The Cambrian period's earliest animals, which occurred half a million years ago, were small enough that they could fit in your palm. A new Cambrian predator, named this week, was half a metre in length. The impressive invertebrate, Titanokorys gainesi was named for reminding us just how much remains to discover in the fossil record of Cambrian living.

The new was described by Joseph Moysiuk and Jean-Bernard Caron, both palaeontologists at the Royal Ontario Museum in Canada.
