Psittacosaurus
Psittacosaurus was a herbivore (plant-eater)
that lived in
China, Mongolia and Siberia, during the early Cretaceous period,
about 120 to 100 million years ago.
The name Psittacosaurus was coined by
Henry Fairfield Osborn
and means "parrot lizard".
Psittacosaurus was about 8 feet (2.4 meters) long. It was bipedal (walked on
two legs) and equipped with a powerful beak on its upper jaw.
Psittacosaurus jaws were filled with self-sharpening teeth that would have
been used for cropping and slicing plant material, but were unsuitable for
chewing its food. The animal is known to have swallowed stones
("gastroliths") which would have helped wear down its food as
it passed through its digestive system (probably in a similar manner to
the gizzard in modern birds) - as many as 50 gastroliths have been found
in the abdominal cavities of some specimens.
Fossils
of at least 10 different species of Psittacosaurus have been
found so far in
China,
Mongolia and
Russia,
plus a possible additional species from
Thailand. In fact,
in total
fossils
of over 400 individual animals have been collected so far, including many
complete skeletons, and of every age from hatchling to adult, making it
one of the most studied and best-known dinosaur genera.
One
fossil
specimen found in China was found to have what
appear to have been hollow tubular bristles, each about 6 inches
(16 centimeters) in a single row down its back and tail. The purpose
of these structures are not certain, but one possibility is that they
were used for display and communication. It is also not clear whether
these (or similar) structures were found on all species of
Psittacosaurus, or just on this one particular species.

Psittacosaurus Facts
Here is a summary of some of the key facts about Psittacosaurus:
- Psittacosaurus was a genus of dinosaur.
- "Psittacosaurus" means "parrot lizard".
- Psittacosaurus was a member of the Ornithischia ("bird-hipped") order of dinosaurs. What this means, is that although Psittacosaurus was not closely related to birds, it did have similarly shaped pelvic bones.
- Psittacosaurus was a Ceratopsian - a member of a group of related herbivorous (plant-eating) dinosaurs with beaks, many of which had neck frills and horns as well.
- Psittacosaurus lived between about 120 million years ago and 100 million years ago, during the Cretaceous period.
- Psittacosaurus lived in China, Mongolia and Siberia.
- Psittacosaurus was a herbivore (plant-eater).
- Psittacosaurus is thought to have swallowed stones which would have been used to help grind up tough plant material (some modern birds do the same thing). Fossils of these stones ("gastroliths") have been found in the same rocks as Psittacosaurus.
- Psittacosaurus was up to 8 feet (2.4 meters) long.

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

Click Here | Product Description:
The literature on Chinese fossil vertebrates is extremely difficult for Western scholars to assimilate and interpret. In part, this is because much of that literature is in Chinese, and few useful reviews exist in Western languages. Yet China has an extensive vertebrate fossil record, one that plays a key role in understanding the evolution of vertebrates. Spencer Lucas gives an up-to-date review and synthesis of the Chinese vertebrate fossil record that will greatly facilitate an understanding of and further research into this outstanding fossil record. The book provides the reader with a comprehensive, chronologically ordered review of China's vertebrate fossil record. It also presents a history of vertebrate paleontological studies in China and an entrée to some important issues of systematics, evolutionary history, paleoecology, taphonomy, and functional anatomy best elucidated by China's fossils. This volume should therefore become an indispensable part of the library of any student of vertebrate evolution. (Fossil News ) |
