      Is it the lost Atlantis?

      Traces of prehistoric supercontinent discovered off the coast of BrazilIt’s not the legendary Atlantis, but researchers are claiming to have found traces of a long-lost continent buried in the Atlantic Ocean near Brazil. The researchers announced on Tuesday that samples of rock from the site appear to be remnants of Pangea, the prehistoric supercontinent from which the Americas, Africa, and other present-day land masses eventually emerged.

      A Brazilian-Japanese team that included researchers from the Brazilian Geological Survey, the Oceanographic Institute of Sao Paolo, and Japan’s Agency for Marine-Earth Science and Technology found the rocks during an expedition to study the Rio Grande Elevation, a high-rising mass of ocean floor about 930 miles from the shore of Rio de Janeiro. Over a month of study, the team examined the formation up close through a series of dives in a three-person submersible craft to as far down as 21,000 feet below the surface.

      It was on these dives that the team noticed that the rock’s composite minerals included granite, iron, and cobalt, none of which were present in the surrounding seabed. The granite was a particularly noteworthy find, since this rock usually only appears on land.

      The researchers drilled into the rock and extracted a few samples, which they brought samples up to the surface and subjected to deeper chemical analyses. They now hypothesize that the rock may have been an island that existed alongside Pangea...when the land masses that would become South America and Africa started breaking off of the supercontinent. The island may have gotten caught in between these fissures and pulverized into the ocean floor.

      Roberto Ventura Santos, director of the Brazilian Geological Survey, and other observers have already dubbed this theoretical island “Brazil’s Atlantis,” in allusion to the island of ancient Greek lore. However, this real-life island would presumably have disappeared beneath the waves millions of years before there were any Greeks...to see it and write tributes to it.

      No one expects to find any ancient cities within this granite, but Santos does suggest that the rock’s discovery may have significant implications for our understanding of the formation of the continents...

      The team is now gathering samples of rock previously found in other portions of the southern Atlantic for cross-comparisons. It expects to return to the Rio Grande Elevation and conduct further drilling along the site later this year.

        Image showing how all the continents fit together.Referring to the article on the alleged prehistoric ancient super continent,  Cartographers have fit all the Americas' eastern coastlines like a jigsaw puzzle exactly to Europe and Africa's western coastlines, and these combined continents along with all other continents, once joined together  were known as the "Pangaea."

        This, not counting  the  land strip  known as  the Continental  shelves, the continent's shores which extend a few miles out under the sea, then drop sharply off like a torn piece of cake to some 13,000 feet and more in places;  and where the mid-Atlantic ridge itself is the actual mid point  or 'fissure of this separating "pushup."  There is/was no space where there could ever have been a continent or very long island between these two continents at any time. 
        Socrates' Dialogues (called Plato's Dialogues) gives the exact areas and names of the lands the fabled sea-faring "Atlanteans" actually occupied, as does Herodotus. The ancient sailor's way to the Americas was secretly  hidden within these Socrates' dialogues and  are very clearly in plain view, which I believe to be the actual bottom-line of the story.  Socrates was also warning the King of Greece, i.e. Macedonia of an impending battle planned by  the "then Atlanteans."     :-)
