Paleontologists have figured out what ancient dino feathers and fuzz looked like, including color.
Instead of digging through rocks and rubble to find fossils, a group of Canadian paleontologists decided to dig through museums’ amber collections instead. Their unique approach paid off when they discovered feathers and never-before-seen structures, which they think are something called dinofuzz.
The researchers combed through thousands of minuscule amber nuggets from nearly 80 million years ago. Among them they found 11 M&M-sized globules with traces of ancient feathers and fuzz. A number resembled modern feathers—some fit for flying and others designed to dive. And unlike fossils, the amber preserved colors too: white, gray, red and brown.
But a few hollow hair-like structures stumped researchers. The unidentifiable filaments weren’t plant fibers, fungus or fur, so the researchers surmise that they are protofeathers (thought to be the evolutionary precursors to feathers). The collection is among the first to reveal all major evolutionary stages of feather development in non-avian dinosaurs and birds.
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.
