Dilong is not the first tyrannosaur found in the Liaoning fossil beds, and it is more primitive than all other tyrannosaurs found in the world thus far.
Dilong's protofeathers and the fact that living birds vary widely in their skin covering suggest that the appendages of large advanced tyrannosaurs might have been both scaly and feathered.
The work on Dilong paradoxus was funded by the Special Funds for Major State Basic Research Projects of China, the National Natural Science Foundation of China, the National Geographic Society, the Chinese Academy of Sciences, the National Science Foundation of the USA, and the American Museum of Natural History.

  Dilong paradoxus - Wikipedia, the free encyclopedia
Dilong paradoxus ("Emperor Dragon paradox") is a small, feathered tyrannosaurid dinosaur species from the Lower Cretaceous Yixian Formation in the Liaoning province of China, and is around 130 million years old.
It is one of the earliest and most primitive known tyrannosaurids, and had a covering of feathers.
Dilong was about 1.6 m in length and is known from four moderately complete skeletons.

 Dilong - Wikipedia, the free encyclopedia
There is also an article on the feathered dinosaur, Dilong paradoxus.
In Chinese mythology, Dilong or Ti-Lung (地龍; pinyin : dì lóng) are earth dragons whose task it is to preside over rivers and streams.
According to some accounts, they are the female counterpart of the Shenlong and they fly only in order to mate.

 New Dinosaur Discovered
Dilong derives from words meaning "emperor" and "dragon." Paradoxus refers to the unusual feathers found on the 5-foot-long (1.5-meter-long) carnivore.
The description of Dilong paradoxus is based on the fossils of four specimens, including a fragmented one with evidence of protofeathers—precursors to the feathers found on modern birds.
Nevertheless, unlike more advanced tyrannosaurids, Dilong had relatively long forearms with three fingers.The fragmented fossil went unidentified until a more complete fossil of the same creature was studied and found to match the morphology, or form and structure, of that found in the earlier fragments.

Dilong had features common to many more primitive theropods—the group of dinosaurs most closely related to birds—such as a hand with three fingers (most tyrannosaurs’ hands had just two fingers) and a relatively small body (it was just five feet long).
And in late 2004, when the first specimens of Dilong were described, they corroborated a hypothesis that at least some tyrannosaurs had what might be the most superficially obvious bird trait of them all: feathers.
Although it was a little surprising to discover that Dilong had feathers, it was far less surprising that the feathers were of the primitive type.

paradoxus was small and slender: of the four sets of remains found, the longest measures only about 1.6 meters from nose to tail, while the other three are just 1.5 meters.
The creature had the characteristic powerful rear legs and ferociously sharp teeth that made the T. rex the master of its world for 20 million years, a reign that ended with the disappearance of the dinosaurs some 65 million years ago.
For example, D. paradoxus' arms were longer in proportion to its body than those of its monster-size descendant, and it had a long, dragon-like snout.

A 1.5-metre skeleton with traces of protofeathers found in 2001 is now also thought to be a Dilong paradoxus.
We added Paradoxus to its name because it's so counter-intuitive to think of feathers and a Tyrannosaurus together.
Dilong's protofeathers are not what we would recognise as feathers today, but are their evolutionary precursors.

 Guardian | Dinosaur's fluffy coat of feathers
Dilong paradoxus - its generic name comes from the Mandarin for emperor and dragon, and its species name from its unusual features - was the size of a turkey, had a single nose bone, a massive jaw, a long neck, and hands with three fingers.
Dilong is the most primitive of the tyrannosaurid family found so far.
But what shook the discoverers was that the region's unique volcanic ash and sandy muds preserved not just the skeleton but also some soft tissue - and the first direct evidence that tyrannosaurs had feathers, or at least branching structures an inch long called protofeathers.

Norell, a curator and chair of the division of paleontology at New York's American Museum of Natural History, said the discovery supports theories that dinosaurs were birdlike, warm-blooded creatures that evolved feathers to stay warm—not to fly.
Dilong derives from Mandarin words meaning "emperor" and "dragon." Paradoxus refers to the unusual feathers found on the 5-foot-long (1.5-meter-long) carnivore.
Thomas Holtz, a vertebrate paleontologist at the University of Maryland in College Park, was among the group of paleontologists to predict that early tyrannosaurids had feathers.

 TurboAwesome.com - It's quiet... too quiet.
The long standing debate over weather or not the dinosaurs evolved into birds had a new twist yesterday when Nature.com columnist Zeeya Merali reported a fossilized specimen of Dilong paradoxus, the oldest member recorded from the tyrannosauroid family, was found in china with feathers.
The bird theorists claimed a great victory with the discovery stating this is another piece of undeniable proof that dinosaurs had direct ancestral connection to birds.
On the other hand those who oppose the theory are claiming these findings prove Dilong had absolutely no connection to birds, and that bird evolved from their own completely isolated bloodline.

 T. rex's smaller ancestor was covered with down / 130-million-year-old fossils are found in northeast China
The curious features of the primitive little tyrannosaur, some 130 million years old, should provide fresh insights into the evolution of the tribe as the animals became larger and larger, before the ultimate T. was driven to extinction some 65 million years ago along with all the world's other dinosaurs.
But by the time T. rex had evolved from its ancestral tyrannosaurs like Dilong, it's possible that the huge animals no longer needed true feathers as adults -- and instead were covered with scales because they needed to dump excess heat from their big bodies, very much the way elephants do today, Norell said.
And although Dilong's skull was shaped very much like its descendant's, he said its curious forelimbs were surprisingly longer in relation to its body than the stumpy forelimbs of T. rex.

 Feather
One theory is that feathers originally developed on dinosaurs as a means of Insulation; those small dinosaurs that then grew longer feathers may have found them helpful in gliding, which would have begun the evolutionary process that resulted in some proto-birds like Archaeopteryx and Microraptor zhaoianus.
Dilong is a tyrannosauroid which predates Tyrannosaurus rex by 60 to 70 million years.
Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class Bedding, especially pillows, blankets, and mattresses.

Fossil remains have been found in China of the oldest and smallest ancestor to the T.rex, he was given the name Dilong paradoxus, meaning "surprising dragon", i'm just going to call him Dilong.
Since the Dilong that were found ranged in the 5 foot region, smaller bodies could have used these proto feathers for a sourse of warmth.

O'Connor, page 42]--such as a hand with three fingers (most tyrannosaurs' hands had just two fingers) and a relatively small body (it was just five feet long).

The jackal-sized Dilong was far smaller than T. rex, which roamed the Earth some 65 million years later.
But while the forelimbs of T. rex had dwindled until they were almost useless, Dilong would have been able to clutch food in its hands and bring it to its mouth.
Dilong's protofeathers are not what we would recognise as feathers today, but are their evolutionary precursors.

 LiveScience.com: Avian Ancestors: Dinosaurs That Learned to Fly
This early cousin of Tyrannosaurus rex lived about 130 million years ago and was covered in hairlike protofeathers, which are precursors to the feathers of modern birds.
It is named after the mythical Chinese Emperor dragon, Dilong, and from the fact that it was “paradoxically” small and feathered.
The feathers were probably used for warmth, and scientists suspect that juvenile T-rexes might also have had feathers, and that the feathers were shed as the animal matured.

Two examples of the big boy's ancestor - who has been named Dilong paradoxus, meaning "surprising dragon" - were found by teams from the Chinese Academy of Sciences in Beijing and the American Museum of Natural History in New York.
But by the time T. rex had evolved from its ancestral tyrannosaurs like Dilong, it's possible that the huge animals no longer needed true feathers as adults - and instead were covered with scales because they needed to dump excess heat from their big bodies, very much the way elephants do today, Norell said.
In Dilong's time - between 129 million and 139 million years ago - the primitive tyrannosaurs must have lived around lakes amid the earliest true flowering plants, in a verdant forest of early conifers much like today's pines and ginkgoes, Norell said.
