1 . Human faces cut into stone up to 2,000 years ago have again been found on a rocky area along the Amazon River in northern Brazil. The stone carvings (雕刻品) appeared as a result of a big drop in water levels because of dry weather in parts of northern Brazil. The water level had dropped to the lowest level in the history of the river.
“People had reported some of the stone carvings before during periods when water levels were low. But now a greater number have been identified. That will help researchers establish the history of the carvings, and more secrets of historical relics will come to light,” researcher Jaime de Santana Oliveira said recently.
One area shows smooth marks in the rock thought to be where natives once sharpened their tools such as arrows and spears before European settlers arrived.
“The carvings are prehistoric, or precolonial (殖民地时期前的). We can’t be sure of their precise date but based on the evidence of human living places of the area, we believe they are about 1, 000 to 2, 000 years old.” Oliveira said.
The rocky area is on the north shore of the Amazon River near the place where the Rio Negro River joins it.
Oliveira said the carvings were first seen in 2010, but this year’s drought has been more serious than earlier dry periods. The Rio Negro’s levels have dropped 15 meters since July, uncovering large areas of rocks and sand where there had been no beaches.
“This time we found not just more carvings, but the statue of a human face cut into the rock,” said Oliveira, who works for the Brazilian government’s National Historic and Artistic Heritage Institute. The organization watches the care of historic places in Brazil.

3 . Macaques don’t use the sharp flakes they create for anything, Luncz adds, noting that the monkeys have sharp teeth and don’t need cutting tools. The similar ancient stone tools collected from some of the earliest known sites, however, show evidence of being used for cutting tasks. For example, in Oldowan, a site dating between 3.3 million and 1.5 million years ago, researchers analyzed use-wear patterns on the tools and found that some of the flakes showed damage along their edges, indicating that they had been used for cutting. Cut marks on some fossils revealed that hominins had used stone tools for butchering the animals, making it clear that the sharp stone tools were anything but unintentional by-products of other pounding activities.

7 . Archeologists said on Wednesday they have unearthed the oldest wooden structure ever discovered, dating from nearly half a million years ago, which suggests that our ancestors may have been more advanced than previously thought.
The exceptionally well-preserved wooden structure was found at Kalambo Falls in the north of Zambia near the border with Tanzania. It dates back at least 476,000 years, well before the evolution of Homo sapiens (智人), according to a study describing the find in the journal Nature.
The wood bears cut-marks showing that stone tools were used to join two large logs to make the structure, which is believed to be a platform, walkway or raised dwelling to keep our ancestors above the water. A collection of wooden tools, including a wedge and a digging stick, was also discovered at the site. The ancestors of humans were already known to use wood at this time, but for limited purposes such as starting a fire or hunting.
Larry Barham, an archeologist at the U. K.’s University of Liverpool and the study’s lead author, said the structure was a “chance discovery” made in 2019 while excavating the site located on the banks of the Kalambo River, above a 235-meter waterfall.
Discoveries involving such ancient wood are rare, because it tends to rot leaving behind little trace for the historical record. But the high level of water at Kalambo Falls is believed to have preserved the structure over the centuries.
Excavations at the Kalambo site in the 1950s and 1960s unearthed some wood, but it was not able to be accurately dated. However, this time around, the researchers used a new method called luminescence dating, which determines age by measuring the last time certain minerals were exposed to sufficient heat or sunlight. This revealed that the structure was much older than the researchers had thought, dating back at least 476,000 years.
The discovery of the wooden structure “changed how I thought about these people”, Barham added. “They transformed their surroundings to make life easier, even if it was only by making a platform to sit on by the river to do their daily chores,” he said. “They used their intelligence, imagination and skills to create something they’d never seen before, something that had never previously existed.”

8 . Lisa St. Coeur Cormier, a high school science teacher in Prince Edward Island (PEI), Canada, found a tree root. When she took a closer look, she found the shape was very strange. She realized it wasn’t a tree root though it shared the same color. She felt it was hard to break and noticed an impression of bones of what looked like some kind of animal.
Cormier sent a photo of the find to Laura MacNeil who used her knowledge in this field to confirm that what Cormier had seen really was a fossil (化石). MacNeil runs tours of sites where prehistoric fossils have been found and also helps people identify fossils. She visited the site of Cormier’s find to take more photos of it.
MacNeil contacted John Calder, a scientist, who examined the fossil and led a team of scientists to study it. John Calder said it could be as much as 300 million years old. He said it’s probably from a reptile (爬行动物) of some kind — likely one that is unknown to scientists. Scientists spent 5.5 hours carefully digging out the fossil from the ground so they could study it more in-depth and find out exactly what kind of animal it is. That research could take a year or more.
“This is an important discovery here on Prince Edward Island. It is the second of the only two articulated skeletons (关节相连的骨头) found on PEI,” Laura MacNeil said. “This creature lived about 300 million years ago. This find tells us there is a great possibility for future scientifically important fossils that could be discovered on PEI. It will lead to more researchers paying a visit.”
