A pathbreaking discovery in Greenland has revealed fossils of 500-million-year-old predator worms, known as Timorebestia or "terror beasts." Probably some of the first carnivorous animals ever, these ancient creatures shed light on the evolution of jawed predators and their relation to prehistoric organisms. The Timorebestia, which could grow over 30cm long, were considered giants in the Early Cambrian era.
