7,000-Year-Old Native American ‘Bog Burial’ Found Off the Coast of Florida

7,000-Year-Old Native American ‘Bog Burial’ Found Off the Coast of Florida

The 167 bodies discovered in a pond in Windover, Florida started to stir up excitement in the archaeological world only after the bones were declared very old, and not the product of mass murder. Researchers from Florida State University came to the site, believing that in the swampland some more Native American bones had been found.

They believed the bones were between 500 and 600 years old. But then the bones were dated with radiocarbon. It turns out that these corpses were between 6,990 and 8,120 years old. The academic community was then incredibly excited. Windover Bog has proved to be one of the United States’ most significant archaeological discoveries.

In 1982, Steve Vanderjagt, the man who made the discovery, was using a backhoe to demolish the pond to create a new subdivision between Disney World and Cape Canaveral. A large number of rocks in the pond confused Vanderjagt since the region of Florida was not considered to be particularly rocky.

Getting out of his backhoe, Vanderjagt went to investigate and almost immediately realized that he had unearthed a huge pile of bones. He called the authorities right away. It was only thanks to his natural curiosity that the site was preserved. After the medical examiners declared them ancient, the specialists from Florida State University were summoned (another brilliant move by Vanderjagt- too often sites are ruined because experts are not called).

The pond that Steve stumbled upon.

Deeply intrigued, EKS Corporation, the developers of the site, financed the radiocarbon dating. Once the striking dates were revealed, the State of Florida providing a grant for the excavation.

Unlike the human remains found in European bogs, the Florida bodies are only skeletons – no flesh remains on the bones. But this does not negate their significance. Nearly half of the skulls contained brain matter. The majority of the skeletons were found lying on their left sides with their heads pointing westward, perhaps toward the setting sun, and their faces pointing to the north.

Most had their legs tucked up, as in the fetal position, however, three were lying straight. Interestingly, each corpse had a stake thrust through the loose fabric that enshrouded them, presumably to prevent them from floating to the surface of the water as decomposition filled them with air. This practical step was what ultimately protected the bodies from scavengers (animals and grave robbers) and kept them in their intended positions.

The find provides unparalleled insight into a hunter-gather community that existed 3,500 years before the Pyramids were built in Egypt. The skeletons and the artefacts found with them have been studied almost continuously in the decades since their discovery.

People Digging.

The research paints a picture of a hard but good life in pre-Columbian Florida. Though living mainly off what they could hunt and gather, the community was sedentary, indicating that whatever hardships they may have faced were small compared with the benefits of the area they chose to settle in.

Theirs was an incredibly caring society. Children’s bodies were almost all found to have small toys in their arms. One older woman, perhaps 50, showed signs of having several broken bones. The fractures occurred several years before her death, meaning that despite her handicap the other villagers cared for her and helped her even when she could no longer contribute significantly to the workload.

Another body, that of a 15-year-old boy, showed that he was a victim of spina bifida, a crippling birth defect where the vertebrae do not grow together properly around the spinal cord. Despite his many deformed bones, evidence suggests he was loved and cared for throughout his life. These discoveries are mind-boggling when one considers how many ancient (and even a few modern) societies abandon the weak and deformed.

Contents found within the corpses’ as well as other organic remains found in the bog reveal an ecosystem rich in diversity. 30 species of edible and/or medicinal plants were identified by paleobotanists; berries and small fruits were particularly important to the community’s diet.

One woman, perhaps 35 years old, was found with a concoction of elderberry, nightshade, and holly in the area where her stomach would have been, suggesting that she was eating medicinal herbs to try and combat an illness.

Unfortunately, the combination did not work and whatever afflicted the woman ultimately took her life. Interestingly, the elderberry woman was one of the few bodies stretched out, as opposed to curled up, with her face pointing downward. In other Native American traditions, elderberries were used to fight viral infections.

Archaeological site.

Another striking difference between the Windover Bog people and their European counterparts is that none of the Floridians suffered violent deaths. The bodies include men, women, and children.

Roughly half of the bodies were younger than 20 years old when they died but some were well over 70 years old. This was a fairly good mortality rate for the place and time.

The presence of brain matter in 91 of the bodies suggests that they were buried quickly, within 48 hours of death. Scientists know this because, given the hot humid climate of Florida, brains would have liquefied in bodies not buried quickly.

Somewhat amazingly, DNA analysis of the remains shows that these bodies share no biological affiliation with the more modern Native American groups known to have lived in the area.

Recognizing the limitations of modern technology, about half of the Windover site was left intact, as a protected National Historic Landmark, so that in 50 or 100 years’ researchers could return to the bog and excavate untouched remains.

Archaeologists uncover lost Indigenous NE Florida settlement of Sarabay

Archaeologists uncover lost Indigenous NE Florida settlement of Sarabay

The University of North Florida archaeology team is now fairly confident they have located the lost Indigenous northeast Florida community of Sarabay, a settlement mentioned in both French and Spanish documents dating to the 1560s but had not been discovered until now.

The type and amounts of Indigenous pottery the team is finding combined with the type and dates for European artefacts as well as cartographic map evidence strongly supports this location as the late 16th/early 17th century Mocama settlement.

The researchers have opened large excavation blocks with many exciting new artefacts finds and are currently searching for evidence of houses and public architecture.

UNF Archaeology Lab at the dig site.

The students, led by Dr. Keith Ashley, UNF Archaeology Lab director and assistant professor, have recently recovered more than 50 pieces of early Spanish pottery as well as Indigenous pottery that dates to the late 1500s or early 1600s.

They have also recovered bone, stone and shell artefacts as well as burned corn cob fragments.

Expanding upon UNF excavations conducted at the southern end of Big Talbot Island in 1998, 1999, and 2020, the UNF research team has completed what is likely the most extensive excavations at a Mocama-Timucua site in northeastern Florida history.

This dig is part of the UNF Archaeology Lab’s ongoing Mocama Archaeological Project. This study focuses on the Mocama-speaking Timucua Indians who lived along the Atlantic coast of northern Florida at the time of European arrival in 1562.

The Mocama were among the first indigenous populations encountered by European explorers in the 1560s.

The team hopes to ultimately confirm the discovery of Sarabay by finding evidence of houses and public architecture.

They will continue to explore and learn about Sarabay’s physical layout during continuing fieldwork projects over the next three years.

9,000-Year-Old Obsidian Tools Found at Bottom of Lake Huron

Obsidian, or volcanic glass, is a prized raw material for knappers, both ancient and modern, with its lustrous appearance, predictable flaking, and resulting razor-sharp edges.

As such, it was used and traded widely throughout much of human history. Obsidian from the Rocky Mountains and the West was an exotic exchange commodity in Eastern North America.

“Obsidian from the far western United States is rarely found in the east,” said Dr Ashley Lemke, an anthropologist in the Department of Sociology and Anthropology at the University of Texas at Arlington.

The two ancient obsidian artefacts were recovered from a sample of sediment that was hand excavated at a depth of 32 m (105 feet) in an area between two submerged hunting structures at the bottom of Lake Huron.

“This particular find is really exciting because it shows how important underwater archaeology is,” Dr. Lemke said.

“The preservation of ancient underwater sites is unparalleled on land, and these places have given us a great opportunity to learn more about past peoples.”

The larger artifact is a mostly complete, roughly triangular, biface thinning flake made from black and translucent material with a sub-vitreous texture.

The second artefact is a small, very thin, translucent flake on a material visually similar to the larger specimen.

“These tiny obsidian artefacts reveal social connections across North America 9,000 years ago,” Dr. Lemke said.

“The artifacts found below the Great Lakes come from a geological source in Oregon, 4,000 km (2,485 miles) away — making it one of the longest distances recorded for obsidian artifacts anywhere in the world.”

The findings were published in the journal PLoS ONE.

Is this the rock that proves Vikings did discover America?

Is this the rock that proves Vikings did discover America?

They are infamous for terrorising the coastlines of Europe in their distinctive longships, but the Vikings may be able to claim another victory over their medieval neighbours. New evidence has been uncovered that suggests the Vikings may have discovered North America nearly 500 years before Christopher Columbus made his famous journey to the New World. Scientists claim to have uncovered what they believe to be a Viking settlement on the Canadian island of Newfoundland that appears to have been built between 800AD and 1300AD.

Is this the rock that proves Vikings did discover America?
New evidence of a Viking settlement in North America has been unearthed in Newfoundland (a hearth where iron ore appears to have been roasted is pictured) which suggests the Scandinavians were the first Europeans to set foot in the New World around 500 years before Christopher Columbus

It is only the second known Viking site to be discovered in North America and helps to confirm that they were the first Europeans to reach the New World. This new site, discovered in an area called Point Rosee in southern Newfoundland, is 400 miles (643km) south west of a Viking settlement found in L’Anse aux Meadows during the 1960s. Archaeologists said the discovery potentially opens ‘a new chapter’ in history by showing the Vikings had explored far further into the New World than previously believed possible.

Dr Sarah Parcak, an archaeologist at the University of Alabama, Birmingham, explained: ‘This new site could unravel more secrets about the Vikings, whether they were the first Europeans to ‘occupy’ briefly in North America and reveal that the Vikings dared to explore much further into the New World than we ever thought.

The new Viking settlement was found on the edge of Point Rosee in Newfoundland (illustrated above) 400 miles south of another site at L’Anse aux Meadows. They suggest that the Vikings’ mastery of the seas allowed them to venture to North America (illustrated on the map)

‘Typically in archaeology, you only ever get to write a footnote in the history books, but what we seem to have at Point Rosee may be the beginning of an entirely new chapter.’

The Vikings are well known to have been adept seafarers, using the sun and the stars to help pick their way across open stretches of ocean away from the coastline. It is thought the Vikings first discovered America by accident in the autumn of 986AD, according to one historical source, the Saga of the Greenlanders. It tells how Bjarni Herjolfsson was stumbled across North America after being blown off course as he attempted to sail from Norway to Greenland, but he did not go ashore. Inspired by his tales, however, another Viking Leif Ericsson then mounted his own expedition and found North America in 1002.

Finding it fertile land, rich in grapes and berries, he named it Vinland. Eriksson also named two further ‘lands’ on the North American coast – one with flat stones, which he called Helluland, and one that was flat and wooded, named Markland. The discovery of the settlement at Point Rosee now helps to confirm that these legends were in fact true. The settlement uncovered by Dr Parcak, who has been working with the BBC and a team of experts, was initially spotted using high resolution near-infrared images taken by satellites.

Archaeologists found evidence of stones blackened by iron ore processing (pictured), something that the indigenous North American population were not thought to do. It suggests the buildings that stood at the site were inhabited by Vikings, who made extensive use of iron
Using infrared images (pictured) of the site, the archaeologists were able to see the outlines of what they believe were longhouses similar to those used by the Vikings

Over time the structures have altered the soil and the way it retains moisture, changing the vegetation that grow above, making it possible to see the outline of the structures in satellite images. These helped them identify intriguing patterns in Point Rosee, which indicated there were some manmade features and the possible outline of a longhouse similar to those used by the Vikings. During excavations of the site, the team uncovered evidence possible bog iron ore processing.

The settlement at L’Anse aux Meadows was the only other site where pre-Columbian iron processing has been found in North America. The archaeologists discovered around 28lbs of slag in a hearth that they believe was used to roast iron ore before it was smelted in a furnace. Blackened stones, scorched by the extreme heat in this process, were also unearthed at the site. 

Point Rosee is a peninsula on the most south westerly tip of the island of Newfoundland (pictured). It provided a perfect location for the Vikings to set up an outpost, the archaeologists claim

While Inuits are thought to have used some iron from meteors, there is no other evidence of indigenous people processing iron.  The longhouse building they identified appears to have been built using turf, in much the same style as other Viking structures. Black bands in the soil as the team excavated betrayed the presence of turf building blocks that had been used to construct a building. Douglas Bolender said: ‘Right now the simplest answer is that it looks like a small activity area maybe connected to a larger farm that’s norse.

‘If we were in Iceland we wouldn’t think twice about that. But the thing that makes you pause and check every last little bit of it, is that it is in Newfoundland.’ 

If they are right, it means Rosee Point is the most westerly Viking outpost yet discovered. Dr Bolender told National Geographic it could mean that the Viking sagas detailing journey’s to what has been interpreted as North America are true rather than merely legends.

He said: ‘We’re looking here because of the sagas. Nobody would have ever found L’Anse aux Meadows if it weren’t for the sagas. But, the flipside is that we have no idea how reliable they are.’

The remains of a Viking ship burial unearthed in Estonia also features in the BBC documentary (Dan Snow with some of the weapons and artefacts found there are pictured)
Smashed bones thought to have belonged to a Viking were found at a battlefield in Estonia (pictured)

Although the archaeologists leading the excavation are convinced the site was inhabited by Vikings, they say further work is needed to conclusively prove it was a Viking settlement. Nonetheless, Professor Judith Jesch, director of Nottingham University’s Centre for the Study of the Viking Age who was not involved in the discovery, described the find as ‘exciting’. 

She told the told The Telegraph that L’Anse aux Meadows may have been a way-centre as the Vikings ventured further south and that it is likely other sites may yet be unearthed.

She said: ‘Finding Vikings in the United States is the Holy Grail for many people, not least because there are many Americans of Scandinavian descent who would like to think that they were following in the footsteps of their ancestors.

‘But I don’t think they made significant progress past New Brunswick, in Canada.’

The discovery is outlined in a one-off 90 minute BBC documentary called Vikings Uncovered. It will be aired on BBC One in the UK. During the program, historian Dan Snow travels throughout the lands inhabited by the Vikings to explore just how far their influence spread.

Among the other discoveries outlined in the documentary are the remains of a battlefield in Estonia. Smashed bones were found alongside weapons and a Viking ship burial. In Portmahomack in Easter Ross, in the Scottish Highlands, archaeologists have discovered evidence that a monastery there was utterly destroyed by a Viking raid. Smashed sculptures were found with the ashes of the buildings of what had been once a prosperous community.

Skull fragments found at the site – thought to have belonged to monks – reveal the violence of the attack. Speaking about the find in Newfoundland, Mr Snow said: ‘The Vikings Uncovered was one of the most exciting projects of my career.

‘I was able to follow Dr Sarah Parcak and her team as they carried out pioneering research, using satellite imagery, in an attempt to unlock one of history’s greatest mysteries.

‘Were the Vikings really the first Europeans to settle North America? We know of one Viking site on the very northern tip of Newfoundland but was this part of a wider Viking territory?

‘It felt like Sarah’s team were making history, both in the high tech labs and on the ground in windswept Newfoundland, and I got to watch the entire process.’

Mexico analyzes bones and objects from 1,400 years ago found in Michoacán

Mexico analyzes bones and objects from 1,400 years ago found in Michoacán

The skeletal remains of a woman and 19,428 associated objects, found in 2011 in the archaeological zone of Tingambato, in the western state of Michoacán, were analyzed by researchers from the National Institute of Anthropology and History (INAH), who pointed out that its antiquity dates back to 630 AD.

In a statement, it was explained that the skeletal remains of the woman were found inside a burial chamber “built five meters deep, with strong stone walls and a vaulted ceiling of slabs in a spiral direction, where she was buried with a rich trousseau made up of 19,428 shell and lapidary objects “.

The archaeologist José Luis Punzo Díaz, a researcher at the INAH Michoacán Center, indicated that the results revealed the significance of this burial and of the inhumed character, placing it “as one of the most important archaeology in western Mexico, particularly Michoacán.”

Osteological and ancient DNA analysis confirmed that the skeletal remains deposited in Tomb II of the aforementioned archaeological zone belonged to a young woman between 16 and 19 years old and its antiquity dates back to 630 AD.

This according to the radiocarbon collagen analysis done at the National Autonomous University of Mexico (UNAM), whose data coincides with the stage of greatest growth of Tingambato, from 550 to 850 AD, said Alejandro Valdés Herrera, a member of the research project.

Analysis of the skeletal remains with computerized axial tomography

Due to the fragmentation and poor preservation conditions of the skull, a careful reconstruction was made in the Laboratory of Physical Anthropology of the INAH-Michoacán Center, where it was discovered that it presented cephalic deformation, as well as dental modification work.

“Although these modifications were recurrent in his time, they are associated with certain groups in society, which leads us to think that he was part of the local elite,” explained Valdés Herrera.

While when analyzing his teeth, they observed that the modifications were not worn or showed evidence of use, so they could have been carried out at a time close to his death.

The studies of the materials, which began in 2016, also determined various paleopathologies, which indicate that he suffered periods of illness such as fever and a mild degree of malnutrition, although they do not appear to be the cause of death, which is still unknown.

When analyzing 18,601 elements made with seashells, it was determined that most of the beads and earrings are of the Spondylus princeps species, from the Pacific, peculiar for its orange hue, which was highly appreciated by ancient cultures.

About the 827 lapidary elements, the specialists highlighted that most of the greenstone beads correspond to a mineral called amazonite, whose origin is not yet specified, but important veins are known in the state of Chihuahua.

According to studies, Tingambato was a privileged site due to its location, at the entrance to Tierra Caliente and the cold mountain range of Michoacán, which arose in the year 0 and had a constant occupation until 900 AD.

Oldest Horseshoe Crab Fossil Found, 445 Million Years Old

Oldest Horseshoe Crab Fossil Found, 445 Million Years Old

Few modern animals are as deserving of the title “living fossil” as the lowly horseshoe crab. Seemingly unchanged since before the Age of Dinosaurs, these venerable sea creatures can now claim a history that reaches back almost half a billion years.

The oldest horseshoe crab in the fossil record (Lunataspis aurora, left) is 445 million years old and was discovered in Ordovician strata from Manitoba, Canada. Horseshoe crab shells are made of protein and normally are not mineralized like typical fossils, making this a truly remarkable find. Despite the age of this fossil, it looks remarkably similar to the modern animal pictured to the right

In a collaborative research article published recently in the British journal Palaeontology, a team of Canadian scientists revealed rare new horseshoe crab fossils from 445 million-year-old Ordovician age rocks in central and northern Manitoba, which are about 100 million years older than any previously known forms.

Palaeontologist Dave Rudkin from the Royal Ontario Museum, with colleagues Dr. Graham Young of The Manitoba Museum (Winnipeg) and Dr. Godfrey Nowlan at the Geological Survey of Canada (Calgary), gave their remarkable new fossils the scientific name Lunataspis aurora, meaning literally “crescent moon shield of the dawn” in reference to their shape, geological age and northerly discovery sites.

Although they are more “primitive” in several aspects than other known horseshoe crabs, their resemblance to living forms is unmistakable.

The fossil horseshoe crabs were recovered in the course of fieldwork studies on ancient tropical seashore deposits, providing yet another important link to their modern descendants that are today found along warmer seashores of the eastern United States and the Indian Ocean.

One of the fossils of the new genus of horseshoe crab (Lunataspis aurora) was photographed underwater to show some of the fine details.

This is particularly significant, explains Rudkin. “Understanding how horseshoe crabs adapted to this ecological niche very early on, and then remained there through thick and thin, can give us insights into how ocean and shoreline ecosystems have developed through deep time.”

Today, marine shorelines worldwide are being threatened by human activity, and although some horseshoe crab populations are endangered, their enviably long record on Earth indicates that they have successfully weathered many previous crises, including the mass extinction that saw the demise of the dinosaurs and many other life forms 65 million years ago.

“We do need to be concerned about horseshoe crabs and many of the other unusual life forms found on marine shores,” said Dr. Young.

“Nevertheless, we can also be mildly optimistic that some of these things have demonstrated a toughness that may allow them to survive our abuse of these environments.”

Living horseshoe crabs are extensively studied, especially in the fields of ecology and medical research. The exciting discovery of these unusual early fossil relatives adds a new introductory chapter to their remarkable story.

David Rudkin is Assistant Curator in the Department of Natural History (Palaeobiology) at the Royal Ontario Museum and holds an appointment to the Department of Geology, University of Toronto, as a Lecturer in palaeontology.

Rudkin joined the former Department of Invertebrate Palaeontology at the ROM in 1975 and began working on fossils from the Burgess Shale in British Columbia.

Humans Arrived in North America More Than 30,000 Years Ago, Study Suggests

Humans Arrived in North America More Than 30,000 Years Ago, Study Suggests

According to an unexpected finding made by an Iowa State University researcher, the earliest people may have arrived in North America approximately 20,000 years earlier than previously thought.

Andrew Somerville, an assistant professor of anthropology in world languages and cultures, says he and his colleagues made the discovery while studying the origins of agriculture in the Tehuacan Valley in Mexico.

As part of that work, they wanted to establish a date for the earliest human occupation of the Coxcatlan Cave in the valley, so they obtained radiocarbon dates for several rabbit and deer bones that were collected from the cave in the 1960s as part of the Tehuacan Archaeological-Botanical Project.

Coxcatlan Cave, a rock shelter located within the southern portion of the Tehuacan Valley in Mexico.

The dates for the bones suddenly took Somerville and his colleagues in a different direction with their work. The dates for the bone samples from the early depositional levels of the cave ranged from 33,448 to 28,279 years old.

Somerville says even though previous studies had not dated items from the bottom of the cave, he was not expecting such old ages. The findings add to the debate over a long-standing theory that the first humans crossed the Bering Land Bridge into the Americas 13,000 years ago.

“We weren’t trying to weigh in on this debate or even find really old samples. We were just trying to situate our agricultural study with a firmer timeline,” Somerville said. “We were surprised to find these really old dates at the bottom of the cave, and it means that we need to take a closer look at the artefacts recovered from those levels.”

Somerville says the findings provide researchers with a better understanding of the chronology of the region. Previous studies relied on charcoal and plant samples, but he says the bones were a better material for dating. However, questions still remain. Most importantly, is there a human link to the bottom layer of the cave where the bones were found?

To answer that question, Somerville and Matthew Hill, ISU associate professor of anthropology, plan to take a closer look at the bone samples for evidence of cut marks that indicate the bones were butchered by a stone tool or human or thermal alternations that suggest the bones were boiled or roasted over a fire. He says the possible stone tools from the early levels of the cave may also yield clues.

“Determining whether the stone artifacts were products of human manufacture or if they were just naturally chipped stones would be one way to get to the bottom of this,” Somerville said. “If we can find strong evidence that humans did in fact make and use these tools, that’s another way we can move forward.”

Year-long journey to even find the bones

Not only was this discovery unexpected, but the process of tracking down the animal bones to take samples was more than Somerville anticipated. The collection of artifacts from the 1960s Tehuacan Archaeological-Botanical Project was distributed to different museums and labs in Mexico and the United States, and it was unclear where the animal bones were sent.

After a year of emails and cold calls, Somerville and his collaborator, Isabel Casar from the National Autonomous University of Mexico, had a potential lead for a lab in Mexico City. The lab director, Joaquin Arroyo-Cabrales, agreed to give Somerville and Casar a tour to help search for the missing collection. The tour proved to be beneficial. Among the countless boxes of artifacts, they found what they were looking for.

“Having spent months trying to locate the bones, we were excited to find them tucked away on the bottom shelf in a dark corner of the lab,” Somerville said. “At the time, we felt that was a great discovery, we had no idea it would lead to this.”

Once he located the bones, Somerville got permission from the Mexican government to take small samples — about 3/4 inch in length and 1/4 inch in width — from 17 bones (eight rabbits and nine deer) for radiocarbon dating. If closer examination of the bones provides evidence of a human link, Somerville says it will change what we know about the timing and how the first people came to America.

“Pushing the arrival of humans in North America back to over 30,000 years ago would mean that humans were already in North America prior to the period of the Last Glacial Maximum, when the Ice Age was at its absolute worst,” Somerville said.

“Large parts of North America would have been inhospitable to human populations. The glaciers would have completely blocked any passage over land coming from Alaska and Canada, which means people probably would have had to come to the Americas by boats down the Pacific coast.”

New pyramid discovered in Mexico

New pyramid discovered in Mexico

Archaeologists have found a new pyramid in Tlacochcalco (modern-day Mexico). The town was a political centre during the pre-Hispanic period.

According to Mexico’s National Institute of Anthropology and History, the ruins of Tlacochcalco are located in the modern-day town of Tlalmanalco.

According to the archaeologist of INAH, Herve Victor Monterrosa Desruelle”This area,” he explained, “is a continuum of platforms and levellings, reflecting a pre-Hispanic occupation, but unfortunately, houses have been built on them, although in this case, the owner of the property where the remains were located, when he wanted to build, turned to the Institute in order to examine a mound found on his land, which when analysed revealed the structure.”

Detail of some spindle whorls found between levelling walls

Monterrosa explained that the elements of the foundation discovered are only a third of the volume of the construction, the rest was razed to the ground by the urban sprawl.

The pyramid was buried under a mound. Its base was 12 to 18 meters long and 9 meters tall. The pyramid had three levels, but only a third of the original structure has been preserved. Thus, the base originally measured 35 meters by 45 meters.

New pyramid discovered in Mexico

“In the clearance of the building, by means of approach shafts, we located different elements such as the walls, which are being attended to along the length of each facade.

Once this intervention is done, the second phase will be to give volume and solidity to the structure, which is deteriorated, especially in the north-western part, by means of consolidation and restitution works”.

Another of the specialists involved in the project, developed by the Ministry of Culture through the Centro INAH Estado de Mexico, the archaeologist and architect Ricardo Arredondo Rojas, pointed out that in the first section, a number of rooms were found with the remains of stucco floors, with which the height of the walls could be determined.

Architecturally, he said, the structure shows two phases of occupation: the first, from 1350 to 1465 – during Chalco’s hegemonic period – shows a clear Chalca influence, with a construction system that uses mortar based on lime and crushed tezontle, as well as mud from the lake as a binder, with the stone quarry work standing out for its technical work.

View of the northwest corner of the pyramidal base

The second stage, with the occupation of the Mexica Empire in this region (from 1465 until the time of contact with the Spaniards), corresponds to the phase of expansion of the base, which can be seen in the series of caissons for the foundation fillings that were constructed in this area.

“However, the quality of the work declines completely, it becomes coarser, which indicates changes in the occupation and the sense of urban space.”

“The latter shows us how they gained land from the nearby ravine, filling the structure with these small structures that supported it, which they filled with waste ceramic material from an earlier period.”

Arredondo Rojas commented that, if the original volume of the pyramidal base were restored, “we would be talking about approximate dimensions of between 35 and 45 metres on a side, in its first level”.

Detail of the tripod plate found in front of the wall of the third section on the north facade

According to the archaeological data obtained so far, both researchers suggest that it is an elite housing structure, perhaps a palace area, given that the ceramic material found at the site is fine, although it remains to be analysed.

They stressed that it is also necessary to corroborate the sequences of occupation, because even when the remains of the building are available, the archaeological material, mainly ceramics (sherds and spindle whorls), are found mixed up with the construction fills or in the deposits of the rubble.

“We need to locate and excavate more sealed contexts to determine these, so the excavations will conclude in September, and then the archaeological materials will be analysed in the office,” they added.

Herve Monterrosa explained that when people talk about sites from the Postclassic period, such as this one, they are approached with an ethnocentric view of the Mexica; “however, the one being excavated is Chalca, whose importance lies in having been, like Tlacochcalco, the head of the altepetl (in the Mexica period) and one of the five original lordships of Chalco, along with Tenango-Tepopula, Xico-Chalco-Atenco, Amecameca and Xochimilco-Chimalhuacan.

Tlalmanalco was one of the late-founded Chalco kingdoms, established in the mid-14th century, which, at the end of the Mexica incursion at the site, in the Contact stage, became the main socio-political entity of the Chalcayotl, the league of villages in the region.

“It was in this settlement where Hernan Cortes, according to his Third Letter of Relation, spent the night to negotiate the alliance with the lords of Chalco, who would lead him to the city of Mexico-Tenochtitlan,” he concluded.
