Preserved for 70 to 85 million years, these feathers are part of a newly revealed trove of likely dinosaur and bird plumage found trapped in amber in Alberta, Canada.
The unusual find suggests a wide array of plumed creatures populated the time period—sporting everything from seemingly modern feathers to their filament-like forebears—and that even by this early date, feathers had become specialized, for example, for diving underwater, a new study says.
