Microraptor and fern forest

A feathered dromaeosaurid dinosaur of the genus Microraptor alights atop a tree fern 120 million years ago in what is today Liaoning, China.

Like the earlier Archaeopteryx, Microraptor was about size of a modern European Magpie and is one of smallest dinosaurs ever discovered. Microraptor's entire body was covered with feathers including a broad stabilizing tail and elongated feathers for flying on both its arms and legs, leading to its classification as a four-winged dromaeosaur.
