In 1945 the excavation of a 2,000-year-old Native American burial site led to a very strange discovery and now analysis has been able to confirm that the materials that had been used to make the objects did not come from Earth.
Space Rock Crashed On Earth And Shards Used To Make Beads
Archaeologists were excavating the grave in Illinois in the USA in 1945 and came across 22 metal beads that had been made from meteorite shards. Since that time scientists have thought about the identity of the space rock that seemed to have crashed on Earth that had been responsible for the fragments.
Now there is strong evidence from a new study that links them to the Anoka meteorite which came to Earth around 700 kilometers from the dig in Minnesota. Experts have said that the metal beads, which were crafted intricately, may belong to one of the members of the Hopewell culture, which were recognized by the earthen mounds that were elaborate and for using alien materials.
Anoka Meteorite May Have Been The Source Says Recent Analysis
Even though prior studies had said that the Anoka meteorite was not the source, more recent analysis of a piece of the meteorite, which was found in 1983, has provided evidence that is convincing of the progenitor of the shrapnel that aborigines used to elaborate the items.
Scientists made use of mass spectrometry to reach the conclusion; this is an analytical technique ionizing chemical species and separates the iron based on the mass-to-change ratio. The scientists discovered that the beads used in the necklace and the meteorite fragment had the same composition, meaning that both had small pieces of iron that were enriched with nickel.
Meteoric Metal Used In Hopewell Beads Most Exotic Raw Material Used
The authors of the study went on to talk about the meteoric metal, the iron that was in the Hopewell beads, being the most exotic raw material that had been used in Eastern North America in the Middle Woodland period. They went on to say that there were similarities in minor, major and trace element chemistry in the Havana and Anoka, there was micrometer sized gamma iron in kamacite in both of them and there was a connection that was obvious through the Illinois River and the Mississippi River between Havana and Anoka, which points to production of the Havana beads from the mass of Anoka iron.
The experts said that the meteorite included traces of schreibersite, which is a mineral that is fragile, so it would have broken into small metal pieces. There was support for this when scientists tried to copy the manufacturing process in the laboratory.
The curator of the National Museum of Natural History, Timothy McCoy, said that 2,000 years ago ideas along with goods had been taken many hundreds of miles over eastern North America. Experts have the belief that the iron that was used to make the beads had been collected by locals, who then exchanged it to the Havana Hopewell center and they manufactured it.
Ancient Civilizations Made Crafts And Weapons In Africa From Meteorites
What is interesting is that similar discoveries had been located many thousands of kilometers away over in Africa; again ancient civilizations had used fragments from meteorites to make weapons and crafts. Scientists found that ancient Egyptians had made use of fragments that came from meteorites and made weapons for the elite that ruled at the time.
It was said that the ancient Egyptians knew about the origins of metal from other worlds and they wrote frequently about metals that had come down from the heavens in texts.
Researchers from prior studies had written the celestial or the terrestrial origin of iron from ancient Egypt along with when the use of it become common are issues that are contentious and which are debatable. They went on to say that evidence has been gathered from many areas, including language, belief and architecture.
So it does look as though ancestors dating back many hundreds of thousands of years may have used alien materials to make trinkets and weapons.
