Back in 1969, a very unusual observation was made by a team of construction workers from Oklahoma. What appears to be a huge antediluvian structure was seen by the manual laborers when they had evidently been able to date back to 200,000 years ago.
It was publicly published in the daily newspaper known as The Oklahoman, which referred to it as the “Old Mosaic Floor.”
This mosaic floor was said to have been set in precisely parallel lines, intersecting into a diamond formation, according to Durwood Pate, a local geologist at the time.
At first, the team of geologists agreed that this must be a natural discovery, but this was soon denied by Delbert Smith, president of the Oklahoma Seismograph Company, who argued that the whole structure was ideally expanded to several thousand square feet and that it was perfectly symmetrical along the way.
Interestingly enough, the mosaic floor also seemed to contain aquatic sediment, which showed that, at some point, the position itself was totally submerged underwater.
But that’s not all, because, in the same place, experts also came across an iron cup inside a piece of coal dating back to 300 million years ago. This finding was officially made by Frank J. Kennard, who claimed that he had broken a piece of coal himself with a sledgehammer.
