The remains of what may be a 6000-year-old city immersed in deep waters off the west coast of Cuba was discovered by a team of Canadian and Cuban researchers. Offshore engineer Paulina Zelitsky and her husband, Paul Weinzweig and her son Ernesto Tapanes used sophisticated sonar and video videotape devices to find “some kind of megaliths you ‘d find on Stonehenge or Easter Island,” Weinzweig said in an interview.
