In different parts of the world, artefacts are found that raise questions from historians and archaeologists, since they do not correspond to the generally accepted version of the development of human civilisation. One of these mysteries is a strange structure in the form of a mosaic floor, found in 1969 during construction work in the US state of Oklahoma.
"Mosaic" was found in a layer formed, according to expert opinion, 200,000 years ago. Moreover, it is believed that the first people settled in North America only in the period from 19 to 22 thousand years ago. Then the publication about the find appeared in the local newspaper The Oklahoman. It was accompanied by several black and white photographs. The article said: "On June 27, 1969, workers cutting through a rock located on the Broadway Extension of 122nd Street, between Edmond and Oklahoma City, stumbled upon a find that caused much controversy among experts. To the layman, this place looked like a mosaic floor laid out from pieces of stone".
The author of the note also cited the opinions of some experts about the mysterious find. For example, independent petroleum geologist Durwood Pate argued that the mosaic was man-made: "I'm sure it was man-made because the stones were arranged in perfect sets of parallel lines that intersected to form a diamond shape, all pointing east. We also found a hole for a pole which is perfectly level."
Pate agreed with his colleague, the president of the Oklahoma Seismograph Company and ex-president of the Oklahoma City Geophysical Society, Delbert Smith , who arrived with him at the find site to take samples . He told the newspaper that the structure was about 90 centimeters below the ground and was supposed to cover an area of several thousand square feet. Examination of the samples showed that the "mosaic" consisted of Permian limestone with an admixture of quartz grains.
In turn, Dr. Robert Bell , an archaeologist from the University of Oklahoma, considered this to be a natural formation, since he did not see any traces of a processing agent that must have been used to create a mosaic (by the way, Pate claimed to have found traces of grout between the "tiles"). On July 1, 1969, The Oklahoman reported that a second "mosaic" hole had been discovered. Both holes were located at a distance of 5 meters from each other.
According to a publication in The Oklahoman newspaper on July 3, an object resembling an "ancient stone hammer" was found near the "mosaics". Another local geologist, John M. Ware, said: "It's simply impossible to explain within the field of geology - we need an archaeologist to give a final opinion."
It is curious that the composition of the rock, inside which the "mosaic" was hidden, included marine sediments. According to experts, once in ancient times it was the bottom of the ocean. Maybe this is the answer? But what if the "mosaic" is the work of representatives of some underwater civilisation?
But, one way or another, the study of the "Oklahoma mosaic" for some reason soon died out. Although this place quickly turned into a tourist attraction. People strove to tear the stone from the rock and take it with them. - Pravda.ru
