Sinosauropteryx
_s.jpg)
Sinosauropteryx was a small carnivore (meat-eater) dinosaur that lived in
China during the early
Cretaceous period,
between about 125 and 122 million years ago.
Sinosauropteryx was about 3¼ to 4 feet (1 to 1.2 meters) long - most of its length
being taken up by its extremely long tail. It is estimated to have weighed around 5½ pounds (2.5 kilograms).
Fossils of
Sinosauropteryx show had a covering of what look like down-like feathers.
The usual interpretation is that these are indeed primitive feathers with a
very simple structure, however an alternative interpretation has also been
proposed - that they are the remains of collagen fibers. It has been noted
that patches appear on the sides of the body, back, neck skull, arms, leg,
and the top and bottom of the tail, suggesting that the animal was completely
covered with these "feathers" in life. On the tail, there are also
a series of lighter and darker bands, which may be the remains of melanin,
and thus give an indication of the animal's living appearance.
We also have some direct evidence of Sinosauropteryx's diet. One
fossil
specimen shows the remains of a lizard in its stomach. A second
fossil,
which is also believed to be Sinosauropteryx, was found to contain
the remains of the jawbones of three small mammals, two of the jaws
being from
Zhangheotherium (a Symmetrodont - an extinct order of primitive mammals),
and the other one being from
Sinobaatar (a Multituberculate - another extinct order of mammals).
Finally we also some information about the reproduction of
Sinosauropteryx. The fossil
which had a lizard as part of its preserved stomach content, also contained
a number of eggs (two of which can be clearly seen). It is not thought that these are eggs
that the animal ate (because they are in the wrong part of the body), but rather they
are thought to be the animal's own unlaid eggs. Each egg is about 1 inch (25 millimeters) wide,
and just under 1½ inches (38 millimeters) long.

Sinosauropteryx Facts
Here is a summary of some of the key facts about Sinosauropteryx:
- Sinosauropteryx was a genus of dinosaur.
- "Sinosauropteryx" means "Chinese lizard-wing".
- Sinosauropteryx was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Sinosauropteryx was not closely related to lizards, it did have similarly shaped pelvic bones.
- Sinosauropteryx was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Sinosauropteryx was not itself an ancestor of birds).
- Sinosauropteryx lived between about 125 million years ago and 122 million years ago, during the Cretaceous period.
- Sinosauropteryx lived in China.
- Sinosauropteryx was a carnivore (meat-eater).
- Sinosauropteryx was about 3¼ to 4 feet (1 to 1.2 meters) long.

Extracto: Velociraptor (lat. "ladrón veloz"), en castellano velocirráptor, es un género de dinosaurios terópodos dromeosáuridos que vivieron durante el Campaniano, hacia finales del período Cretácico, hace unos 70 a 65 millones de años. Si bien hay sólo una especie reconocida, V. mongoliensis, otras han sido nominadas en el pasado. Se han hallado fósiles de esta especie en Asia Central, en Mongolia y China. Aunque más pequeño que otros dromeosáuridos como el deinonico y el aquilobator, el velocirráptor tenía muchos rasgos anatómicos similares a ellos. Fue un carnívoro bípedo, con una cola larga y rígida, y tres garras, una alargada y curva en cada pata, la cual usaba para matar a sus presas. A diferencia de otros dromeosáuridos el velocirráptor poseía un cráneo bajo y alargado, y un hocico chato, dirigido hacia arriba. Poseía patas traseras de gran longitud, lo que expresa (al igual que el nombre) su aparente gran velocidad. Debido a su destacada aparición en la novela de Michael Crichton Parque jurásico, el Velociraptor (comúnmente apodado "raptor") es uno de los géneros de dinosaurios más conocidos por el público general. También es bien conocido por los paleontólogos, con no menos de una docena de esqueletos fósiles recobrados - la mayor cantidad descubierta de un dromaeosáurido. Un espécimen particularmente famoso es el que muestra a un Velociraptor enzarzado en una batalla con un Protoceratops. El velocirráptor comparado en tamaño con un humano.Para ser un dromeosáurido el velocirráptor era relativamente pequeño, los adultos alcanzaban una longitud de 1,8 m, y aproximadamente 0,5 metros de altura a la cadera, pesa... |

Examining and interpreting recent spectacular fossil discoveries in China, paleontologists have arrived at a prevailing view: there is now incontrovertible evidence that birds represent the last living dinosaur. But is this conclusion beyond dispute? In this book, evolutionary biologist Alan Feduccia provides the most comprehensive discussion yet of the avian and associated evidence found in China, then exposes the massive, unfounded speculation that has accompanied these discoveries and been published in the pages of prestigious scientific journals. Advocates of the current orthodoxy on bird origins have ignored contrary data, misinterpreted fossils, and used faulty reasoning, the author argues. He considers why and how the debate has become so polemical and makes a plea to refocus the discussion by “breaking away from methodological straitjackets and viewing the world of origins anew.” Drawing on a lifetime of study, he offers his own current understanding of the origin of birds and avian flight.

Feathers are an evolutionary marvel: aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told. In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us? Engineers call feathers the most efficient insulating material ever discovered, and they are at the root of biology's most enduring debate. They silence the flight of owls and keep penguins dry below the ice. They have decorated queens, jesters, and priests. And they have inked documents from the Constitution to the novels of Jane Austen. Feathers is a captivating and beautiful exploration of this most enchanting object. |

Over the past decade, fossil finds from China have stunned the world, grabbing headlines and changing perceptions with a wealth of new discoveries. Many of these finds were first announced to English speakers in the journal Nature. Rise of the Dragon gathers together sixteen of these original reports, some augmented with commentaries originally published in Nature's "News and Views" section.
Perhaps the best known of these new Chinese fossils are the famous feathered dinosaurs from Liaoning Province, which may help end one of the most intense debates in paleontology—whether birds evolved from dinosaurs. But other finds have been just as spectacular, such as the minutely preserved (to the cellular level) animal embryos of the 670 million-year-old Duoshantuo phosphorites, or the world's oldest known fish, from the Chengjiang formation in southwestern Yunnan Province.
Rise of the Dragon makes descriptions and detailed discussions of these important finds available in one convenient volume for paleontologists and serious fossil fans.

This lavishly illustrated volume is the first authoritative dinosaur book in the style of a field guide. World-renowned dinosaur illustrator and researcher Gregory Paul provides comprehensive visual and textual coverage of the great Mesozoic animals that gave rise to the living dinosaurs, the birds. Incorporating the new discoveries and research that are radically transforming what we know about dinosaurs, this book is distinguished both by its scientific accuracy and the quality and quantity of its illustrations. It presents thorough descriptions of more than 735 dinosaur species and features more than 600 color and black-and-white images, including unique skeletal drawings, "life" studies, and scenic views--illustrations that depict the full range of dinosaurs, from small, feathered creatures to whale-sized supersauropods. Heavily illustrated species accounts of the major dinosaur groups are preceded by an extensive introduction that covers dinosaur history and biology, the extinction of nonavian dinosaurs, the origin of birds, and the history of dinosaur paleontology--and that also gives a taste of what it might be like to travel back to the time of the dinosaurs. The Princeton Field Guide to Dinosaurs is a must-have for anyone who loves dinosaurs, from the amateur enthusiast to the professional paleontologist. - The first authoritative field guide to dinosaurs
- Covers more than 735 species
- Beautiful, large-format volume
