OU archaeologists uncover buried building in the ancient Mexican city

OU archaeologists uncover buried building in the ancient Mexican city

University of Oklahoma researchers have made a finding that they believe could change the world’s view of an ancient capital.

The location of a buried building under the surface of the Main Plaza at Monte Alban, one of the first towns to establish in all of pre-Hispanic Mexico, was recently found by archaeologists from the University of Oklahoma.

The team used ground-penetrating radar, electrical resistance, and gradiometry to locate the structure.

“This discovery changes our understanding of the history of the Main Plaza and how it was organized and used,” said Marc Levine, assistant curator of archaeology at the Sam Noble Oklahoma Museum of Natural History and assistant professor in the Department of Anthropology, College of Arts and Sciences. “Everything is deeply symbolic here.”

The building appears to resemble stone temples that were excavated by Mexican archaeologists in the 1930s.

Evidence from those temples indicates they were used for religious practices like burning incense, making offerings and ritual bloodletting.

Monte Albán was established in 500 BCE and eventually grew to become a powerful regional capital with impressive buildings featuring carved stone monuments with a highly developed artistic style and written language.

The Main Plaza was built, expanded and remodelled over 1,000 years before the site’s collapse around 850 CE.

Archaeologists have investigated many of the buildings erected around the Main Plaza, but have never focused research on the plaza itself to better examine its role in society.

OU researchers hope to develop a clearer picture of what the Main Plaza looked like during its early history and better appreciate the amount of work that went into its construction.

“If you think of the National Mall in Washington, D.C., every monument and every building that goes on that mall has a significance and was thought over, carefully planned and oriented in a certain way,” Levine said. “The same goes for Monte Albán.”

Levine stresses the importance of the site, saying the Main Plaza is even featured on the country’s 20 peso note.

The OU team also used a drone to create a digital map of the Main Plaza and its associated structures. With the help of a supercomputer, the team is creating 3-D images of all the buildings to measure their volume.

This will provide a better understanding of the effort required to move all the dirt and construct the buildings. Levine estimates the team will spend about two years analyzing all of their data to complete their study of the plaza.

“We may find some other things that are important that we haven’t had a chance to process yet,” he added.

Thousand-Year-Old Goblet Shows Ancient Romans Used Nanotechnology

Thousand-Year-Old Goblet Shows Ancient Romans Used Nanotechnology

Finally, researchers have discovered why the jade-green cup appears red when lit from behind. The colourful secret of a 1,600-year-old Roman chalice at the British Museum is the key to a super­sensitive new technology that might help diagnose human disease or pinpoint biohazards at security checkpoints.

Thousand-Year-Old Goblet Shows Ancient Romans Used Nanotechnology
The Romans may have first come across the colourful potential of nanoparticles by accident, but they seem to have perfected it.

When lit from the front, the glass chalice, known as the Lycurgus Cup because it bears a scene involving  King Lycurgus of Thrace, appears jade green when lit from the front but blood-red when lit from behind—a property that puzzled scientists for decades after the museum acquired the cup in the 1950s.

The mystery wasn’t solved until 1990 when researchers in England scrutinized broken fragments under a microscope and discovered that the Roman artisans were nanotechnology pioneers: They’d impregnated the glass with particles of silver and gold, ground down until they were as small as 50 nanometers in diameter, less than one-thousandth the size of a grain of table salt.

The exact mixture of the precious metals suggests the Romans knew what they were doing—“an amazing feat,” says one of the researchers, archaeologist Ian Freestone of University College London.

The ancient nanotech works something like this: When hit with light, electrons belonging to the metal flecks vibrate in ways that alter the colour depending on the observer’s position.

Gang Logan Liu, an engineer at the University of Illinois at Urbana-Champaign, who has long focused on using nanotechnology to diagnose disease, and his colleagues realized that this effect offered untapped potential.

“The Romans knew how to make and use nanoparticles for beautiful art,” Liu says. “We wanted to see if this could have scientific applications.”

When various fluids filled the cup, Liu suspected, they would change how the vibrating electrons in the glass interacted, and thus the colour. (Today’s home pregnancy tests exploit a separate nano-based phenomenon to turn a white line pink.)

Since the researchers couldn’t put liquid into the precious artefact itself, they instead imprinted billions of tiny wells onto a plastic plate about the size of a postage stamp and sprayed the wells with gold or silver nanoparticles, essentially creating an array with billions of ultra-miniature Lycurgus Cups.

When water, oil, sugar solutions and salt solutions were poured into the wells, they displayed a range of easy-to-distinguish colours—light green for water and red for oil, for example.

The proto­type was 100 times more sensitive to altered levels of salt in solution than current commercial sensors using similar techniques.

It may one day make its way into handheld devices for detecting pathogens in samples of saliva or urine, or for thwarting terrorists trying to carry dangerous liquids onto airplanes.

The original fourth-century A.D. Lycurgus Cup, probably taken out only for special occasions, depicts King Lycurgus ensnared in a tangle of grapevines, presumably for evil acts committed against Dionysus, the Greek god of wine.

If inventors manage to develop a new detection tool from this ancient technology, it’ll be Lycurgus’ turn to do the ensnaring.

9,000-Year-Old Stonehenge-Like Structure Found Under Lake Michigan

9,000-Year-Old Stonehenge-Like Structure Found Under Lake Michigan

Archaeologists found something much more fascinating than they got credit for when searching under the waters of Lake Michigan for shipwrecks: they uncovered a rock with a prehistoric carving of a mastodon, as well as a collection of stones arranged in a Stonehenge-like manner.

Gazing into the water

In modern archaeology, the use of remote sensing techniques is common: scientists regularly survey lakes and soil for hidden objects.

Archaeologists uncovered sunken boats and cars and even a Civil War-era pier at a depth of around 40 feet into Lake Michigan’s Grand Traverse Bay, using sonar techniques to search for shipwrecks,  but among all these, they found this prehistoric surprise, which a trained eye can guess by looking at the sonar scans photos in this article.

“When you see it in the water, you’re tempted to say this is absolutely real,” said Mark Holley, a professor of underwater archaeology at Northwestern Michigan University College who made the discovery, during a news conference with photos of the boulder on display in 2007. “But that’s what we need the experts to come in and verify.

Professor Mark Holley hopes that a computer model of the carving in the mastodon rock will help petroglyph experts

The boulder with the markings is 3.5 to 4 feet high and about 5 feet long. Photos show a surface with numerous fissures.

Some may be natural while others appear of human origin, but those forming what could be the petroglyph stood out, Holley said.

Viewed together, they suggest the outlines of a mastodon-like back, hump, head, trunk, tusk, triangular-shaped ear and parts of legs, he said.

“We couldn’t believe what we were looking at,” said Greg MacMaster, president of the underwater preserve council.

Specialists shown pictures of the boulder holding the mastodon markings have asked for more evidence before confirming the markings are an ancient petroglyph, said Holley.

“They want to actually see it,” he said. Unfortunately, he added, “Experts in petroglyphs generally don’t dive, so we’re running into a little bit of a stumbling block there.”

If found to be true, the wannabe petroglyph could be as much as 10,000 years old – coincident with the post-Ice Age presence of both humans and mastodons in the upper midwest.

The stones of discovered underwater structure are organised circle and believe to be at least 10,000 years old.

The formation, if authenticated, wouldn’t be completely out of place. Stone circles and other petroglyph sites are located in the area.

The discovery was made back a few years ago, and surprisingly enough the find hasn’t been popularized at all, with little to no information available online, but I’ll be sure to update this post as soon as I can get ahold of more info.

3000-year-old temple-era gold bead found by 9-year-old Jerusalem boy

3000-year-old temple-era gold bead found by 9-year-old Jerusalem boy

A nine-year-old boy, the Temple Mount Sifting Project (TMSP) revealed earlier this week, found the first-ever Temple-era gold granule bead during wet sifting of earth from the Temple Mount.

In August, while sifting through the soil with his kin, Binyamin Milt, a resident of Jerusalem, unearthed a perfectly preserved small, flower-shaped cylinder, made of four layers of tiny gold balls, unaware that the item he carried was probably forged around 3,000 years ago.

In fact, the bead was so well preserved that when the boy took the bead to the supervising archaeologist, he initially wrote it off as likely to be an unidentified modern object, not even writing down the boy’s contact information before hurrying back to continue sifting.

First Temple-era gold granule bead

It was only while sorting through the summer’s artefacts in Dr Gabriel Barkay’s backyard that he realized the bead was strikingly similar to several similar items he had found when he excavated burial systems from the First Temple period in Katef Hinnom.

While those beads were made of silver, they were identical to the gold bead in both shape and manufacturing method (called granulation).

Similar beads have been found in several other sites across Israel, dated to various periods, with the overwhelming majority dating to the Iron Age (12th to 6th centuries BCE).

Once the bead’s significance had become clear, TMSP researchers called all the families who participated in the sifting on that specific day, until they made contact with Binyamin.

Pieces of gold jewellery are rarely found among archaeological artefacts from the First Temple period since gold at that time was not refined and generally contained a significant percentage of silver.

Granulation is a technique which demands of the goldsmith a considerable amount of expertise and experience, due to the many components and complex manufacturing stages.

The granules are shaped using tiny metal pieces which are melted on a bed of charcoal or charcoal powder, which absorbs air, preventing oxidation.

Once the metal melts, the surface tension of the liquid produces ball-shaped drops. An alternative method involves dripping the liquid metal from a height into a bowl and constantly stirring the drops.

At this stage, it is not yet clear what purpose the bead served, though initial projections by TMSP members say it could have been part of an ornament worn by an important personage who visited the Temple, or by a priest. More info on the piece will be published once all the artefacts from the summer are processed.

TMSP was founded in response to illegal renovations which were carried out in 1999 by the northern branch of the Islamic Movement, disposing of over 9,000 tons of dirt, mixed with invaluable archaeological artefacts, dumping it all into the Kidron Valley.

Archaeologists Dr Gabriel Barkay and Zachi Dvira retrieved the rubble and began sifting through it in 2004, with the goal of understanding the archaeology and history of the Temple Mount, while preserving history.

Over the years, it has grown into an internationally significant project, bringing in over 200,000 volunteers who have helped the researchers find thousands of priceless artefacts.

Norway ice melt reveals ‘frozen archive’ of ancient reindeer-hunting arrows

Norway ice melt reveals ‘frozen archive’ of ancient reindeer-hunting arrows

In the Jotunheimen Mountains, the team found 68 arrows on the Langfonne ice patch, tracing the objects again to various lengths of time over 1000 years, from the Stone Age to the Medieval Period.

In addition, the find, printed this week as an examination in the Holocene journal, includes the stays of reindeer antlers, Iron Age scaring sticks utilised in reindeer searching and a 3,300-year-old shoe from the Bronze Age.

In line with the authors of the survey, the arrows mark the earliest ice findings in Northern Europe.

Norway ice melt reveals 'frozen archive' of ancient reindeer-hunting arrows
Archaeologists have uncovered a haul of ancient artifacts from a melted ice patch in Norway, including this leather boot that dates back more than 3000 years.

Norway’s Jotunheimen Mountains are positioned greater than 200 miles (in extra of 320 kilometres) north of the capital, Oslo.

The Langfonne ice patch, the place the arrows have been discovered, has retreated by greater than 70% over the previous 20 years as international warming has brought about dramatic ice melt, the examine says.

“With the ice now retreating due to climate change, the evidence for ancient hunting at Langfonne is reappearing from what is, in essence, a frozen archive,” mentioned Lars Pilø, the examine’s lead writer and an archaeologist from the Innlandet County Council, in a press release.

“The ice melt, sad as it is, provides an unprecedented archaeological opportunity for new knowledge.”

The oldest arrows, courting again to 4000 BC, are in a poor situation. But surprisingly, the arrows from the Late Neolithic interval (2400-1750 BC) have been higher preserved compared to these from the next 2,000 years, in line with the examine.

Researchers discovered a plethora of ancient arrows that date across various periods of Norwegian history.

Using floor penetrating radar (GPR) know-how, researchers imagine that the dangerous state of the oldest arrows could also be as a result of ice motion.

GPR information revealed ice deformation deep inside of the patch could have damaged the outdated, brittle arrows, however, it additionally helped to convey them to the floor to be found.

“Icy patches are not your regular archaeological sites,” Pilø mentioned. “Glacial archaeology has the potential to transform our understanding of human activity in the high mountains and beyond.”

Thailand: Rare 5,000 Years old whale skeleton discovered

Thailand: Rare 5,000 Years old whale skeleton discovered

In Samut Sakhon, researchers say, an almost fully preserved whale skeleton believed to be between 3,000 and 5,000 years old has been uncovered.

Thailand: Rare 5,000 Years old whale skeleton discovered
The rare whale skeleton discovered in Thailand. It is thought to be up to 5,000 years old.

The bones were discovered about 12 kilometres from the coast in the province just west of Bangkok in early November, the BBC announced on Friday.

The 12-metre-long skeleton is thought to be that of a Bryde’s whale, it said.

Experts hope the find might provide “a window into the past”, especially for research on sea levels and biodiversity.

The partially fossilised bones are “a rare find”, mammal researcher Marcus Chua of the National University of Singapore told the BBC.

“There are few whale subfossils in Asia,” he said, and even fewer ones are “in such good condition”.

Pictures shared by Environment Minister Varawut Silpa-Archa show the bones apparently almost entirely intact.

According to Mr Varawut, more than 80% of the skeleton has so far been recovered, including vertebrae, ribs, fins and one shoulder blade.

The skeleton’s head alone is estimated to be about 3 metres in length.

Mr Chua said the discovery would allow researchers to find out more about the particular species in the past, whether there were any differences compared to today’s Bryde’s whales.

The skeleton will also provide information about the “paleobiological and geological conditions at that time, including sea level estimation, types of sediments, and the contemporary biological communities at that time”.

“So this find provides a window into the past once the skeleton has been dated,” Mr Chua said.

The bones are yet to be carbon-dated to determine their exact age, with the results expected in December.

The Gulf of Thailand has an interesting history in the last 10,000 years, Mr Chua pointed out, with sea levels possibly up to four metres higher than today and active tectonic activity.

Bryde’s whales, which live worldwide in warm temperate and tropical waters, are still found in the waters around Thailand today.

3,300-Year-Old Tomb with Pyramid Entrance Discovered in Egypt

3,300-Year-Old Tomb with Pyramid Entrance Discovered in Egypt

Archaeologists believe a tomb recently excavated at an ancient cemetery in Egypt would have boasted a pyramid 7 metres (23 feet) high at its entrance.

Dating back around 3,300 years this tomb was discovered recently at an ancient cemetery at Abydos in Egypt. At left the rectangular entrance shaft with massive walls served as a base for a small pyramid that was an estimated 23 feet (7 meters) high.

Found on the site of Abydos, the tomb dates back some 3,300 years. A team of archaeologists discovered a finely carved sandstone sarcophagus, painted red inside one of its vaulted burial chambers, which was created for a scribe named Horemheb. The sarcophagus has images of several Egyptian gods on it and hieroglyphic inscriptions recording spells from the Book of the Dead that helped one enter the afterlife.

There is no mummy in the sarcophagus, and the tomb was ransacked at least twice in antiquity. Human remains survived the ransacking, however. Archaeologists found disarticulated skeletal remains from three to four men, 10 to 12 women and at least two children in the tomb.

The chambers that the archaeologists uncovered would have originally resided beneath the surface, leaving only the steep-sided pyramid visible.

“Originally, all you probably would have seen would have been the pyramid and maybe a little wall around the structure just to enclose everything,” said Kevin Cahail, a doctoral student at the University of Pennsylvania, who led excavations at the tomb.

In one of the burial chambers, the archaeologists found a sandstone sarcophagus, painted red, which was created for a “scribe” named Horemheb.

The pyramid itself “probably would have had a small mortuary chapel inside of it that may have held a statue or a stela giving the names and titles of the individuals buried underneath,” Cahail told Live Science, all that remains of the pyramid are the thick walls of the tomb entranceway that would have formed the base of the pyramid. The other parts of the pyramid either haven’t survived or have not yet been found. 

Military ties

It was not uncommon, at this time, for tombs of elite individuals to contain small pyramids, Cahail said. The tomb was excavated in the summer and winter field seasons and Cahail will be presenting results at the annual meeting of the American Research Center in Egypt, to be held in Portland.

Cahail believes that Horemheb’s family had military ties that allowed them to afford such an elaborate tomb. Another burial chamber, this one missing a sarcophagus, contains shabti figurines that were crafted to do the work of the deceased in the afterlife. Writing on the figurines say that they are for the “Overseer of the Stable, Ramesu (also spelled Ramesses).” This appears to be a military title and it’s possible that Ramesu was the father or older brother of Horemheb, Cahail said.

He noted it’s interesting that both Horemheb and Ramesu share names with two military leaders, who lived at the same time they did. Both of these leaders would become pharaohs.

“They could actually be emulating their names on these very powerful individuals that eventually became pharaoh, or they could have just been names that were common at the time,” Cahail said.

Multiple wives?

The bones the team discovered in the tomb indicate that considerably more women than men were buried in the tomb. This brings up the question of whether Horemheb and Ramesu had multiple wives at the same time. Cahail said that polygamy was a common practice among the pharaohs, but it’s uncertain if it was practised among non-royalty.

Another possibility is that the tomb was used for multiple generations by the same family and contains the remains of daughters, mothers and other female relatives. Yet another possibility is that the tomb was re-used, without permission, at a later date.

Radiocarbon tests, which can provide a date range for the bones, may be done in the future to help solve the mystery.

“You’re left with the question, who are all these people?” Cahail said.

A Jasper treasure

One of the most interesting artefacts the team found was a heart amulet, made of red and green jasper. The hard stone amulet was broken into three pieces.

“It’s a beautiful object and possibly one of the best-carved examples of these very rare type of amulets,” Cahail said. “It was probably on the chest of one of the deceased individuals and there probably would have been some sort of necklaces and gold and things like that.”

The purpose of this heart-shaped amulet was probably related to spells from the Book of the Dead that tell the heart of the deceased not to lie. The ancient Egyptians believed that, after death, their hearts would be put on a scale and weighed against a feather representing ma’at, an Egyptian concept that includes truth and justice. If their heart weighed the same or less they could obtain eternal life, but if it weighed more they were destroyed.

“Essentially, your heart and your good deeds and everything that you’ve done in your life are weighed against the measure of truth,” Cahail said.

The impressive Roman military base found in Cornfield in Serbia

The impressive Roman military base found in Cornfield in Serbia

The well-maintained ruins of the headquarters of a Roman legion, hidden under a Serbian cornfield near the coal mines, are excavated by archaeologists, who say that its rural location makes it exceptional.

Covering an estimated 3,500 square meters, the headquarters – or principium – belonged to the VII Claudia Legion. Its location was deduced in the spring during a survey.

There are over 100 recorded principiums across the territory of the Roman empire, but almost all are buried under modern cities, said Miomir Korac, lead archaeologist of digs there and at the Roman provincial capital Viminacium that the compound served.

Miomir Korac, the lead archaeologist, poses for a picture at the remains of Roman legion’s headquarters at the ancient city of Viminacium, near Kostolac, Serbia.

“A very small number of principiums are explored completely (and) … so we can say (preservation of) this one is unique as it is undisturbed.”

The compound, which lies east of Belgrade and around one metre (3 ft) under the surface, had 40 rooms with heated walls, a treasury, a shrine, parade grounds and a fountain.

So far only a quarter has been explored, with excavations scheduled to resume next spring.

Inside one room, archaeologists found 120 silver coins that “must have been lost during an emergency” such as an invasion or a natural disaster, said the principium’s lead archaeologist Nemanja Mrdjic.

Buried under a Serbian cornfield, Roman military headquarters slowly sheds its secrets

“The distribution of coins from a corner to the door, … suggests they (coins) spilled while someone was fleeing.”

The VII Claudia Legion was active between 2nd and 5th centuries AD, and its walled camp and principium were separated from the rest of Viminacium, which had its own fortifications.

Excavations of Viminacium have been ongoing since 1882 and finds there include a Roman ship, golden tiles, jade sculptures, mosaics and frescos, along with 14,000 tombs and the remains of three mammoths.

Archaeologists estimate that they have only uncovered 4% of the site, which they say it’s bigger than New York’s Central Park.
