>>Half a billion years ago, in the Cambrian Period, most animals were smaller than a person’s little finger. That makes the recent discovery of a marine predator from that time all the more exciting, as the sucker grew to up one foot (30 cm) long.
The creature has been named Cambroraster falcatus, and its fossilized remains were found in the 506-million-year-old Burgess Shale deposit in Canada’s Rocky Mountains. In fact, paleontologists from the Royal Ontario Museum and University of Toronto have unearthed hundreds of Cambroraster fossils over the past few summers, formally describing the animal in a paper that was published this week.<<
