A farmer in Poland has uncovered weapons dating back thousands of years. Jarosław Lipiec was plowing his fields when he came across the head of a large flint axe and spearhead that he handed over to the Lublin Provincial Conservator of Monuments. Museum officials said the gray-colored objects were parts of a tetrahedral axe, probably created by Neolithic people around 5,000 years ago.
The spearhead was almost entirely preserved and comes either from the Mierzanowice culture or the Trzciniec culture that date back to between 1900 and 1500 BC. Historians and archaeologists previously believed that the region, around 140 miles from Warsaw, had no historic inhabitants but have now been forced to review that position. Further research will be carried out in the coming weeks.
The finds are exciting to archeologists, but in terms of age, they are still relatively young compared to the oldest artifacts on record. For example, the oldest known manufactured objects yet discovered are the Lomekwi stone tools – estimated at more than 3 million years old. Not much is known about the relics found in Kenya in 2015, but experts believe they were used by ancestors who pre-date the Homo genus species that would eventually evolve into modern-day human beings.
The oldest artifacts found in the United States are housed at the Center for the Study of the First Americans at Texas A&M University and include spearheads, blades, and projectile points that are believed to be around 15,000 years old.
Australia is home to the oldest single object human beings have yet discovered – these are the zircon crystals found in the Jack Hills in the state of Western Australia. Geologists say they date back almost 5 billion years and suggest that the Earth was not as inhospitable as previously thought.
Elements in the crystals indicate they came from water-rich rocks, leading scientists to believe there was surface water on the planet relatively soon after it came into being.
