Partially Identified Flying Objects

Trenches Peru Nazca HummingbirdSixteen of the mysterious geoglyphs known as the Nazca Lines depict birds—more than any other type of plant or animal. A team of researchers from Japan recently set out to determine which bird species were rendered in the deserts of southern Peru between 2,400 and 1,300 years ago. They have concluded that one image, previously identified simply as a hummingbird, actually represents a specific type of hummingbird called a hermit, which is distinguished by its long, pointed tail.

 

Trenches Peru Humming BirdTwo geoglyphs were found to show pelicans, and another appears to be a baby parrot. The geoglyph creators must have had a penchant for depicting exotic species, as none of these birds live in the Nazca region. In a number of cases, the avians had features that could not be reconciled with any known bird. “I don’t think all the Nazca bird geoglyphs were modeled on real bird species,” says Masaki Eda of the Hokkaido University Museum. “I think some of them combined the traits of several different birds.”

Trenches Turkey Volcano FootprintTrenches Turkey Volcano CROPPED ORIGINALMore than 50 years ago, human footprints were found preserved in volcanic ash near the Çakallar volcano in western Turkey. Since then, experts have tried to figure out when the eruption that cemented the prints in the earth occurred. Now, a team led by geologist İnan Ulusoy of Hacettepe University has produced a definitive answer. Using dating methods that measure the time since the basaltic lava flow first reached Earth’s surface and the time since external rocks carried by the volcano’s molten magma were last heated, they calculated that the eruption occurred approximately 4,700 years ago.

 

Ulusoy and his team also propose that a recently documented pictograph painted on a boulder at a rock shelter just over a mile from the footprints may be an illustration of Çakallar’s eruption made by Bronze Age people who saw it firsthand. The painting appears to depict a volcanic crater, with red dots that could represent glowing vents and a thick red line that may indicate the lava flow that breached the crater’s edge. Says Ulusoy, “I think what prehistoric people witnessed were relatively mild, low-intensity eruptions that you could watch from a safe distance.” 

Saqqara's Working Stiffs

Trenches Egypt Saqqara BLOCK REVISEDThirty-six mummies dating to between 600 B.C. and A.D. 100 have been discovered by a team of Polish archaeologists in Saqqara, the ancient cemetery of the city of Memphis in Egypt. These mummies received only the simplest embalming, explains excavation director Kamil Kuraszkiewicz, an Egyptologist at the University of Warsaw. “There are no inscriptions or personal items that would hint at these people’s names or professions,” he says, “but analysis of skeletal remains indicates that they mostly performed hard labor.” Of the very few coffins found with the mummies, one was decorated with a nonsensical hieroglyphic inscription and rough depictions of jackals meant to represent Anubis, the god of death. The designs seem to imitate coffins found in high-status burials.

Trenches Italy Cumae TombIn a necropolis at the site of Cumae, near Naples in southern Italy, archaeologists have uncovered a painted tomb dating to the second century B.C. Cumae is the oldest Greek settlement in Italy, founded sometime in the eighth century B.C. It is also the home of the Cumaean sibyl, a prophetess who, like her counterpart at Delphi in Greece, presided over a sanctuary of Apollo. Like the sibyl, Cumae maintained its importance for centuries. It was the home of a large community of non-Latin-speaking local Italic people called Oscans who settled there in the fifth century B.C., and remained influential into the second and first centuries B.C., explains archaeologist Priscilla Munzi of the French National Center for Scientific Research. 

 

The Oscan tomb is constructed of huge blocks of tufa. Unlike the other tombs found in the necropolis, however, whose inner walls are simply plastered, or, at most, plastered and painted white or red, this tomb’s walls are covered with a banquet scene above the entryway and landscapes on the ceiling and sidewalls. Along three walls, there are stone beds for the deceased. The necropolis was eventually abandoned and covered over by an artificial terrace built by the Romans in the first century A.D. and used for military training. 

Home on the Plains

Trenches Bolivia Forest IslandTrenches Bolivia Human RemainsThe earliest known settlements in southwestern Amazonia date to thousands of years before the rise of agriculture in the area. Researchers have found that between 10,600 and 4,000 years ago, hunter-gatherers settled for at least part of the year at sites in an expanse of tropical savanna known as the Llanos de Moxos in northern Bolivia. Led by José Capriles, an archaeologist at Penn State University, the team carried out excavations at three forest islands—wooded areas slightly elevated above the surrounding plains. There they found layers of charcoal, snail shells, and bones of animals ranging from fish and deer to snakes and armadillos.

 

Capriles believes that people spent a portion of each year at the forest islands, most likely during the rainy season when lower-lying areas flooded, and that they came to see the sites as home. In addition to evidence of what people ate, the team unearthed five complete human skeletons encrusted in calcium carbonate that had leached from the soil. The bones were too degraded to be dated, but appear to have been intentionally buried between 7,000 and 6,000 years ago, based on radiocarbon dating of charcoal associated with them. “If your ancestors are buried in a place, you feel a stronger connection to it and can make an argument that it’s yours,” says Capriles. “The burials may also have created a sort of social memory that tied people together in these places.”
