Archaeologists in Italy recently unearthed the remains of at least nine Neanderthals in Guattari Cave, near the Tyrrhenian Sea about 100 km southeast of Rome. While excavating a previously unexplored section of the cave, archaeologists from the Archaeological Superintendency of Latina and the University of Tor Vergata recently unearthed broken skulls, jawbones, teeth, and pieces of several other bones, which they say represent at least nine Neanderthals. That brings the cave’s total to at least 10; anthropologist Alberto Carlo Blanc found a Neanderthal skull in another chamber in 1939.

Italy was a very different place 60,000 years ago. Hyenas, along with other Pleistocene carnivores, stalked rhinoceroses, wild horses (an extinct wild bovine called aurochs), and people.

“Neanderthals were prey for these animals. Hyenas hunted them, especially the most vulnerable, like sick or elderly individuals,” Tor Vergata University archaeologist Mario Rolfo told The Guardian. The archaeologists found the Neanderthal remains mingled with the bones of rhinos, giant deer, wild horses, and other hyenas. Predators and scavengers tend to leave behind different parts of the skeleton than, say, flowing water or simple burial—and tooth marks are usually a dead giveaway.

CT scans of a mummified Egyptian pharaoh, once suspected to be the victim of a palace assassination, suggest that he was actually executed after being captured in battle in the mid-16th century BCE.

Pharaoh Seqenenre led his army from Upper Egypt in the 1550s BCE to face the Hyksos, a group of warriors from the Levant who occupied Lower Egypt and demanded tribute from Upper Egypt during what historians call the Second Intermediate Period. It’s known that Seqenenre died during this conflict, but it’s been unclear whether he was assassinated in his bed in the palace at Thebes or died on the battlefield.

A computed tomography (CT) scan offered a look at his wounds, along with the details of his mummification. Radiologist Sahar Saleem of Cairo University and former Egyptian Minister of Antiquities Zahi Hawass concluded that he most likely died near the front lines and was brought back to Thebes for mummification and burial.

After 18,000 years of silence, an ancient musical instrument played its first notes. The last time anyone heard a sound from the conch shell trumpet, thick sheets of ice still covered most of Europe.

University of Toulouse archaeologist Carole Fritz and her colleagues recently recognized the shell as a musical instrument. To understand more about how ancient people crafted a trumpet from a 31cm (1 foot) long conch shell, the archaeologists used high-resolution CT scans to examine the shell’s inner structure: delicate-looking whorls of shell and open chambers, coiled around a central axis, or columella. A series of overlapping photographs and careful measurements became a full-color, 3D digital model of the shell, and image enhancement software helped reveal how Magdalenian people had decorated the instrument with red ocher dots.

And in a lab at the University of Toulouse, a horn player and musicology researcher became the first person in 18,000 years to play the conch shell. The musician blew into the broken tip, or apex, of the shell and vibrated his lips as if he were playing a trumpet or trombone. Very carefully, he coaxed three loud, clear, resonant notes from the ancient instrument:

Last month, archaeologists in Mexico City unearthed the eastern façade of a tower of skulls near the 700-year-old site of the Templo Mayor, the main temple in the former Aztec capital city of Tenochtitlan. It’s a morbidly sensational find, but it’s also a potential treasure trove of information about the people who died at Tenochtitlan in the city’s final centuries. Here’s what the skulls in the tower could tell us if we ask them—and why we'd have to ask very carefully.

Archaeologists found 119 skulls built into the structure, a morbid addition to the 484 skulls found on the northeast side of the tower, which archaeologists rediscovered in 2015. Since 2015, excavations have reached 3.5 meters below modern street level, into the layers of ground once trod by Aztec priests, onlookers, and sacrificial victims. From those excavations, we now know that the 4.7 meter (15.4ft) tall tower was built in at least three phases, starting in the 15 ^th century.

The nearby Templo Mayor once housed important shrines to the war god Huitzilopochtli and the rain and farming god Tlaloc. Many of the victims sacrificed to the two gods probably ended up as building blocks for the tower, properly known as the Huei Tzompantli, nearby. A tzompantli is a wooden scaffold for displaying skulls (exactly as the name suggests if you happen to speak Nahuatl; the word means something along the lines of “skull rack” or “wall of skulls”). The temple district of Tenochtitlan once boasted at least seven of them.

Indigenous Pueblo populations in the American Southwest—ancestors of today's Hopi, Zuni, and Rio Grande Pueblo tribes—typically wove blankets, cloaks, and funeral wrappings out of animal hides, furs, and turkey feathers. Anthropologists at Washington State University (WSU) have examined one such ancient turkey-feather blanket and determined it took thousands of those feathers, wrapped around nearly 200 yards to yucca fiber, to make, according to a new paper published in the Journal of Archaeological Science: Reports.

"Blankets or robes made with turkey feathers as the insulating medium were widely used by Ancestral Pueblo people in what is now the Upland Southwest, but little is known about how they were made because so few such textiles have survived due to their perishable nature," said co-author Bill Lipe , emeritus professor of anthropology at WSU. "The goal of this study was to shed new light on the production of turkey feather blankets and explore the economic and cultural aspects of raising turkeys to supply the feathers."

For their study, Lipe and his WSU colleague and co-author, Shannon Tushingham, studied a blanket framework on display at the Edge of the Cedars State Park Museum in Blanding, Utah. Although insects had devoured the original feather vanes and barbs, the shafts were still visible, wrapped around yucca fiber cords. They were also able to look at a second, smaller blanket which still had most of its feathers intact. Both blankets roughly date to the early 1200s CE.

Archaeologists are fascinated by many different aspects of cultures in the distant past, but determining what ancient people cooked and ate can be particularly challenging. A team of researchers spent an entire year analyzing the chemical residues of some 50 meals cooked in ceramic pots and found such cookware retained not just the remnants of the last meal cooked, but also clues as to earlier meals, spanning a pot's lifetime of usage. This could give archaeologists a new tool in determining ancient diets. The researchers described their results in a recent paper published in the journal Scientific Reports.

According to co-author Christine Hastorf , an archaeologist at the University of California, Berkeley (UCB), the project has been several years in the making. Hastorf has long been interested in the relationships between people and plants throughout history, particularly as they pertain to what people ate in the past. Back in 1985, she co-authored a paper examining the isotopes of charred plant remains collected from the inside of pots. She has also long taught a food archaeology class at UCB. A few years ago, she expanded the course to two full semesters (nine months), covering both the ethnographic aspects as well as the archaeological methods one might use to glean insight into the dietary habits of the past.

The class was especially intrigued by recent molecular analysis of pottery, yet frustrated by the brevity of the studies done to date on the topic. Hastorf proposed conducting a longer study, and her students responded enthusiastically. So they devised a methodology, assigned research topics to each student, and located places to purchase grain (maize and wheat from the same region of the Midwest), as well as receiving venison in the form of donated deer roadkill. She even bought her own mill so they could grind the grains themselves, setting it up in her home garage.

The ancient Egyptians mummified animals as well as humans, most commonly as votive offerings to the gods available for purchase by visitors to temples. Many of those mummified remains have survived but are in such a fragile state that researchers are loath to disturb the remains to learn more about them. Now an inter-disciplinary team of scientists has managed to digitally "unwrap" three specimens—a mummified cat, bird, and snake—using a high-resolution 3D X-ray imaging technique, essentially enabling them to conduct a virtual postmortem, according to a new paper published in the journal Scientific Reports.

Studying fragile ancient artifacts with cutting-edge imaging technology confers a powerful advantage on archaeological analysis. For instance, in 2016, an international team of scientists developed a method for "virtually unrolling" a badly damaged ancient scroll found on the western shore of the Dead Sea, revealing the first few verses from the book of Leviticus. The so-called En Gedi scroll was recovered from the ark of an ancient synagogue destroyed by fire around 600 CE.

In 2019, we reported that German scientists used a combination of cutting-edge physics techniques to virtually "unfold" an ancient Egyptian papyrus, part of an extensive collection housed in the Berlin Egyptian Museum. Their analysis revealed that a seemingly blank patch on the papyrus actually contained characters written in what had become "invisible ink" after centuries of exposure to light. And earlier this year, we reported that scientists had used multispectral imaging on four supposedly blank Dead Sea Scrolls and found the scrolls contained hidden text, most likely a passage from the book of Ezekiel.
