Three-Fingered DinosaurCredit: Portia SloanThe fossilized hands from this plant-eating dinosaur reveal a transitional step in the evolution of modern wings from dino digits. The finding could resolve a debate over which fingers ultimately became embedded in the wing. This dinosaur, Limusaurus inextricabilis, may have used its three-fingered hands to help it stand upright from a lying position.
A pigeon-sized, four-winged dinosaur known as Microraptor had black iridescent feathers when it roamed the Earth 130 million years ago, according to new research led by a team of American and Chinese scientists that includes Museum researchers. The dinosaur’s fossilized plumage is the earliest record of iridescent feather color.
