Anchiornis huxleyi

Anchiornis huxleyi was a crow-sized paravian dinosaur bearing dense plumage across all four limbs, forming aerodynamic flight surfaces on both its forelimbs and hind legs. Fossil melanosome analysis revealed a striking color pattern: a slate-gray to black body, bold white-and-black barred wing feathers, and a vibrant rufous-red crest atop its head. While its limb anatomy suggests it was primarily a ground runner and agile clamberer among Jurassic forest undergrowth, its extensive wing feathers provided lift for gliding or controlled descents from branches.
