  Sinosauropteryx - Wikipedia, the free encyclopedia
Sinosauropteryx prima ("first Chinese lizard-feather") was the first non-avian dinosaur found with the fossilized impressions of feathers.
It lived in China during the Cretaceous period and is related to Compsognathus.
Sinosauropteryx is important because it had feather-like structures, yet was not very closely related to true birds.

 SINOSAUROPTERYX - Enchanted Learning Software
Sinosauropteryx is the first dinosaur fossil ever found that showed evidence of having feathers (albeit primitive).
Sinosauropteryx was a meat-eater and is the only dinosaur that has been found with a mammal in its stomach.
The existence of Sinosauropteryx lends credence to the theory that the birds are descended from theropod dinosaurs and not from four-legged arboreal (tree living) reptiles.

Sinosauropteryx was no exception: the large, sharply pointed, prehensile teeth that lined its jaws had serrated edges well suited to rending prey too large to be swallowed whole.
Note that in Sinosauropteryx the lower jaws are not fused together at the chin as they are in modern birds; instead elastic ligaments enabled the jaws to spread apart at their tips, also contributing to a wider gape.
Sinosauropteryx is the first non-flying dinosaur to have been found so far that shows traces of downy plumage, indicating that feathers arose before flight.

Sinosauropteryx unequivocally proves that the phylogeny of the class Aves progressed from a small theropod as proposed by Ostrom (1976) and supported by numerous workers in the field, although previously there had been no empirical evidence such as a transitional form.
Sinosauropteryx is an indication that the western Liaoning region of China is the site of origin of the class Aves and a center for bird evolution.
Sinosauropteryx, Archaeopteryx, and Confuciusornis lie in the early evolutionary transitional phase of avian evolution, whereas true birds including Sinornis santensis and Cathayornis yandica possess numerous extremely derived characters, and represent a new phase of avian evolution.

While proponents of the “thecodont” hypothesis have largely dismissed the evidence on the dogmatic a priori assertion that birds are not dinosaurs, it is nonetheless pertinent to review the data concerning the integument of allegedly feathered dinosaurs, and examine the alternative arguments put forth by some researchers (e.g., Geist et al 1997).
There is a general consensus that in Sinosauropteryx at least, we have evidence of a pelage of basal feather homologues (Ji and Ji 1996, Chen et al 1998, Padian et al in Tanke and Carpenter 2001, Paul 2002).
The integumentary structures of Sinosauropteryx prima are distributed along the midline of the body, extending from the crown of the skull caudally to the tail, and at scattered locations throughout the rest of the body including the abdomen, the knee, and adjacent to the humerus and ulna (Chen et al 1998).

Sinosauropteryx was a turkey-size dinosaur dated to the late Jurassic or early Cretaceous (Padian and Chiappe 45).
Since Sinosauropteryx prima is one of the main fossils touted by evolutionary theorists to have protofeathers, it seemed pertinent to address this specific case of alleged protofeathers.
Sinosauropteryx was just a theropod and did not possess any birdlike characteristics.

 Fossil birds, Archaeopteryx information
We regard it as the new specimen of the Sinosauropteryx prima, because its skull, teeth, girdle, hind limbs, and candal vertebras are better preserved.
It is no doubt that the bone structure of the Sinosauropteryx is obviously similar to Theropoda, such as large skull, sharp teeth, saw-tooth at rear edge of back teeth., strong skeleton, strong girdle and hind limbs, numerous scandal vertebras, and so on.
To discuss the Sinosauropteryx belongs to dinosaur or bird, it is necessary to see the biological standard distinguishing reptile and bird.

 Sinosauropteryx
Sinosauropteryx was not 'furry', then, but might have had a quill-like covering somewhat like the modified feathers in the modern flightless kiwi of New Zealand.
There's the rub: Sinosauropteryx was a small bipedal carnivorous dinosaur, but of a somewhat generalized lineage, less closely related to birds than dinosaurs which (we have good reason to believe) did not have these curious not-furry not-feathery pelts.
The researchers speculate that the structures seen in Sinosauropteryx may have been an early precursor of feathers, but used for other functions, such as thermal insulation, or possibly sexual display.

Sinosauropteryx is important not only because of its integument, but also because it is a basal coelurosaur and represents an important stage in theropod evolution that is poorly understood.

The fossil Sinosauropteryx seems to be covered with short, hairlike impressions that must be of down or rudimentary feathers, similar to those of the birds from the same sediments.
The feathers are relatively short, preserved mostly along the neck and back on the midline of the vertebral column, starting at the atlas and finishing at about half way along the tail, with very short ones, looking to be intermediate between scales and feathers near the vent, along the underside of the tail base.

 Indices Academiatrum, a Dialogue on an AIG Webcast with Jonathan Sarfati - TheologyWeb Campus
The soft anatomy of the type Sinosauropteryx displays an overall poor state of preservation, and thus data derived from this material is largely ambiguous until such time as soft-tissues are found preserved with greater fidelity in similar theropods (Martill et al 2000, Paul 2002).
Ruben et al (1997) attempted to mitigate these ambiguities with the soft-anatomy of Sinosauropteryx by arguing that preserved muscle fibers in the type Scipionyx were oriented in a position to be expected of diaphragmatic musculature.
The position of the intestines in Scipionyx and the carbonized matter in Sinosauropteryx are identical, and given these data, the most logical conclusion is that the latter represents the fossilized post-mortem decay of the intestinal tract (Paul 2002).

Nestled inside was Sinosauropteryx: 22 inches long (most of that tail), fixed forever in an awkward stance, its strong-looking legs seemingly in mid-stride, its tail straight up, its head wrenched back.
And Ji promised that "we have a good beginning to a long-term research project." He still thinks the mystery structure on Sinosauropteryx is a primitive feather.

Ruben and his team analyzed the abdominal regions of Sinosauropteryx fossils, compared the pelvis bones to various dinosaur, bird, and crocodile species, and compared Sinosauropteryx to cross-sections of crocodiles and birds.
They conclude that Sinosauropteryx's torso was clearly divided into a lung portion and an abdominal portion, with a dome-shaped, crocodile-style diaphragm that was probably pulled on by muscles that attached to their crocodile-like pelvis bones.
They conclude that the discovery of crocodile-like ventilation in a theropod poses "fundamental problems" for the theory that dinosaurs are the direct ancestors of birds.

 Insight on the News: Paleontologists rewrite script, but dinos refuse to cooperate - includes related article on ...
The most important find of all, however, is a specimen named Sinosauropteryx prima, a small, delicately boned, possibly feathered therapod dinosaur.
The specimen was discovered by an amateur fossil hunter (as the story goes) who had sold the two halves of the relief to different institutions: one to Nanjing and the other to the National Geology Museum in Beijing.
The Beijing scientists were so impressed by the appearance of feathers on the animal that they christened it Sinosauropteryx, meaning "Chinese dinosaur-bird." The Nanjing scientists, however, doubted whether the creature had feathers and considered it a new species of Compsognathus, the model for the nasty scavengers roaming the set of The Lost World.

 CM Magazine: A Moment in Time With Sinosauropteryx. A Moment in Time With Centrosaurus.
A Moment in Time with Sinosauropteryx and A Moment in Time with Centrosaurus attempt to recreate the day-to-day lives of two dinosaurs: Layah, a keenly observant young sinosauropteryx, is a chicken-sized dinosaur with feathers living some 140 million years in the past in the region that is now Liaoning, northeastern China.
By contrast, there is no modern animal analogous to the feathered, lizard-like Layah, and so the reader has more difficulty believing that she is a "real" animal.
Appropriately enough for books that trace life cycles, headings in the texts (numbered in Sinosauropteryx, but not in Centrosaurus) begin segments of rising and falling action that demarcate stages, or the passage of time, in the animals' progression towards adulthood.
