Allosaurus was among the earliest dinosaur discoveries, and fossils are plentiful, making it a darling of paleontologists as well as amateur dinosaur observers.
This large theropod lived 155 million to 150 million years ago during the late Jurassic Period. More than 10,000 bones from about 46 specimens have been unearthed in the Cleveland-Lloyd Quarry in Utah, making the Allosaurus the most commonly discovered fossil in Utah. It is also Utah's state fossil. Allosaurus fossils have also been discovered in Thailand as well as in Portugal and other parts of Europe. Possible Allosaurus fossils have been discovered in Africa and Australia.

Seven species of Allosaurus have been identified, Allosaurus fragilis being the best-known. There is some debate about whether there are more species or whether the specimens in question belong to other genera.

The name Allosaurus is derived from the Greek allos ("different" or "other") and sauros ("lizard"). One feature that makes this dinosaur "different" is its unusual vertebrae. It had nine vertebrae in its neck, 14 in the back and five supporting its hips. There were hollow spaces in the neck and anterior back vertebrae. Such spaces, which are

    By looking at the title do you know what it is about? The Tyrant Lizard king is actually the nickname of a dinosaur you probably do know which is, Tyrannosaurus Rex. The T. Rex was about Forty feet long, about fifth teen to twenty feet tall. Although the Tyrannosaurus Rex was big it was not the biggest dinosaur, compared to other dinosaurs he was quite small! Unlike what you may think, the T. Rex might not have been green; no one knows what color it was. The Tyrannosaurus Rex had a big head. The Tyrannosaurus Rex had two strong legs and two tiny little arms (Three feet long) each with two fingers. He also had a straight stiff tail that was good for giving it balance and for it to make quick turns. The T. Rex weighed…

    This unique species within the horned dinosaur group is given its name by it’s discoverer Wendy Sloboda. Related to Triceratops, it has a body similar to the extant rhinoceros. Wendiceratops pinhornensis was a quadruped. supported by its leaf-shaped teeth and cropping beak it is believed to be a herbivore. It was approximately 6 meters long and weighed over a ton. Wendiceratops dates back 79 million years ago, during the Late Cretaceous period. One of its distinctive features is its skull ornamentation. It has a decorated neck frill with forward protruding hook-like horns along the margin of its frill. This is unusual to early members of the horned dinosaur family. The significance of Wendiceratops lies in its nasal horn. Wendiceratops is the…

    Paleontologist Rainer Schoch of the State Museum of Natural History Stuttgart (http://www.naturkundemuseum-bw.de/) in Germany believes that Pappochelys is the missing link between lizards and turtles. The reptile's age and the fact that it is the oldest fossil is one piece of evidence, but the greater reason is because the reptile's anatomy is a more primitive version of our modern day turtles.…

    Othniel Charles Marsh then pointed out that Cope had but the skull of the dinosaur or the wrong end of its body, humiliated and embarrassed Cope. The rivalry between the two pushed each other to work harder on their research. There were many times where the two men were competing to describe the most new dinosaurs fossils. Sadly, this led to much rushing of the scientist and meant that there were times when the men would mix up different bones and even use a dinosaurs name one than once. The rivalry between the two men was still extremely positive on the study of paleontology. Before Cope and Marsh had started to research the fossils there were only eighteen dinosaurs known. Between Edward Drinker Cope and Othniel Charles Marsh they had named more than 130 new…

    Ophiacodon Description

    • 454 Words
    • 2 Pages

    Echo-Description of toy-- Our toy design is an Ophiacodon( pronunciation Oh-fee-ack-oh-don.) An Ophiacodon is a lizard like dinosaur. The longest this particular species grows is 3 meters long. How Ophiacodon lived and hunted is still a matter of debate today with some claiming that it was a semi aquatic carnivore that fed on fish and amphibians. Support for this comes from the small and numerous teeth that would have been great for gripping slippery prey like fish. There is also a notch at the end of the upper jaw, a trait commonly seen in animals that have a piscivorous diet. Others however suggest that the deep skull would have been more of a hindrance and that the legs seem to support and lift the body up as opposed to just sprawling out…

    For me, the obvious pick was the Triceratops. Like the Tyrannasaurus Rex, the Triceratops was quite popular in the Jurassic Park films. It was mostly known for its three huge horns and long stretched out neck frill (protecting its neck). Unfortunately, the movies and cartoons depicted the Triceratops poorly because it in fact wasn’t capable of charging at larger predators and withstanding the punishment with its skull. Triceratops skulls have been found with Tyrannosaurus Rex toothmarks clearly, while no injuries created by the Triceratops have ever been found on a T Rex. Additionally while there is fossil confirmation that shows tyrannosaur tooth stamps on Triceratops fossils,‭ ‬no tyrannosaurs have been demonstrated to have been harmed by…

    The false fossil left China in June 1998 and eventually turned up in a rocks and fossil shop in Tucson, AZ, where it was discovered and eventually purchased by Stephen Czerkas. Czerkas was an amaeteur fossil collector who probably didn’t know any better than to purchase pretend petrified remains. He was extremely excited and proceeded to contact an expert and call for a study of the fossil. A team from National Geographic agreed to keep details about this study secret until the science journal article came out. The press was playing this up, calling this dinosaur “the lost link between dinosaurs and modern day birds”. It was supposed to be huge; people have been looking for something like this for ages. The team affectionately began referring to the fossil as Archaeoraptor. The world of paleontology was going mad with excitement. Unfortunately, these dreams of new discovery would not last…

    During the Jurassic period, relatives of the small, quadrupedal, plant-eating prosauropods of the Triassic period gradually evolved into gigantic sauropods like Brachiosaurus and Diplodocus. This period also saw the rise of medium- to large-sized theropod dinosaurs like Allosaurus and Megalosaurus, which helps explain the evolution of the earliest ankylosaurs (armored herbivorous dinosaurs). The…

    Chapter 1: Dinosaurs (Introduction) Dinosaurs are a diverse group of animals belonging to the family of Dinosauria. The term “dinosaur” originated from the Greek words “deinos” which means fearfully great and “sauros” which means a lizard. The term “dinosaur”, was coined in 1982 by Richard Owen and was meant to refer to dinosaurs’ impressive size rather their scary appearance. Dinosaurs are considered to be the biggest animals to ever walk on Earth.…

    Diplodocus was more lightly built than the other giant sauropods, and may have weighed only about 10-20 tons. Its backbone had extra bones underneath it, which had bony protrusions running both forwards and backwards (anvil shaped), a "double beam", probably for support and extra mobility of its neck and tail. It may have used its whip-like tail for protection. It has been determined that Diplodocus could not hold their necks over about 17 feet (5.4 m) off the ground (Parrish and Stevens,1999).…
