Riojasaurus
Click here for more Riojasaurus Pictures
Riojasaurus was a herbivore (plant-eater) that lived in South America
during the late Triassic period,
about 225 to 219 million years ago.
The name means "Rioja lizard" and was chosen because the
first specimen was found in the La Rioja Province of Argentina.
Riojasaurus was about to 33 feet (10 meters) long. It had a heavy body
and bulky legs, as well as a long neck and tail.
The structure of the animal's
skeleton suggests that it always walked on all
four legs (relatively unusual for an early dinosaur), although it
could probably rear up on its hind legs.

Riojasaurus Facts
Here is a summary of some of the key facts about Riojasaurus:
- Riojasaurus was a genus of dinosaur.
- "Riojasaurus" means "lizard from Rioja" (after a province in Argentina).
- Riojasaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Riojasaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
- Riojasaurus was a Prosauropod - a member of a group of related early herbivorous (plant-eating) dinosaurs which had long necks, small heads, shorter forelimbs than hind limbs, and a thumb claw.
- Riojasaurus lived between about 225 million years ago and 219 million years ago, during the Triassic period.
- Riojasaurus lived in South America.
- Riojasaurus was a herbivore (plant-eater).
- Riojasaurus was about 33 feet (10 meters) long.

Excerpt: Aardonyx Fossil range: Early Jurassic , 195 Ma Pre O S D C P T J K Pg N Aardonyx (Afrikaans aard , "earth" + Greek onux , "nail, claw") is a genus of prosauropod dinosaur . It is known from the type species Aardonyx celestae found from the Lower Jurassic Elliot Formation of South Africa . A. celestae was named after Celeste Yates, who prepared much of the first known fossil material of the species. It has arm features that are intermediate between prosauropods and sauropods . Based on the structure of the hind limbs and pelvic girdle of Aardonyx , the dinosaur normally moved bipedally but could drop to quadrupedal movement similar to Iguanodon . It shares some attributes with giant quadrupedal sauropods like Apatosaurus . Australian paleontologist Adam Yates and his team's discovery of the genus was published online before print in Proceedings of the Royal Society B in November 2009, and is scheduled to appear in the March 2010 issue. British paleontologist Paul Barrett of the Natural History Museum , London, who was not involved in the research, commented that the discovery of Aardonyx "helps to fill a marked gap in our knowledge of sauropod evolution, showing how a primarily two-legged animal could start to acquire the specific features necessary for a life spent on all-fours". According to Dr. Matthew Bonnan , a co-author on the study, "We already knew that the ear... |

Kapitel: Plateosaurus, Lufengosaurus, Massospondylus, Riojasaurus, Thecodontosaurus, Anchisaurus, Unaysaurus, Lessemsaurus, Mussaurus, Ammosaurus, Eucnemesaurus. Aus Wikipedia. Nicht dargestellt. Auszug: Plateosaurus (meaning 'flat lizard') is a genus of plateosaurid prosauropod dinosaur that lived during the Late Triassic period, around 216 to 199 million years ago in what is now Central and Northern Europe. The latest research recognizes two species: the type species P. engelhardti from the late Norian and Rhaetian, and the slightly earlier P. gracilis from the lower Norian, although others have been assigned in the past, and there is no broad consensus on the species taxonomy of plateosaurid dinosaurs. Similarly, there are a plethora of synonyms at the genus level. Discovered in 1834 by Johann Friedrich Engelhardt and described three years later by Hermann von Meyer, Plateosaurus was the fifth dinosaur genus to be named that today is still considered valid. However, it was not one of the three genera originally used by Richard Owen in 1842 to define Dinosauria, because at the time it was poorly known and difficult to identify as a dinosaur. Plateosaurus is now among the best known dinosaurs, with over 100 skeletons found, some of them nearly complete. Plateosaurus was a bipedal herbivore with a small skull on a long, mobile neck, sharp but plump plant-crushing teeth, powerful hind limbs, and a grasping hand with a large thumb claw possibly used for defence and feeding. Unusually for a dinosaurs, Plateosaurus showed strong developmental plasticity: fully grown individuals were between 4.8 and 10 metres (16 and 33 ft) long and weighed between 600 to 4,000 kilograms (1,300 to 8,800 lb). Commonly, the animals lived for 10 to 25 years. Despite the great quantity and excellent quality of the fossil material, Plateosaurus was for a long time one of the most misunderstood dinosaurs.
