In his book Wonderful Life, the late Stephen Jay Gould, former professor in the Department of Organismic and Evolutionary Biology at Harvard, popularized the “weird wonder” stem-group arthropods Opabinia and Anomalocaris, discovered in the Cambrian Burgess Shale, turning them into icons in popular culture. While the “terror of the Cambrian’ Anomalocaris—with its radial mouth and spiny grasping appendages—is a radiodont with many relatives, the five-eyed Opabinia—with its distinctive frontal proboscis—remains the only opabiniid ever discovered. That is, until now.
