Velociraptor

('swift thief', 'swift plunderer' or 'swift bird of prey')

The velociraptor was a small dinosaur!! It ate meat. The fossils were found in Central Asia. They hunted in packs. It was 2 feet tall, 6 feet in length and 30 pounds in weight. It had more killing power than almost any other dinosaur of its weight. They were very intelligent.
Velociraptor had approximately 80 conical, curved teeth, with long, flattened snout. Its teeth measured about 2.5 centimeter long. Its head was approximately 18 centimeters long. Its neck was S-shaped. This dinosaur had long, slender legs with four-toed clawed feet. Its arms had three clawed fingers.
Velociraptor was known to have existed during the late cretaceous period, approximately 80 to 85 million years ago. It was believed to have inhabited warm, arid environments, almost desert-like with rivers or streams.
The Velociraptor was between 5 to 6 feet long, and about 2.5 to 3 feet tall. It
weighed around 15 to 40 pounds (weights of dinosaurs are very hard to estimate).
Physical Description:
The Velociraptor had an s-shaped neck, two arms that
had claws with three fingers on each hand, and long thin legs with claws that
had four toes on each foot. It's mouth had sharp, curved teeth and it had a
really flat long mouth and nose,and a long stiff tail.

Diplodocus

('double beamed')
It has a long neck and a long tail and it has five toes on each foot. It has a long neck. Diplodocus are quadrupeds meaning they stand on all four legs. The dinosaur walked on four legs.
Diplodocus was one of the largest dinosaurs ever discovered.
It was the longest land animal, but not the heaviest. It was a sauropod, a
"lizard-hipped" dinosaur. Diplodocus carnegii was named after industrialist and
philanthropist Andrew Carnegie. This sauropod was the most famous dinosaur on
the planet in the last century. There is a famous life-size replica of the
Diplodocus nicknamed "Dippy" in front of the Carnegie Museum of National History
(Pittsburgh, PA, USA). Diplodocus was a herbivore, it ate only plants; main food
was probably conifers. It must have eaten an enormous amount of plants each day.
It didn't chew them, it swallowed leaves whole. It swallowed also stones
(gastroliths), which it held in its stomach. They helped by digesting
tough
plant material. Diplodocus may have traveled in herds, migrating when
the food supply was depleted. It probably bred from eggs, like other
sauropods.
It is thought, that the eggs were laid as the dinosaur was
walking.
This sauropod was a huge creature with an extremely long neck and a
long, whip-like tail. Most of this herbivorous animals length was in the neck
and tail. Diplodocus had an elongated snout with nostrils on top of the head and
simple peg like teeth for stripping soft foliage. It had one of the smallest
brains (the size of fist), its intelligence was among the lowest of the
dinosaurs.
The name Diplodocus means "double beam" and describes a special
feature of the backbone. It had slender limbs and hind legs, longer than the
front legs; it gave him access to both low and high growing plants. It was a
quadrupedal, it moved slowly on four column-like legs. All legs had five-toed
(like elephant); one toe on each foot had a thumb claw, probably for
protection.

Hadrosaurus

('sturdy lizard')
These dinosaurs lived in Asia and North America 80 million years ago. Being herbivores they ate only plants. It always went back to the same place each year to lay its eggs. It had bumpy skin and hoofed feet and horny toothless beak. Hadrosaurus was the first dinosaur discovered with almost it's entire skeleton intact.
In 1838, William Estaugh Hopkins was digging in a marl pit when he exposed large bones. He had the bones on show at his home, Birdwood in Haddonfield, New Jersey. In 1858 these bones sparked the attention of a visitor, William Parker Foulke. The skeleton was dug out from the marl pit in 1858 by Foulke. In the same year, the species was named by paleontologist Joseph Leidy in the same year, from an approximately complete set of limbs, along with a pelvis, several parts of the feet, twenty-eight vertebrae (including eighteen from the tail), eight teeth and two small parts of the jaw. Leidy recognized that these bones were from a dinosaur by their resemblance to those of the **Iguanadon**, exposed in England some decades before, but the skeleton of Hadrosaurus was far more entire and was at the time the most complete dinosaur skeleton known. Leidy's monograph Cretaceous Reptiles of the United States, telling Hadrosaurus more completely and with illustrations, was written in 1860 but the American Civil War postponed its publication until 1865. Leidy reconstructed Hadrosaurus as a biped, in contrast to the view at the time that such dinosaurs were quadrupedal. The entire skeleton was entirely assembled in 1868 by a team including English sculptor and naturalist Benjamin Waterhouse Hawkins and was put on show at Philadelphia Academy of Natural Sciences, where it remains available for public viewing.Despite the fact that the family Hadrosauridae is named after this genus, there is no skull known. The skeleton is indistinguishable from that of other hadrosaurins.

('different lizard')
Allosaurus is a meat eater. We know that because it has sharp teeth. We also now it because of small arms. Allosaurus could run really fast. they lived near us. One of its nails was 30 centimeters long. I would be scared of an allosaurus. An average Allosaurusweighed about 4 tons (3.6 metric tons) and measured 35 feet when did it live how did it fined its food what did it look like what is special aboput this dinosaur what colers wher they how meny
The Allosaurus has a name that literally means the other lizard. Possibly this was due to the fact that the first bones were discovered during the bone wars between Edward Cope and Othniel Marsh during the late 19th century in Wyoming and Colorado. What started as competition for prestige degenerated into a bitter feud where employees of both scientists staged attacks on each other. Dinosaur bones were destroyed though underhanded means, with theft and bribery rife. When success was measured in the weight of bones found, is it any wonder that that the Allosaurus simply became the other lizard?.
The Allosaurus a member of the Allosaurid family was first discovered during the closing years of the 19th century by Othniel Charles Marsh in 1877. It existed in the late Jurassic period about 150 million years ago and almost all of it’s fossils have been in the Morrison Formation in the NorthAmerica, as well as in Portugal and Tanzania. The name Allosaurus means “different lizard” and is derived from the Greek root word “allos” meaning “different”.
The skull of the Allosaurus was estimated to be around 33 inches in length giving it a decent sized jaw size. Each premaxilla (the bones forming the tip of the snout) held five teeth and each maxilla (the bones in the upper jaw) and dentary (the bones of the lower jaw) had around 14 to 17 teeth giving the Allosaurus plenty of teeth for the size of it’s skull.

Ankylosaurus

('fused lizard')

An ankylosaurus has armored plates on its body to protect it. It's cochl can fight the meat eaters. It had two rows of spikes. It was a Herbivore. Ankylosaurus had four short legs.
The defining point of an ankylosaurus is its armor. Their armor consists of very tough bones and scales embedded in its skin. They were a very large animal. Ankylosauruses could be up to 30 feet long, 6 feet wide, and about 4 feet high. Most animals today are not wider than they are tall, so one can understand how awkward this animal looked (think of a stingray mixed with a rhino… on land). The ankylosaurus had 4 feet and its rear legs were taller than its front legs. The ankylosaurus had a very large bony tail “club”. The dinosaur also had 2 long rows of spikes coming from the side of its body and horns protruding backwards from the back of its head.

('near lizard')
A pleisiosaur can swim in the water. A pleisiosaur walks on four legs and it has a long tail and a long neck it even has a small head. It had sharp teeth, a pointed tail and some fins. The fossils were found all over the world. It ate fish and other ocean creatures. It was 8 - 46 feet long.
The plesiosaurus was one of the largest aquatic animals and lived throughout the cretaceous period).It grew up to twenty three meters long, making it among some of the largest sea creatures.Like other sauropterygians it was a very successful reptile that thrived during the age of the dinosaurs. The plesiosaur was easily identifiable by its four large flippers.The neck of this animal was very long similar to an apatosaurus/ brontosaurus.However, many illustrations of this animal show a swan like neck, but its neck was actually too long for this to be accurate.The blood would not be able to flow from its heart to its head.



external image 262599971_c406328a9c_t.jpg Triceratops

('three-horned face')
Triceratops is a plant eater. He has three horns and can push stuff over. It was born by eggs.
Fossils show that Triceratops was about 30 feet (9 meters) long and 10 feet (3 meters) tall and weighed 4 to 6 tons. Stout limbs supported Triceratops's weight, but it was unlikely the dinosaur could move very quickly.
Triceratops's head was its most imposing feature. It measured 4 to 5 feet (1.2 to 1.5 meters) across and was ornamented with impressive horns and a head plate. It used its horns—a short one above its mouth and two long ones above its eyes—to charge predators, such as T. rex.
Behind its horns was a 6-foot-wide (1.8-meter-wide) head frill made of bone. Scientists aren't sure what purpose the frill served. It may have protected the dinosaur's neck from predators, or it may have attracted mates in mating rituals. It may have acted as a radiator, helping Triceratops regulate its body temperature.
This ceratopsian, or horned dinosaur, was one of the last dinosaurs in the late Cretaceous period. It lived just before the Cretaceous-Tertiary extinction 65 million years ago.
Triceratops ("three-horned face") was a ceratopsid herbivorous dinosaurspecies from the Latest Cretaceous time of North America. It was about 9 m (30 ft) long, and almost certainly weighed approximately 5,400 kg (12,000 lb)
Triceratops was exposed by John Bell Hatcher in 1888. Its statement as a legitimate dinosaur came when a whole skull was found. It was named by Othniel Charles Marsh in 1889. Two years earlier, however, he misidentified the Triceratops as a type of bison. The strong natural world of the animal's skull has ensured that many examples have been preserved as fossils, allowing variations between species and persons to be studied.
Known species of Triceratops include T. prorsus and T. horridus. Diceratops was formerly supposed to be a species of Triceratops as well, but is currently documented as a separate genus and species.

('tyrant lizard king
Did you know that they found a skeleton of a Tyrannosaurus in Saskatchewan? In 1994 they found the remains near Eastend, SK. Do you know his nickname? Ask Mr. M for the answer! His nickname is Scotty. And he can be seen at the T.Rex Discovery Center in Eastend.SK.Its brain is smaller then a head of broccoli. A Tyrannosaurus is 40 feet long. A T-Rex has 50 to 60 bone crunching teeth.

T-Rex has a good sense of smell.

T-Rex was one of the best known dinosaurs, but it didn't live all that long. T-Rex came along just before the dinosaurs became extinct.

Tyrannosaurus rex ("tyrant lizard king"), also recognized colloquially as The King of the Dinosaurs, was a huge carnivorous theropod dinosaur from the Upper Maastrichtian, the last stage of the Cretaceous time, 65–66 million years ago. Its fossilleftovers are rare — as of 2005 only 30 specimens had been found1, including three total skulls. The first specimens found played a significant role in the Bone Wars. T. rex is the best known carnivorous dinosaur, chiefly because it was consideration to be the largest to have ever existed for a long time. While there have been sensationalistic claims of new, larger theropods "dethroning" T. rex as the King of the Dinosaurs, proof remains scant and open to debate. T. rex will very likely remain a subject of ongoing scientific investigate and popular culture.
The first specimen (a partial vertebra) was establish by Edward Cope in 1892 and was described as Manospondylus gigas. It was assigned to Tyrannosaurus rex in 1912 by Henry Osborn. Barnum Brown, helper curator of the American Museum of Natural History, establishes the second T. Rex Skeleton in Wyoming in 1900. This specimen was at first named Dynamosaurus imperiosus in the same paper in which Tyrannosaurus rex was described. Were it not for page order, Dynamosaurus would have turn out to be the official name. The original "Dynamosaurus" material resides in the collections of the Natural History Museum, London.
Up to 13 meters (43 feet) in length and 4–7 tons in weight, T. rex was one of the main carnivorous dinosaurs of all time. Compared to additional carnivorous dinosaurs, the skull of Tyrannosaurus is a lot modified. Many of the bones are compound together, preventing group between them. The bones themselves are much more massive than is typical of a theropod, and the jagged teeth, far from being bladelike, are massive and oval in cross-section. Heavy wear and the bite script found on bones of other dinosaurs indicate that these teeth could bite into solid bone. The teeth are often damaged or broken at the tips from heavy use but, unlike mammals, were continually full-grown and shed all through the life of the animal. Compared to other giant carnivorous dinosaurs such as Allosaurus, Tyrannosaurus appears to have had a sizeable brain, but it was almost certainly not chiefly intelligent by mammalian standards.
The neck was short and very a lot muscled. The arms of T. rex were small, maybe to make up for the weight of its huge head, but were very sturdy. Paleontologists continue to argue about what reason, if any, they served. They may have served to grab the female during sex, and surely helped the animal to get up, temporarily behind the front body like the struts of a detached truck trailer. The legs were comparatively long and slender for an animal of this size. Recent investigate suggests that an adult Tyrannosaurus could not run much, but juveniles might have been with no trouble as fast as a modern lion. Most scientists and paleontologists adults were not fast runners. The configuration of its hip bone relative to the legs and spine propose a muscle tissue expansion and posture that would have enabled the animal to run close to 30 mph (50 km/h) in adulthood. Evidence of its prey in fossils and migrating patterns propose this animal probably had to have been able to sustain a speed strong enough to hunt its prey. To recompense for its immense bulk, the center of many bones were hollowed out. This significantly reduced the weight of the skeleton while maintaining much of the power of the bones.

In studying about Wikis, we came across your website. We just wanted to say that the pictures and information on dinosaurs are AWESOME! Thanks for sharing what you've learned with us. (Randy and Denise, St. Louis, MO)


Hi! We're a class in integrating tech in the classroom in a Quebec university.
We're studying to be teachers.
We love your work -- your pictures and your writing!!


Hi, I am about to get my teaching certificate here in South Florida and we are taking this technology class. One of the assignments is to create a wiki and I was looking around and found yours to be extremely interesting. I love the pictures and information about the dinosaurs. Great wiki!!! Happy wikiing!!!

I stumbled across your wiki while working with student teachers at Canterbury Christ Church University in the U.K. We are looking at ways that web technology can be used to enhance learning across the curriculum and your dinosaur wiki is a great example of the benefits of collaboration projects with wikis! Well done and thanks!
