Microraptor was a small, feathered dinosaur that occupied the forested wetlands of early Cretaceous China. About the size of a raven, it had large feathers on its arms and legs. Despite its bird-like appearance, Microraptor also had several features typical of dinosaurs, including rows of sharp teeth, claws on its hands, and a long, bony tail. This species helped prove that dinosaurs and birds are closely related.
History
Microraptor belongs to a group of ‘raptor’ type dinosaurs, more properly known as dromaeosaurids. This group includes Velociraptor and Sinornithosaurus. The discovery of this feathered species has drastically changed our understanding of the appearance of ‘raptor’ dinosaurs.
Many Microraptor fossils preserve both the animal’s bones and feathers. The feathered, wing-like arms of Microraptor were suitable for gliding flight. Its wing feathers had a central vane and an asymmetrical shape, just like the feathers in modern flying birds.
This dinosaur may have used its sharp claws to scramble up the trunks of trees, and then leaped from the canopy, gliding from tree to tree. Microraptor lived in a forested wetland ecosystem known as the Jehol. The Jehol ecosystem was very rich and Microraptor was an opportunistic hunter, feeding on a diverse range of prey such as insects, lizards, and fish. The species was first named in 2000, with its name literally meaning ‘tiny thief’.
