A tribute to 3 Dinosaurs all discovered/discovered to have feathers this year, all discovered in china. Packed all into 40 seconds. …
Heres a brief summary and whats so special about these critters:
A small maniraptorian dinosaur known only from one fossil. It lived 152-162 MYA. Its skeleton shows that it had four long tail feathers, and wore a coat of downy fur. The skeleton measures only 10 inches and it weighed about 164 grams. It also had a long bird-like third finger.
A small, feathered, Maniraptorian dinosaur. it is very closely related to birds. It was about 13 inches long and lived during the Jurassic/Cretaceous period. Scientists suggest it could probably fly, as it is very similar to Achaeopteryx.
A tiny Heterodontid Dinosaur of only 70cm (as estimated in the holotype subadult based on Heterodontosaurus.) It is unique because its skeleton shows fragmentary structures that resemble feathers. This confused paleontologists because Heterodontosaurs were once thought to be in no way related to birds, belonging to a group that gave no ancestral link to birds. This strange herbivore lived in the Early Cretaceous, and has small tusks in its mouth. It is also the earliest feathered dinosaur known.

From New Scientist:
Oldest feathered dinosaur is earliest bird

The record for the oldest feathered dinosaur, which has stood for almost 150 years since the discovery of Archaeopteryx, has finally fallen to an even older fossil unearthed in China, shedding new light on the origin of birds.
The first full skeleton of Archaeopteryx, “that strange bird” as Darwin described it, was discovered in the Jurassic limestone of Solnhofen, Germany, just two years after the publication of On the Origin of Species. It has remained something of an evolutionary anomaly ever since.
Spectacular feathered dinosaurs discovered in the last decade or so show clearly how a small group of theropod dinosaurs gave rise to the first birds, but these specimens are almost exclusively Cretaceous in origin, at least 20 million years younger than Archaeopteryx. Feathered dinosaurs pre-dating Archaeopteryx have remained elusive, largely because the Jurassic theropod fossil record is so poor.
The closest palaeontologists have come to a feathered dinosaur older than Archaeopteryx is Pedopenna, discovered in Inner Mongolia in 2005. But there’s some confusion over exactly how old the Inner Mongolian sediments are, and it’s likely that Pedopenna is actually slightly younger than Archaeopteryx.
Four wings good
Not so the new Chinese find Anchiornis huxleyi, the latest of a number of specimens found in the past year and the first to sport feathers. It comes from the Tiaojishan formation of Jianchang county, recently dated to between 161 and 151 million years old and therefore older than the 150-million-year-old Archaeopteryx-bearing German rocks.
Anchiornis possesses well-developed feathers on all four limbs, a trait that would have seemed bizarre if the fossil had been discovered a decade ago. But palaeontological finds in recent years suggest the four-wing pattern may have been the rule rather than the exception in proto-birds – both Microraptor, discovered in 2003, and Pedopenna have feathered hind limbs.
