. The Viking warriors were large in numbers and well armed.

They moved inland along river-ways, attacking the monastic settlements they came across. They also took captives to trade as slaves.

The Vikings in Ireland built wintering camps, known as longphorts (derived from the Irish words boat & fort), a ship port. This meant they could settle on the island longer. They used their longphorts as a base allowing them to perform further in-land raids.

Although longphorts were mainly built to only last one winter, some of them became major settlements, such as the one in Dublin, Dyflinn, founded in 841 AD.  Excavations during the 1970’s discovered more than 100 homes from this early period and thousands of daily household objects in Dublin.

The Viking conquest in Ireland would continue for more than 200 years, until the arrival of the Anglo-Normans. In the late 12th century, the Norman lords who had already subjugated England came to Ireland to take large plots of land. In the 16th century, under Elizabeth I, many more English Protestant families arrived, often displacing the native Catholics.

It’s believed that the first group of Vikings to invade Ireland were from Scandinavia. They had also settled in Scotland and would later become known as Gallowglass, an elite mercenary warrior group. From the mid-13th to the early 17th centuries they fought for hire in Ireland itself. Their name is an Anglicization of the Gaelic word gallóglach (roughly pronounced GAHL-o-glukh), which translates as “foreign warrior.”

Gallowglass are descendants of not only Vikings but of Scots native to the western Highlands and Hebrides. As Scottish historian Fergus Cannan notes, the Gallowglass “lived for the war.…His sole function was to fight, and his only contribution to society was destruction.”

Skeleton of man who had his throat slit by Anglo Saxon executioners 1,000 years ago is uncovered during excavations for a new wind farm

Skeleton of man who had his throat slit by Anglo Saxon executioners 1,000 years ago is uncovered during excavations for a new wind farm.

During the excavation job for a wind farm, remains of a Man believed to be the victim of an execution that killed 1,000 years ago were discovered.

During a dig in preparing for the Rampion Offshore Wind Farm, archeologists discovered the adult guy, aged between 25 and 35, with deadly cut marks on his throat.

The skeleton was recovered intact with the exception of a few small bones missing from the hands and feet.

He was laid facing upwards with his arms at his side in an East-West alignment, with no sign of a coffin.

The remains were found during surveying work for the route for onshore cabling on the South Downs at Truleigh Hill, north of Shoreham-by-Sea, West Sussex

Jim Stevenson, project manager for Archaeology South East, said:

“Specialist osteological assessment and radiocarbon dating have revealed that the skeleton is most likely to be an execution burial of the later Anglo Saxon period of around 1010 to 1025 AD.

“Most significantly, two cut marks made by a sharp blade or knife were found at the mid-length of the neck, which would have proved fatal for the individual.”

The skeleton was found during work for a wind farm 

The isolated burial was found along the ancient route of the South Downs Way in an area of known prehistoric graves recorded in the West Sussex Historic Environment Record.

It is believed some were once identifiable as visible surface burial mounds, were excavated in the 18th and 19th centuries and sometimes coincide with isolated burials.

The Rampion Offshore Wind Farm, 13km off the Sussex coast, is due to be fully operational later this year.

Once complete, it will provide enough electricity to supply almost 347,000 homes a year, equivalent to about half the homes in Sussex.

A pair of golden sandals found in King Tutankhamun’s tomb that shows how Egyptian sandals were made

A pair of golden sandals found in King Tutankhamun’s tomb that shows how Egyptian sandals were made

During the ancient Egyptian period, people mostly traveled barefoot. It is believed that since the temperature in Egypt was very high throughout the year, people gave less importance to wearing footwear.

There is hardly any record to suggest that the Egyptians wore shoes or any other form of footwear.

The ancient Egyptians began wearing sandals during the early years of the New Kingdom rule.

The sandals used by these people were very simple and were made either by using straw, reeds or leather.

The wealthy people wore leather sandals and these lasted for a longer time than the sandals which were made using straw or reeds. The sandals were worn by all people belonging to all the classes except those who were extremely poor. 

The sandals were decorated by using beads, jewels; some also had buckles on the straps made from precious metals. For the most part, the ancient Egyptians walked without wearing sandals or shoes.

Sandals were worn by people on special events. The gold and wood sandals are known to have been made in the ancient Egyptian period.

For researchers, the wow-factor is in the craftsmanship. “The technology employed that’s the most wow thing for us, looking at the detailed, minute, skilled craftsmanship of the Ancient Egyptians is really mind-blowing,” Ikram explained.

“With some of Tutankhamun’s shoes, they used bits of gold, birch bark, bone and maybe even glass inlays to decorate and create luxurious and glamorous footwear.”

Studying how the Egyptians made such luxurious footwear, researchers discovered that the ancient Egyptians adapted and maintained traditional styles and technologies throughout millennia.

“It’s interesting to see that there are not too many advances in the technology, but we do see things that were established and then carried on,” Ikram noted. “For example, there’s skeuomorphism, that is something originally made in one material is translated into something of far more precious material.

Sometimes you have fancy footwear that looks like regular footwear, but it’s made out of gold or it has gold accents.”

During the Middle and New Kingdoms time, the sandals were commonly used. The use of covered shoes by the ancient Egyptians is not very well known. However, some records suggest that shoes were made by weaving palm fiber and grass.

In the Early Middle Kingdom, shoes were a modification of sandals. Shoes had straps between the toes and were joined to the sides at the heel. It also had a leather cover which protected the feet.

The Hittites settled in Anatolian highlands wore shoes with turned up toes. The Egyptians during the New Kingdom period are said to be influenced by the Hittites and began using shoes.

Decorated Medieval Leather Found in Northern England

Decorated Medieval Leather Found in Northern England

ENGINEERS from Northern Powergrid have unearthed a highly decorated fragment of leather in York, thought to be from medieval times.
ENGINEERS from Northern Powergrid have unearthed a highly decorated fragment of leather in York, thought to be from medieval times.

The artifact, which features a dragon or other mythical beast design, was discovered on Aldwark as part of the electrical distribution firm’s £300,000 investment in York’s power network.

Mike Hammond, Northern Powergrid’s general manager for the North Yorkshire region, said: “To find a piece of York’s past as we invest in the city’s future is really exciting.

“We’ve been working closely with the York Archaeological Trust as part of our work to replace high voltage cable on Aldwark, Goodramgate, and Deansgate.

The first scheme of work to improve the reliability and resilience of the electricity network but were not expecting to unearth anything quite so interesting.

We are working with the York Archaeological Trust to ensure the restoration and conservation of the leather fragment, which looks like it could be straight out of Game of Thrones, with its medieval dragon design.”

Northern Powergrid has completed the first of four schemes in York two weeks ahead of schedule, which will see some two-and-a-half kilometers of high voltage underground cable replaced across the city center during 2018/19.

The second scheme of work, which will take place on Grosvenor Road, Bootham Crescent and Queen Anne’s Road, has been brought forward and started on Monday ahead of schedule.

Toby Kendall, project officer from York Archaeological Trust, added: “Good early communication with the team from Northern Powergrid and the contractors completing the excavations has allowed us to archaeologically monitor and record the works without causing any delays.

The incredibly well preserved, and fantastically decorated, leather fragment had probably been disturbed from its waterlogged, deeper, burial conditions when the sewers were first installed over 100 years ago.

The recovery of the artifact shows the value of observing the works underway, even though they have not directly disturbed the waterlogged archaeology lower down.”
