The Royal Burials of 65 Celtic Kings Identified in England and Wales

The Royal Burials of 65 Celtic Kings Identified in England and Wales

Roughly 60 newly-discovered royal graves in the north and west were of British or Irish Celtic origin, according to a new study. A number of English kings in the post-Roman era were of Irish origin, with several Celtic tombs uncovered in the west and north of Britain.

Professor Ken Dark of the University of Reading and Spain’s University of Navarra, a leading expert on the period immediately after the collapse of Roman rule in Britain, has published a new report revealing the locations of between 55 and 65 Celtic-British royal graves from the dark ages. 

The newly-discovered graves are located in Wales, Cornwall, Devon, and Somerset and share several similarities with Irish royal tombs, according to Dark’s research. 

England consisted of a series of tiny states following the collapse of the Roman Empire in the 5th century, with Anglo-Saxons of Germanic origin dominating in the south and celts of British and Irish origin ruling in the north and west. 

The names of the kings buried in the newly-discovered graves are currently unknown, but Dark says that they are likely to have been kings, sub-kings, or other royals in the British kingdoms of Gwynedd (northwest Wales), Dyfed (southwest Wales), Powys (central east Wales), Brycheiniog (modern Breckonshire) and Dumnonia (now southwest England). 

The study of early Celtic graves in Britain remains in its infancy. Archaeologists only ever identified one definite indigenous British royal burial site, while the graves discovered by Dark represent just 0.1% of British-Celtic dark age burials.

The graves have square or rectangular ditched enclosures around them, while many appear to have entry gates or access causeways.

The enclosures, which measure up to 10 meters squared, often feature timber posts or a stone-lined pit. 

The graves had been gradually discovered over the years, but Dark is the first scholar to realize their probably royal status. 

Dark has also identified a further 43 sites as likely royal burial sites in Ireland. 

One of the First Known Chemical Attacks Took Place 1,700 Years Ago in Syria

One of the First Known Chemical Attacks Took Place 1,700 Years Ago in Syria

A researcher from the University of Leicester has identified what looks to be the oldest archaeological evidence for chemical warfare — from Roman times.

At the meeting of the Archaeological Institute of America, University of Leicester archaeologist Simon James presented CSI-style arguments that about twenty Roman soldiers, found in a siege-mine at the city of Dura-Europos, Syria, met their deaths not as a result of sword or spear, but through asphyxiation.

Dura-Europos on the Euphrates was conquered by the Romans who installed a large garrison. Around AD 256, the city was subjected to a ferocious siege by an army from the powerful new Sasanian Persian empire.

The dramatic story is told entirely from archaeological remains; no ancient text describes it. Excavations during the 1920s-30s, renewed in recent years, have resulted in spectacular and gruesome discoveries.

The Sasanians used the full range of ancient siege techniques to break into the city, including mining operations to breach the walls. Roman defenders responded with ‘counter-mines’ to thwart the attackers. In one of these narrow, low galleries, a pile of bodies, representing about twenty Roman soldiers still with their arms, was found in the 1930s.

While also conducting new fieldwork at the site, James has recently reappraised this coldest of cold-case ‘crime scenes’, in an attempt to understand exactly how these Romans died, and came to be lying where they were found.

Dr James, Reader in the School of Archaeology and Ancient History at the University of Leicester, said: “It is evident that, when mine and countermine met, the Romans lost the ensuing struggle.

Careful analysis of the disposition of the corpses shows they had been stacked at the mouth of the countermine by the Persians, using their victims to create a wall of bodies and shields, keeping Roman counterattack at bay while they set fire to the countermine, collapsing it, allowing the Persians to resume sapping the walls.

This explains why the bodies were where they were found. But how did they die? For the Persians to kill twenty men in a space less than 2m high or wide, and about 11m long, required superhuman combat powers—or something more insidious.”

Finds from the Roman tunnel revealed that the Persians used bitumen and sulphur crystals to get it burning. These provided a vital clue. When ignited, such materials give off dense clouds of choking gases. “The Persians will have heard the Romans tunnelling,” says James, “and prepared a nasty surprise for them.

I think the Sasanians placed braziers and bellows in their gallery, and when the Romans broke through, added the chemicals and pumped choking clouds into the Roman tunnel.

The Roman assault party were unconscious in seconds, dead in minutes. Use of such smoke generators in siege mines is actually mentioned in classical texts, and it is clear from the archaeological evidence at Dura that the Sasanian Persians were as knowledgeable in siege warfare as the Romans; they surely knew of this grim tactic.”

Ironically, this Persian mine failed to bring the walls down, but it is clear that the Sasanians somehow broke into the city.

James recently excavated a ‘machine-gun belt’, a row of catapult bolts, ready to use by the wall of the Roman camp inside the city, representing the last stand of the garrison during the final street fighting.

The defenders and inhabitants were slaughtered or deported to Persia, the city abandoned forever, leaving its gruesome secrets undisturbed until modern archaeological research began to reveal them.

DNA from child burials reveals ‘profoundly different’ human landscape in ancient Africa

DNA from child burials reveals ‘profoundly different’ human landscape in ancient Africa

Central Africa is too hot and humid for ancient DNA to survive—or so researchers thought. But now the bones of four children buried thousands of years ago in a rock shelter in the grasslands of Cameroon have yielded enough DNA for scientists to analyze.

It’s the first ancient DNA from humans in the region, and as the team reports today in Nature, it holds multiple surprises. For one, the area today is the homeland of Bantu speakers, the majority group in western and Central Africa.

But the children turned out to be most closely related to hunter-gatherers such as the Baka and Aka—groups traditionally known as “pygmies”—who today live at least 500 kilometres away in the rainforests of western Central Africa.

DNA from child burials reveals ‘profoundly different' human landscape in ancient Africa
People like these Baka hunter-gatherers once ranged well beyond their current homeland in Central Africa.

“In the supposed cradle of Bantu languages and, therefore, Bantu people, these people are basically ‘pygmy’ hunter-gatherers,” says Lluís Quintana-Murci, a population geneticist at the Pasteur Institute and CNRS, the French national research agency, who was not part of the new study.

He and others have long suspected that these groups had a larger range before the Bantu population exploded 3000 years ago.

The second big surprise came when the team compared the children’s DNA to other genetic data from Africa and found hints that the Baka, Aka, and other Central African hunter-gatherers belong to one of the most ancient lineages of modern humans, with roots going back 250,000 years.

In the new study, geneticists and archaeologists took samples from the DNA-rich inner ear bones of the four children, who were buried 3000 and 8000 years ago at the famous archaeological site of Shum Laka.

The researchers were able to sequence high-quality full genomes from two of the children and partial genomes from the other two.

Comparing the sequences to those of living Africans, they found that the four children were distant cousins and that all had inherited about one-third of their DNA from ancestors most closely related to the hunter-gatherers of western Central Africa.

Another two-thirds of children’s DNA came from an ancient “basal” source in West Africa, including some from a “long lost ghost population of modern humans that we didn’t know about before,” says population geneticist David Reich of Harvard University, leader of the study.

The discovery underscores the diversity of African groups that inhabited the continent before the Bantus began to herd livestock in the grassy highlands of western Central Africa.

The Bantus made pottery and forged iron, and their burgeoning populations rapidly displaced hunter-gatherers across Africa. Analyzing DNA from a time before this expansion offers “a glimpse of a human landscape that is profoundly different than today,” Reich says.

The team compared the children’s DNA to ancient DNA extracted earlier from a 4500-year-old individual from Mota Cave in Ethiopia and sequences from other ancient and living Africans, using various statistical methods to sort out how they all were related, which groups came first, and when they split from one another.

The team’s bold new model pushes back Central African hunter-gatherer origins to 200,000 to 250,000 years ago—not long after our species evolved.

The model suggests their lineage split from three other modern human lineages: one leading to the Khoisan hunter-gatherers in southern Africa, one to East Africans, and one to a now-extinct “ghost” population.

Early diversification of modern humans fits the great variation seen in fossils of early Homo sapiens, says paleoanthropologist Katerina Harvati of the University of Tübingen, who is not part of this study.

The lineages would have parted company and moved off into different parts of Africa 200,000 to 250,000 years ago, preserving their distinctness by only occasionally interbreeding at the boundaries.

But others say that although the new study offers compelling new evidence, the data aren’t yet solid enough to build a reliable model.

“It needs to be further tested with additional whole-genome data from both modern and, if possible, ancient DNA from more Africans,” says evolutionary geneticist Sarah Tishkoff of the University of Pennsylvania.

That may be possible. A third key lesson from the study is that ancient DNA can be extracted from bones in Central Africa after all. “The future is not as bleak for ancient DNA in these regions,” says population geneticist Joshua Akey of Princeton University.

Crimean Atlantis: Remarkable Ancient Underwater City Of Akra

Crimean Atlantis: Remarkable Ancient Underwater City Of Akra

The ancient city of Akra was once a beautiful place famous for its outstanding architecture. Then, its glory and prosperity came suddenly to an end. About 2,000 years ago, the city of Akra was submerged.

Underwater archaeologists have discovered several of the ancient city’s ruins, defensive walls, houses, and a mysterious tower.

The underwater city of Akra still remains vastly unexplored and has many more secrets to reveal.

Ancient City Of Akra Belonged To The Bosporus Kingdom

Ancient historians such as Strabo and Ptolemy mentioned the city’s existence. Akra was part of the Bosporus Kingdom,  an ancient state on the northern coast of the Black Sea, founded ca 480 B.C through an alliance of existing Greek city-states.

The kingdom’s capital was Panticapaeum (present-day Kerch). It was ruled by the Archaeanactid and then by the Spartocid dynasty, which endured for over 300 years.

Founded by the settlers from Nymphaeum or Panticapaeum in the late 6th century B. C, the city of Akra was a large shopping centre visited by many people from various corners of the ancient kingdom.

Many Of The Ancient Underwater Ruins Are Well-Preserved

The underwater city of Akra was accidentally discovered in 1981 when a high school boy walking along the beach found 150 ancient coins in the sand. This discovery prompted researchers to launch an expedition to find out what ancient treasures were resting underwater.

Underwater archaeologists from Ukraine and Russia investigated the ancient, submerged ruins.

Since then, a team of underwater archaeologists from Ukraine and Russia has discovered thick defensive walls, two towers, remains of well-preserved ancient houses, and other valuable ancient artefacts such as coins, amphorae, arrowheads, and pottery.

One of the discovered towers is still in very good condition. Considering the towers have survived underwater for more than 2,000 years it clearly shows the ancient people of Akra possessed sophisticated knowledge of architecture. The tower probably served as part of the city’s defence buildings.

In 2011, researchers also found remains of the wreck of a wooden ship in the distance of several kilometers from Akra on the depth of 4 meters. The observed length of the ship was about 30 meters; its hull was covered with brass plates.

Several of the ancient underwater structures are still in good condition.

While other ancient cities of the Black Sea region – Pantikapea, Olbia, and Chersonesos were almost completely destroyed by the sea, it can be said that the ancient city of Akra was lucky.

According to underwater archaeologists Viktor Vakhonieiev and Sergey Solovyev, features of the wave conditions in this part of Kerch Peninsula led to the fact that the cultural layers of the ancient city were not mainly washed away, and its building constructions were not completely destroyed, but only partially covered with sea sand deposits.

What more is hidden beneath the waters of the Black Sea?

The Black Sea can become a significant region for future underwater archaeologists. Not only are natural well-preserved here, but there are also many intact submerged ancient vessels, sites, and cities resting beneath the waters.

In May 2013, the ancient underwater city of Akra became a tourist attraction. However, according to the Crimean Ministry of Culture and Tourism, permissions to visit the underwater city of Acre are extremely limited. Tourists are only allowed to visit the flooded city from late May to early June.

Scientists say they have much more to explore, and they still haven’t been able to reach many of the underwater ruins of ancient Akra.

All these amazing underwater discoveries Make you wonder what more is hidden beneath the waters of the Black Sea.

“Incredibly rare” 180-million-year-old giant “sea dragon” fossil discovered in the U.K.

“Incredibly rare” 180-million-year-old giant “sea dragon” fossil discovered in the U.K.

Palaeontologists have made a massive discovery in the United Kingdom’s smallest county — the fossilized remains of a giant Jurassic sea creature. The fossil, which researchers said is “very well-preserved,” is said to be the “palaeontological discovery of a lifetime,” according to the Leicestershire and Rutland Wildlife Trust.

The fossil was found at the Rutland Water Nature Reserve in central England in February 2021, according to an announcement from the wildlife trust.

Joe Davis, who works on the water conservation team for the trust, found it during a routine draining procedure for re-landscaping. 

"Incredibly rare" 180-million-year-old giant "sea dragon" fossil discovered in the U.K.
Ichthyosaur skeleton found at Rutland Water Nature Reserve in central England, August 26, 2021.

At first, he said in a statement, he thought the remains were clay pipes sticking out of the mud, except that “they looked organic.” He told a colleague that they looked like vertebrae, and when they got closer, they saw “what indisputably looked like a spine” as well as a jawbone at the spine’s end. 

“We couldn’t quite believe it,” Davis said. “The find has been absolutely fascinating and a real career highlight. It’s great to learn so much from the discovery and to think that this amazing creature was once swimming in seas above us.” 

The fossil was excavated in August and September and has since been identified as an ichthyosaur, a marine reptile that somewhat resembled dolphins.

This particular fossil found nearly complete, is nearly 33 feet long and is roughly 180 million years old, researchers said. Its skull measures more than 6.5 feet long.

Davis told the BBC that the fossil was “very well-preserved, better than I think we could have all imagined.” 

Ichthyosaur expert Dean Lomax, who helped with the fossil’s research, said that the find is the “largest ichthyosaur skeleton ever discovered in Britain.” 

“These animals, they first appeared in a time called the Triassic period around roughly 250 million years ago,” Lomax said in a video for Rutland Water Nature Reserve. “Our specimen, the Rutland Ichthyosaur, or the Rutland Sea Dragon, is the biggest complete ichthyosaur ever found in Britain in over 200 years of collecting these things scientifically, which is an incredible feat.” 

Ichthyosaurs are not swimming dinosaurs, he clarified. 

According to the company Anglian Water, which helps maintain the reservoir in which the fossil was found, ichthyosaurs of this size and completeness are “incredibly rare,” especially in the U.K., with most comparable examples being found in Germany and North America. 

Alicia Kearns, who represents Rutland Melton in Parliament, said the discovery “surpassed every possible expectation.” 

“It is utterly awe-inspiring,” she said. 

Though the largest, this was not the first ichthyosaur fossil found in the reservoir. The Wildlife Trust said that two incomplete and “much smaller” remains were found in the ’70s when the reservoir was first being constructed. 

The palaeontologists working on the remains are continuing their research and are working on an academic paper about the findings. 

Stunning 3D image recreates real Stone Age woman

Stunning 3D image recreates real Stone Age woman

A Stone Age woman who lived 4,000 years ago is leaning on her walking stick and looking ahead as a spirited young boy bursts into a run, in a stunning life-size reconstruction now on display in Sweden.

Although her likeness is new — it debuted last month in an exhibit about ancient people at Västernorrlands Museum — researchers have known about this woman’s existence for nearly a century. During the construction of a road in the hamlet of Lagmansören in 1923, workers found her skeletal remains buried next to the remains of a child, likely a 7-year-old boy.

“With our eyes and perhaps in all times, you tend to think that this is a mother and son,” said Oscar Nilsson, the Sweden-based forensic artist who spent 350 hours creating the lifelike model.

“They could be. Or they could be siblings: sister and brother. They could be relatives, or they could just be tribe friends. We don’t know, because the DNA was not that well preserved to establish this relationship.”

But as Nilsson molded the woman’s posture and sculpted her face, he pretended that she was near her son who was scampering ahead of her. “She’s looking with the mother’s eyes — both with love and a bit of discipline,” Nilsson told Live Science. This stern but tender gaze looks as if she’s on the cusp of calling out to the boy, telling him to be careful.

Stunning 3D image recreates real Stone Age woman
This reconstruction is based on the remains of a Neolithic woman who lived about 4,000 years ago in what is now Sweden.

The Neolithic woman and youngster were interred in a cist grave, a burial built with long, flat stones in the shape of a coffin. The woman died in her late 20s or early 30s, and at 4 feet, 11 inches (150 centimetres) in height, “she was not a very tall person,” even for the Neolithic period, Nilsson said.

The woman’s remains didn’t show any signs of malnutrition, injury or diseases, although it’s possible that she died of an illness that didn’t leave a mark on her remains, Nilsson said.

“She seems to have had a good life,” he said. She ate land-based food, an examination of the isotopes (different versions of elements) in her teeth revealed, which was odd given that her grave was found near a fish-filled river near the coast, he said.

When Nilsson received the commission to reconstruct the woman two years ago, he scanned her skull and made a copy of it with a plastic 3D printer. As with other reconstructions he’s created, including those of an ancient Wari queen from what is now Peru and a Stone Age man whose head was found on a spike, Nilsson had to take into account the ancient individual’s sex, age, weight and ethnicity — factors that can influence the person’s facial tissue thickness and general appearance. But because the woman’s DNA was too degraded, he wasn’t sure about her genetic background, hair or eye colour.

So Nilsson took an educated guess about her appearance. There were three large migration waves into ancient Scandinavia: During the first, hunter-gatherers with dark skin who tended to have blue eyes arrived between 12,000 and 10,000 years ago; the second wave included pale-skinned, dark-haired and brown-eyed farmers from further south who moved north about 5,000 to 4,000 years ago when this woman was alive; and the third wave included the Yamnaya (also spelled Yamna) culture from modern-day Ukraine, who were a bit darker-skinned than the farmers and brought the art of metal making with them when they arrived about 3,500 years ago, making them the first Bronze Age culture in the region, Nilsson said.

Based on this information, Nilsson gave the woman brown hair and eyes, and light skin like the farmers’. Even so, the woman wasn’t necessarily a full-time farmer; she likely participated in a mix of hunting and gathering as well as agricultural practices, he said.

“We can’t say for sure whether she was living a nomadic life if she was living the life of the early farmers; it’s impossible to say,” Nilsson said. “But we have chosen to make the safest interpretation, which is she was both because, of course, there was a transition period of many hundreds of years when they left the old way of living.”

Fancy furs, Stone Age style

In the reconstruction, the woman from Lagmansören is dressed head to toe in fur and leather. This is the work of Helena Gjaerum, a Sweden-based independent archaeologist who uses Stone Age techniques for tanning leather. 

Before dressing the model, Gjaerum studied the ancient climate, landscape, vegetation and animal life of Neolithic Lagmansören. Based on what she uncovered, she designed the woman’s clothes out of deer, moose and elk and the shoes out of reindeer, beaver and fox. The woman likely stuffed hay inside the shoes for padding, noted Gjaerum, who took inspiration from clothing worn by Indigenous Americans and Indigenous Siberians, as well as the leather clothing of Özti the Iceman mummy, who lived about 5,300 years ago in the Italian Alps.

Preparing the clothes entailed hours of labour. Gjaerum, who acquired real animal remains, scraped the flesh off the skins and then put them in a river — a method that helps loosen the fur from the skin. Next, she scraped off the fur and slathered on a solution made of moose brain, a fatty mixture that bonds with skin fibres. Without this mixture, the skin would stiffen and could easily rot if it got wet, she said.

The next several steps involved massaging, boiling, stretching and smoking the skins and then finally designing the clothing. Gjaerum’s young son, who was about the same height as the Stone Age woman, served as a helpful model, Gjaerum said.

She made the clothing as comfortable and practical as possible — for instance, by not putting a seam at the top of the shoulder, where water might seep in during rainy weather.

Often, modern people think of Stone Age humans as primitive, dressed in ugly, toga-like furs as in “The Far Side” comics. But Gjaerum challenged that perception. “I think it would be crazy to think she’d have primitive clothes,” Gjaerum told Live Science. “I wanted to make her dress like you could dress today” because you are both Homo sapiens.

Burnt seeds show people used tobacco 12,000 years ago

Burnt seeds show people used tobacco 12,000 years ago

Four charred tobacco plant seeds found in an ancient Utah fireplace suggest early Americans may have been using the plant 12,300 years ago. The finding makes the first known use of tobacco some 9,000 years earlier than previously thought.

Archaeologists found the seeds in the Great Salt Lake Desert

Researchers believe hunter-gatherers in the Great Salt Lake Desert may have sucked or smoked wads of the plant.

Until now, the earliest evidence of tobacco use was a 3,300-year-old smoking pipe discovered in Alabama.

Archaeologists discovered the millimetre-wide seeds at the Wishbone site, an ancient camp in the desert in what is now northern Utah.

There, they found the remnants of an ancient hearth that was surrounded by bone and stone artefacts. These included duck bones, stone tools, and a spear-tip bearing the remains of blood from a mammoth or an early form of an elephant.

The charred remains of one of the tobacco plant seeds

Their findings suggest the native American hunter-gatherers may have consumed the tobacco while cooking or toolmaking, the scientists say in a paper published in the journal Nature Human Behaviour.

The tobacco plant is native to the Americas and contains the psychoactive addictive substance nicotine.

Tobacco was widely cultivated and dispersed around the world following the arrival of Europeans in the Americas at the end of the 15th Century.

“The tobacco seeds were a big surprise. They are incredibly small and rare to be preserved,” Daron Duke of the Far Western Anthropological Research Group told the New Scientist.

“This suggests that people learned the intoxicant properties of tobacco relatively early in their time here rather than only with domestication and agriculture thousands of years later.”

Today, the Great Salt Lake Desert is a large dry lake. But 12,300 years ago, the camp would have been on a vast marshland.

“We know very little about their culture,” Mr Duke said of the hunter-gatherers. “The thing that intrigues me the most about this find is the social window it gives to a simple activity in an undocumented past. My imagination runs wild.”

The largest Aztec temple was decorated with over 100 starfish

The largest Aztec temple was decorated with over 100 starfish

Aztec priests at Tenochtitlán offered a whole galaxy of starfish to the war god Huitzilopochtli 700 years ago, along with a trove of other objects from the distant edges of the Aztec Empire. Archaeologists from Mexico’s National Institute of Anthropology and History (INAH) recently unearthed the offering on the site of the Templo Mayor, the main temple in the Aztec capital of Tenochtitlán, in what is now Mexico City.

This imprint preserves details of the internal structure of the starfish, as well as its overall shape. It’s one of 164 starfish recently unearthed at the Templo Mayor site in Mexico City.

Ahuizotl, coast to coast

The offering included 164 starfish from a species called Nidorella armata, known less formally as the chocolate chip starfish because it’s mostly the colour of cookie dough, but it has dark spots. (It shares the nickname with the other chocolate chip sea star, Protoreaster nodosus, which provides an excellent argument in favour of scientific names.) Nidorella armata lives along the Pacific coastline from Mexico south to Peru, where it hangs out on shallow-water reefs of rock and coral.

For Tenochtitlán, the nearest source of chocolate chip starfish would have been nearly 300 kilometres away from the Aztec capital. Chunks of coral found in the same offering came from about the same distance away but in roughly the opposite direction—the western end of the Gulf of Mexico. At the time, these items came from the farthest eastern and western edges of the Aztec Empire, places that the Aztec ruler Ahuizotl had only recently conquered.

Ahuizotl took the throne in 1486, and he jumped straight into two major projects: renovating the capital, including the Templo Mayor, and expanding the borders of his empire. His campaigns nearly doubled the size of the Aztec Empire, stretching Aztec rule west to the Pacific coast of Mexico and southeast to Guatemala. All that conquest meant that the Aztecs could easily bring starfish from the Pacific and corals from the Gulf of Mexico, along with an assortment of marine shells (and even pufferfish) to Tenochtitlán to lay before their gods.

Conquistadors ruin everything

Back in the capital, Ahuizotl ordered the reconstruction of large parts of the city. His efforts included expanding the Templo Mayor, which in Aztec terms meant building a new, bigger outer layer over the top of the previous temple. (The prior construction was often ritually “killed” before the new one could be consecrated.) That’s convenient for modern archaeologists, who can date each layer of construction at the Templo Mayor.

The oldest part of the temple dates to around 1325, when a group of people called the Mexica migrated into the area surrounding what is now Mexico City. There, according to Mexica lore, their leaders saw an eagle perched on a prickly pear and eating a snake; it was the sign their priests had told them to expect from Huitzilopochtli, and it’s an image you might recognize from the modern Mexican flag. At the site, the Mexica built a city called Tenochtitlán, and from there, they ruled the Aztec Empire.

Huitzilopochtli shared the Templo Mayor with the rain and farming god Tlaloc; each god had his own shrine at the top of the pyramid, reached by separate staircases. Ahuizotl’s expansion, where archaeologists found the starfish offering, is the sixth layer of the Templo Mayor. Only one more layer would be added before the temple’s destruction.

Ahuizotl was the eighth ruler of the Aztec Empire and the last to rule before the Spanish conquistadors, led by Hernán Cortés, arrived and changed everything. Cortés arrived during the reign of Ahuizotl’s nephew, Moctezuma II, who died fighting the invaders. Moctezuma’s brother, who took the throne next, died of smallpox, a disease brought by the Spaniards. The throne passed to Ahuizotl’s son, Cuauhtémoc, who surrendered to Cortés in 1521, only to be tortured for the whereabouts of mostly nonexistent gold and silver. Cortés had Cuauhtémoc, the last ruler of the Aztec Empire, executed in 1525.

Seashells for the war god

By the time Ahuizotl’s son died, Cortés had already destroyed the Templo Mayor and had begun building a Christian cathedral in its place. Archaeologists rediscovered the buried remains of the temple in the 20th century, and they soon found that most of the seventh and final layer was too demolished to learn much from. The last well-preserved layer of the temple was the one Ahuizotl ordered built-in 1487. And that’s where archaeologists discovered the galaxy of starfish that the Aztec priests had once offered to Huitzilopochtli.

The offering had been placed in a round building called the Cuauhxicalco, which might have been where the remains of rulers like Ahuizotl were cremated. It’s in a part of the temple usually associated with Huitzilopochtli, based on historical descriptions and other archaeological finds, so archaeologists suggest that the starfish and other items were probably offerings to the war god.

Along with the starfish, seashells, and pufferfish, the offering included a resin figurine and a female jaguar holding an atlatl (a type of spear-thrower) in one claw.

This find is not the first time archaeologists working at the Templo Mayor site have found starfish among the offerings, but it’s the largest collection unearthed so far. And many of the starfish are larger than their modern descendants because global warming and centuries of harvesting by humans have caused the species to evolve toward a smaller body size.

One starfish, in particular, left behind a fossil-like imprint of not only its shape but its internal structures.

“It was, perhaps, one of the first stars that the Mexica priests placed in the offering, so when receiving the weight of the jaguar and all the elements, it sank into what is believed to be a layer of fibre below it, preserving the mark of its internal structure,” explained INAH in a press release. “This situation is unusual since the remains of the other 163 stars are scattered, due to the natural loss of their organic matter.”

Side note: What’s in a name?

If the name Ahuizotl sounds familiar to you and you’re not a student of Aztec history, you’re probably a My Little Pony fan or a tabletop RPG player. The Aztec ruler took his name from the name of a mythical creature that lived near lakes and in swamps. Reportedly, the creature looked a bit like a dog, except with monkey-like hands (including one at the end of its tail) and spiky fur. It also reportedly killed one of Cortés’ soldiers.

Dungeons and Dragons and Pathfinder both feature swamp-dwelling creatures called Ahuizotl, which bear a passing resemblance to the creature of Mexica legend. And a recurring villain in My Little Pony: Friendship Is Magic was a dog-like, spiky-furred character named Ahuizotl. Now you know.

And knowing, after all, is half the battle.
