A pioneering three-dimensional, virtual reality look at outcrop earlier described as having signs of 3.7 year-old stromatolite life, which would be the oldest remnant of life On earth. The cuts in the main surface were made by two teams studying the rock in great detail to determine whether the reported stromatolites — built up layers of micrbial biofilms and sediments — are actually present.
