This fossil is a pair of claws from Anomalocaris canadensis, the largest Cambrian predator reaching lengths up to three feet, and the first of its type to be discovered at the Stanley Glacier site, by Caron and crew. Among its distinctive features, this animal had a pair of large eyes at the front and a rounded mouth with sharp teeth.
