Tiny imprints in the feathers of fossilized dinosaurs have alternately been attributed to both melanosomes—pockets of melanin—and bacteria. Previous studies suggested that the imprints discovered in ...

From the colors of dinosaurs’ eggs and feathers to the shapes of their brains, our dino encyclopedia now includes unprecedented details on how these animals were born, grew up, and lived.

Prior research has shown that patterns in melanosomes can be used to determine feather, fur, or skin coloring. This has led other research teams to learn about the coloring of many types of dinosaurs.

But there is one natural wonder that just about all of us can see, simply by stepping outside: dinosaurs using their feathers to fly. Birds are so common, even in the most paved-over places on ...

Over the last two decades, dozens of fossilized dinosaur remains bearing evidence of feathers or quill-like protofeathers have surfaced, most notably among ornithischians and coelurosaurian theropods.

Researchers inhibited a gene during embryonic development in chickens to see if it would make their feathers look like those of dinosaurs. Here, we see feather buds on the 12th day of incubation.
