Allosaurus
Click here for more Allosaurus Pictures
Allosaurus was a common carnivorous (meat-eating) dinosaur
in North America during the late Jurassic and early
Cretaceous period,
approximately 154 to 135 million
years ago. Allosaurus
fossils
have also been found in Africa and
Australia.
Allosaurus was up to 39 feet (11.9 meters) long,
and weighed approximately 1.7 tons.
Some scientists believe Allosaurus was too heavy to chase down prey, and
therefore was probably a scavenger. However, others believe that Allosaurus
may have been quite agile, and could even have hunted in packs to bring down
giant herbivores (plant-eaters) such as
Apatosaurus or
Diplodocus.
The first Allosaurus
fossil
was incorrectly described as a "petrified horse hoof".
In fact, it was a caudal vertebra (tail bone) of this dinosaur, although
it was not recognized as such at the time.
Using much more material, including a partial skeleton,
Othniel C. Marsh
published the first description of Allosaurus in 1877.
One of the most important Allosaurus specimens found, was
discovered in
Wyoming,
in 1991.
This animal, which has been nicknamed "Big Al", was actually smaller than
average for its particular species of Allosaurus (it was probably not fully grown),
and even though many bones showed signs of infection (which may have contributed to the animal's death),
was very important because the skeleton was 95% complete. Furthermore, the same team which discovered
"Big Al", also subsequently discovered a second well-preserved specimen, which has been nicknamed
"Big Al Two".
The discovery, and possible life-story of "Big Al", served as inspiration
for a special episode of the BBC/Discovery TV series, Walking With Dinosaurs,
entitled "The Ballad of Big Al".
Allosaurus has been designated the official state
fossil of
Utah,
since
1988.

Allosaurus Facts
Here is a summary of some of the key facts about Allosaurus:
- Allosaurus was a genus of dinosaur.
- "Allosaurus" means "different lizard" or "strange lizard". This name was chosen by Othniel C. Marsh in 1877.
- Allosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Allosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.
- Allosaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Allosaurus was not itself an ancestor of birds).
- Allosaurus lived between about 154 million years ago and 135 million years ago, during the late Jurassic and early Cretaceous periods.
- Allosaurus lived in North America, Africa and Australia.
- Allosaurus was a carnivore (meat-eater).
- Some scientists think that Allosaurus was probably a scavenger, but others think it was an active predator. There is even possibility that Allosaurus may have been a pack hunting animal, with individuals working together to bring down prey.
- Allosaurus was about 39 feet (11.9 meters) long.
- Allosaurus weighed about 1.7 tons.
- Allosaurus is the official state fossil of Utah.

With horns above its eyes and claws on its hands, Allosaurus would make a better ally than enemy.Another meat-eating dinosaur, Allosaurus had a unique skeleton. Instead of having ribs that were attached to other bones in its body, this dinosaur had ribs that were attached to its skin. Its vertebrae were different too; the bones in its back were bulky and heavy. Standing at a height of over sixteen feet and weighing over one ton, this predator was the biggest carnivore around. Even though it had short arms, its hands had sharp claws for catching plant-eating dinosaurs. Often, Allosaurus would hunt together in groups, making it easier to take down their prey. Living into its twenties, Allosaurus was an intelligent and fierce predator. Fun Facts: As a teenager, Allosaurus could gain as much as one tenth its adult body weight. Zoological Name:Allosaurus

In this second installment of the series, world-famous paleontologist Professor Reginald Barrister and third-grade dinosaur experts Nate and Emily travel back to dinosaur times to investigate a mysterious Allosaurus fossil. The fossil shows the dominant predator of Jurassic North America with large armor plates across its back, but Allosaurus didn't have armor--or did it? Professor Barrister, Nate and Emily will have to brave gigantic sauropods, spike wielding herbivores, and of course the monstrous Allosaurus to solve the mystery! Stephen Penner is a children's book author and illustrator who lives near Seattle with his wife, young son and even younger daughter. He got the idea for "Professor Barrister's Dinosaur Mysteries" from a game he made up with his dinosaur-loving son. When not writing and drawing, he enjoys painting, reading and traveling. |

Click Here | Product Description:
In Abbeville's new "Dinosaurs" series, a talented artist and a noted paleontologist have teamed up to re-create the vanished world of the dinosaurs in comic-book form. Each volume in the series tells the action-packed yet scientifically accurate story of a different dinosaur living in its particular geological time and place. At the back of each volume, meanwhile, are several short essays, abundantly illustrated with original drawings and photographs of fossils, that explain more about the creatures and geographical settings encountered in the comic. These essays, written in terms that kids will understand, reveal not only what paleontologists have learned about the age of the dinosaurs, but also how they have learned it, by examining fossils and other types of evidence. "The Hunting Pack", the third title in the series, depicts life in a herd of Allosaurus in the late Jurassic period, 150 million years ago. As these powerful predators hunt herbivores like Camarasaurus and Stegosaurus and look after their offspring, an aggressive young Allosaurus challenges the battle-scarred dominant male for leadership of the pack. The essays at the back of the book explore the comic's remarkable setting, the ancient ecosystem of the Morrison Formation, located in what is today the western United States and Canada. |
