MEXICO CITY — Researchers in Mexico say they have found clear evidence of blood cells and tissue fragments including muscle and tendon on 2,000-year-old stone knives.
Mexico’s National Institute of Anthropology and History says the finding clearly corroborates accounts from later cultures about the use of sharp obsidian knives in human sacrifice.
Other physical evidence such as cut marks on human skeletons had previously offered indirect proof of the practice.
The institute said Wednesday that it took a methodical examination using a scanning electron microscope to positively identify the tissues on 31 knives from the Cantona site in the central Mexico state of Puebla. (source)
Archaeologists and anthropologists excavating a site in the south of Chile have uncovered stones that are believed to have been used as tools by humans 14,000 years ago.
Scientists from Universidad Católica de Temuco and Universidad Austral de Chile (UACh) were able to determine these were tools because they exhibit the marking congruent with ancient knives and cutting utensils.
"There are rock detachments from a simple, intentional blow that demonstrate that they were doctored, and that means this is a product of a human being. It lets us postulate that cultural diversity was present in this epoch,” UACh archaeologist Efe Ximena Navarro told El Mostrador.
The discovery occurred near Osorno by accident while paleontologists were studying the fossilized remains of gomphotheres, ancestors of modern elephants presumed to have been hunted by human communities in the area. Read more.
Archaeologists from the Gumilyov Eurasian National University have found a mound, presumably dating back to the Iron age. The tomb of Sarmatian warrior is located near the village of Aidarly in the Akmola region. In the mound, archeologists also found arrowheads, knives, an iron belt badge, ceramic vessels and the bones of sacrificial animals.
Sergazy Saken, Archeological Expedition Leader:
- The body of the middle-class warrior is place with its head towards the south which is peculiar for Sarmatians and dates back to 3rd or 4th centuries BC. The artifacts found in the tomb were placed near the body with two vessels near the head and one vessel near the feet. Here, you can see the peculiarities of the grave artifacts. On the left, you can see earrings but in that time, they were wearing earrings in ears.
