A team of archaeologists were working on an exploration and survey mission off the western coast of Cuba when their sonar equipment picked up a puzzling series of stone structures lying way down below the surface. Is this evidence of a lost civilisation? The structures appeared completely analogous against the barren ‘desert’ of the ocean floor and seemed to show symmetrically organised stones reminiscent of an urban development. Some even claim an ancient sphinx was discovered. What happened to these discoveries?
