Summary:
A rare 520-million-year-old fossil shaped like a 'squashed bird's nest' that will help to shed new light on life within Earth's ancient seas has been discovered in China by an international research team. The fossil is of a probable ‘chancelloriid’, a group of bizarre, balloon-shaped animals with an outer skeleton of defensive spines.
