Pedopenna ("foot feather") is a genus of small, feathered, maniraptoran dinosaur from the Daohugou Beds in China. It is possibly older than Archaeopteryx, though the age of the Daohugou Beds where it was found is debated. Some estimates give an Early Cretaceous age, but the latest radiometric dating shows them to be late Middle Jurassic (Callovian) (c.140-168 mya.

- Location: Daohugou Beds, Nei Mongol, China Age: Late Jurassic; Callovian-Oxfordian 160 million years ago Pedopenna is a member of a large group of bird-like dinosaurs called maniraptors and due to the fine sediment in which it was fossilized, it is the oldest feathered dinosaur known. It shows that maniraptors were present in the Jurassic long before Archaeopteryx. Its prominent feature includes long feathers on its legs and feet. Two other dinosaurs shared the same feature: the compsognathid Sinocalliopteryx and the dromaeosaurid Microraptor. Like Microraptor, Pedopenna's leg feathers were long and would have possibly been used to glide as well. With small four-winged dinosaurs with advanced feathers, it seems likely that flight evolved by small arboreal dinosaurs gliding from tree to tree.

- Pedopenna ("foot feather") is a genus of small, feathered, maniraptoran dinosaur from the Daohugou Beds in China. It is possibly older than Archaeopteryx, though the age of the Daohugou Beds where it was found is debated. Some estimates give an Early Cretaceous age, but the latest radiometric dating shows them to be late Middle Jurassic (Callovian) (c.140-168 mya. The name Pedopenna refers to the long pennaceous feathers on the metatarsus; daohugouensis refers to the locality of Daohugou, where the holotype was found. Pedopenna daohugouensis probably measured 1 meter (3 ft) or less in length, but since this species is only known from the hind legs, the actual length is difficult to estimate. Pedopenna is classified as a paravian (Paraves), the group of maniraptoran dinosaurs that includes Aves and their closest relatives.
