    Measuring the Invisible Wake of a 500 million-year-old Swimmer

    With this perspective we see the tail-fin model of Anomalocaris Canadensis, a 500 million-year-old predator from the Burgess Shale, as it passes through the high-speed laser sheet. Not visible on either side are high-speed cameras that capture the motion of millions of tiny silver-coated, hollow-glass spheres that track the flow. By tracking the motion of these tiny spheres we reconstruct the otherwise invisible wake of this ancient swimmer. This fin shape is unique from that period but may serve as a good model for high-performance aerodynamic control surfaces today.
