Waptia fieldensis Walcott, 1912 is an iconic animal from the middle Cambrian Burgess Shale biota in British Columbia that had lacked a formal description since its discovery at the beginning of the 20th century. Drawing on some 1,800 specimens, researchers three-dimensionally reconstructed the ~508-million-year-old animal’s functional anatomy. The shrimp-like animal’s compound eyes, antennae, mandibles, and swimming and breathing appendages shed light on the early evolution of mandibled arthropods and crustaceans.
