C HAPTER 1

Allosaurus By: Titan Comstock

The name Allosaurus means “different lizard” but many think he was a killing machine. Allosaurus was a meat-eater who had 70 sharp 8” long teeth. He could chew through bones easily. He even ambushed very large dinosaurs. Allosaurus had bony knobs on his head. His tail was long. Allosaurus was about 40 feet long and 10 feet tall at the hips. He weighed up to 5 tons. He walked on 2 legs. He had short arms and 3 fingers on each hand. In 1883, a rancher in Colorado named M.P. Felch found an almost complete Allosaurus skeleton on his ranch. Other fossils have been found in North America, Europe, Africa, and Australia. This “killing machine” was finding dinner in many different places.


C HAPTER 2

Allosaurus By: Trevor Ortmeier

Would you like to know about a meat eating dino that is slow? Well think of a Allosaurus. The Allosaurus had sharp teeth and sharp claws. The fierce of the Allosaurus ate meat. Allasaurus mouth was perfectly designed for chomping its meat. Allosaurus had a gaping bite that could fit around the thickest body parts of its prey. The Allosauruses meaning is “Different Lizard.� With its large skull, powerful neck, massive jaws, dagger like teeth, powerful limbs, and three clawed hands. When the Allosaurus lived, it was in the late Jurassic period. It weighed 4.5 tons. The first Allasaurus skeleton was found in Colorado, USA. It had burkey bones and heavy bones. It had very long legs and a long tail. It had 3 toes on each foot. It lived in Colorado, Montana, New Mexico, Oklahoma, South Dakota, Utah, and Wyoming. Allasaurus would try to eat anything.


C HAPTER 3

Apatosaurus By: Jenna Jennings

Do you know anything about dinosaurs? Well let’s find out! An Apatosaurus was one gigantic dinosaur. All Dinosaurus were the biggest land animals. Dinosaurs were mammals. Let’ see how much it weighs! The Apatosaurus weighs 33 to 38 tons. It’s height is 10 to 15 feet tall at the hips. The length is 70 to 90 feet long. It swallows stones to help push down its plant food. It does not chew! It’s fossils have been found in Colorado, Oklahoma, Utah, and Wyoming. They have been found without skulls!


C HAPTER 4

Brachiosaurus By: Karlene Bourek

A Brachiosaurus didn’t get attacked much in dinosaur days. Why? He spent most of his time in the water. He was too heavy to run fast. He stayed safe by spending lots of time in a lake. Brachiosaurus was up to 85 feet long and 40 to 50 feet tall at the head. He weighed between 33 and 88 tons. He was a plant eater who ate conifers, cycads, and ginkgos. He had pencil like teeth. Brachiosaurus walked on 4 legs. His front legs were longer than his back. He had a really long neck, a small head with nostrils on they top, and a long tail. Brachiosaurus fossils were first found in Colorado in 1900. His name means “arm lizard.” Brachiosaurus was a huge but gentle giant.


C HAPTER 5

Brachiosaurus By: Memphis Warren

Have you ever seen a dinosaur with nostrils on the top of its head? The Brachiosaurus has nostrils on the top of its head. The Brachiosaurus has a tiny head. The Brachiosaurus eats plants and not meat. The Brachiosaurus’s length is 80-85 feet long. The height was 23 feet tall at the hips. It weighed 33-88 tons. Fossils have been found in North America, Africa, Europe. It lived about 156-145 million years ago. The Brachiosaurus means Arm lizard.


C HAPTER 6

Brontosaurus By: Madelyn Gaughen Do you know what a dinosaur is? Well I had to pick a dinosaur and I picked the Brontosaurus. Fossils of the Brontosaurus have been found in Colorado, Oklahoma, Utah, and Wyoming in the USA, North America. The length of the Brontosaurus is 70-90 feet long. The Earth was ruled by the terrifying T-Rex and that peace loving vegetarian, the Brontosaurus, but the Age of Innocence really ended the day the Brontosaurus, the gentle giant of dinosaurs was revealed as a fraud. The skeleton Marsh found is still one of the most complete ever. It helped the Brontosaurus become one of the most identifiable and popular of all dinosaurs. In 1903 however scientists determined that Brontosaurus fossils were not from a new species, but from a dinosaur already discovered—the Apatosaurus. The name Brontosaurus continued to be featured on museum labels. Brontosaurus and Apatosaurus are simply different names for the same dinosaur.

Brontosaurus or Apatosaurus probably weighted 30 tons the weight of five elephants, but this was small compared to Brachiosaurus, which must have weighed up to 100 tons. An animal of this size would have needed to eat about 400 kilograms of plant material each day in order to stay alive. The Brontosaurus has 26 teeth on top and bottom. The Brontosaurus eat rock to help him to eat.


C HAPTER 7

Compsognathus By: Emma Claussen

Compsognathus was the smallest dinosaur ever. He was the size of a chicken and walked on three-toed feet with claws. His bones were hollow. Some scientists think he had feathers. Compsognathus had a tiny head and a pointed tail. He was only 10 inches at the hips and weighed about 6.5 pounds. This dinosaur was 28 inches to 4 ½ feet long but was a fast runner for his small size. His arms were very short. Compsognathus had very sharp teeth and was a meateater that ate lizards and insects. His fossils were found in Europe in the 1850’s. Compsognathus means “pretty jaw.” This does not sound like a very scary dinosaur.


C HAPTER 8

Compsognathus By: Colin Rhynalds

Although Compsognathus was the smallest dinosaur of them all, it was an extremely fast runner. Fossils have been found in two places in Europe, Cajuer, southern France Solnhofen in Bavaria, southern Germany. The Compsognathus was no bigger than a chicken. Its feet were like those of many birds today. The Compsognathus had three toes pointing forward and one toe pointing backward. Compsognathus was about the size of a chicken. Although they would not have met, Compsognathus and Ceratosourus both lived during Jurassic. Compsognathus weighs 6.5 pounds. Compsognathus length is 36 inches. Compsognathus height is 10 inches. It was named by John A. Wagner in 1859. It lived in Jurassic period. Compsognathus was first discovered by Dr. Oberndorfer in limestone deposits in the region of Bavaria. For such a tiny dinosaur, the Compsognathus had powerful legs and feet. Compsognathus help its strong hands and long claws. Compsognathus had huge eyes that helped it see clearly at night. Compsognathus lived during the late Jurassic period. Compsognathus means pretty jaw.


C HAPTER 9

Corythosaurus By: Zoey Haynes

The dinosaur I chose is very different because it had a head crest. The crest may have made sounds to call other dinosaurs. In some ways, Corythosaurus could talk. Corythosaurus had hundreds of teeth in his cheeks. He could eat lots of large plants and low-lying plants, too. He was one duck-billed dinosaur that lived right here in the USA. Corythosaurus was 30 feet long and 6 ½ feet at the hips. He weighed about 5 tons and had a stiff tail and thick body. His name means “helmet lizard,” which tells you about the bony crest on his head. Corythosaurus fossils were found in the western United States and in Alberta, Canada. He was named in 1914 by Barnum Brown. Corythosaurus was an interesting dinosaur to study.


C HAPTER 10

Dilophaurus By: Owen Ortmeier

Dilophauruses spit in your eyes. In the night the Diophaurus can blend in with the grass and trees. It’s enemies with the Pterandon. The Dilophaurus has a lightly built skull. The name meaning “double-crested lizard.” It lived in North America and Asia. The Dilophosaurus had two flattened semicircular crests on the head and has short arms with 3fingered, clawed hands and a long tail. It has powerful jaws that can bite flesh and bones. It can get as big as a baby Velociraptor. It can go fast as a jaguar.


C HAPTER 11

Diplodocus By: Damaris Hernandez

The length of the Diplodocus is 90 feet long. The height is 16 feet tall at the hips and their weight is 10-20 tons. They were longer then the Brachiosaurs, with long, whiplike tails. Much of that was its very long neck and tail. Diplodocus has a small lightly built head. All it’s teeth were the front of the mouth. These teeth were long, slender, and shaped like pencils. This tells us that Diplodocus probably ate soft plants. It was a gentle plant eater. Most of this length was made up from the very long neck and long whiplike tails. There were small bones below the backbone which had a piece that pointed forward as well as the normal piece that pointed back. D is for Diplodocus. This is one of the dangers dinosaurs that anyone has found. Many Diplodocus fossils have been found in the Rocky Mountains of the western USA.


C HAPTER 12

Edmontonia By: Kaden Juhl

Have you ever heard of a dinosaur that had spikes on its sides? It is the Edmontonia. . The plant-eating Edmontonia did not swallow all the food in its mouth at once. It stored some of it in its cheeks and ate it later. Spikes and plates helped bony skinned dinosaurs defend themselves against attacks by meat-eating dinosaurs. The Edmontonia weighs up to 3 tons. The Edmontonia height is 9 feet high. The Edmontonia lives in Alberta, Canada. During the Cretaceous period, from 144 to 65 milion years ago. The Edmontonia is a plant eating animal. The Edmontonia is the spikest dinosaur on the Earth.


C HAPTER 13

Galliminmus By:Grant Peters

Have you ever seen an ostrich? Well in the days of the dinosaurs, Galliminmus looked like today’s ostrich or a rooster. The small head of Galliminmus looked like a big pointed egg. Galliminmus’ tail looked rough and was pointed. Galliminmus was 13 to 20 feet long and 6.3 feet tall. It weighed 970 pounds. He walked on 2 legs. Gallimimus lived in Gobi Desert and was a meateater, but his jaw looked like a beak! One very interesting fact about Galliminmus is the fact that he was a theropod and very intelligent. It’s too bad he could not attend school. He might have been an A+ student.


C HAPTER 14

Giganotosaurus By: Kiersten Wardman

Did you know that a Giganotosaurus was bigger than a Tyrannosaurus Rex? A Giganotosaurus was 44 to 46 feet long, 13 feet tall at the hips, and weighed 8 tons. He was the longest meat eating dinosaur yet found. Giganotosaurus was a meat-eater with dagger like teeth with serrated edges. But his jaws were too weak to bite through dinosaur skin. He had to use his claws to kill his prey. Giganotosaurus had a big head with eyes facing sideways. It probably had a hard time seeing but had a good sense of smell. It’s brain was small, about the same size and shape as a banana. He had 2 strong legs and short arms. He walked on 2 legs. He used his tail to balance his huge head. Giganotosaurus fossils have been found in Argentina in 1994. His name means “giant southern lizard.� Giganotosaurus was a true giant. He was worthy of his own name!


C HAPTER 15

Gorgosaurus By: Ian Virka

Almost like the Tyrannosaurus and most other large Tyrannosaurus, Gorgosaurus can be described as having a massive head, large curved teeth, tiny twofingered front limbs, and powerful legs. Over 20 Gorgosaurus skeletons have been improved, making it the well-represented Tyrannosaurid in the fossil record. Gorgosaurus is a genus of carnivorous dinosaurs that reached 7 to 8 meters in length, and weighed 2.5 tons. They all had four limbs, thought many walked on two. It lives in Alberta, Canada. It ate plant eating dinosaur. The meaning of the dinosaur is Gorgon lizard.


C HAPTER 16

Iguanodon By: Aleya Bourek

Have you ever heard of something like a dinosaur that its name means Iguana tooth? Well you’re in luck because I know just the one, the Iguanodon! If it wanted to, it could go on all fours! It has a small head. The head is so soft, that it sometimes gets a hard spot! Also the tail is very stiff. 31 complete skeletonos of Iguanodon were found in a coal mine. Scientists now learned that a spike that they thought went on his head actually went on his thumb. Let’s find out about its length, height, and weight! The length is 30 feet high, which is 30 rulers stacked. Its height is 9 feet tall at the hips. Also it weighed 4-5 tons. Who wants to learn about what kind of teeth it had, what it ate, and where it lived. Guess what kind of teeth it had: tightly packed cheek teeth. Do you know that it ate cycads, conifers, and ginkgos. Do any of you know where it lived? I guess I’ll have to tell you wait

there is a very cool part. It lived in Europe, northern Africa here comes the cool part--in the U.S.A. That’s where we live. Its name means Iguana tooth. Someone noticed that it had teeth just like an Iguana then they called him Iguanodon. I know some cool facts about them like teeth and a few bones were found in 1822. Also it lived 135-125 million years ago. Plus it was the second described. Even today, scientists are finding out new things about these extinct animals. For example the now think Iguanodon had cheek pouches.


C HAPTER 17

Iguanodon By:Noah Post

There are a lot of famous people living today. Dinosaurs may be extinct but Iguanodon is still one of the most famous dinosaurs. It was also the second dinosaur ever named. Iguanodon was a big, heavy dinosaur. It weighed 4-5 tons and could grow up nine feet at the hips. It was 20-33 feet long. It had a strong back feet and a stiff long tail. Iguanodon was a plant eater that had a spike on each thumb. His beak was toothless but he had smooth tightly packed teeth in his cheek. Spikes may have helped Iguanodon in obtaining food. It was probably used for defense too. Fossils of this famous dinosaur have been found in southern England. Scientists have been studying Iguanodon ever since the 1820’s and still are. They named Iguanodon “Iguano tooth” because he had the spike on each thumb which was very unique. I would not want to meet up such a large dinosaur as Iguanodon with those spikes.


C HAPTER 18

Lambeosaurus By: Chris Lyda

Lambeosaurus had a strange looking head. He had a hatchet shaped crest with a bony spike at the back. His hollow crest was big, maybe even bigger than his skull. Lambeosaurus was the largest duck-billed dinosaur known so far. Lambeosaurus was 30 to 50 feet long and 7 feet tall at the hips. He weighed about 5.6 tons. Lambeosaurus had a long, stiff tail. He walked and ran on 2 legs unless he was looking for food. Then he walked on four legs. Lambeosaurus was a plant eater. He ate conifers, ginkgos, leeks, and magnolia leaves. Lambeosaurus fossils have been found in the western United States and in Alberta, Canada. He lived from 80-60 million years ago. Lambeosaurus means “Lambe’s Lizard.” He was named in honor of a Canadian paleontologist, Lawrence Lambe. That’s why a duck-bill dinosaur was called “Lamb”eosaurus.


C HAPTER 19

Megaraptor By: Bailey Rhynalds

About 15 years ago, fossils of a new dinosaur were discovered in Argentina. Paleontologist Fernando Novas found Megaraptor fossils in 1996. His name means “huge robber.” Megaraptor had a big head and curved flexible neck. He had a large brain and large eyes. He had sharp teeth and ate meat. Megaraptor had a 14 inch sickle-like claw on the second toe of each foot. The claw would help him grab his prey. Megaraptor was 20-26 feet long and about 6 feet tall at the hips. Scientists aren’t sure of the weight. He had a long thin tail that helped him balance and gave him fast turning ability.

Megaraptor was named in 1998. At that time they thought he was a raptor. Since then, they thought he was a raptor. Since then, scientists decided he wasn’t a raptor because raptors have wider fee. Whatever his name, Megaraptar was an interesting dinosaur to research.


C HAPTER 20

Muttaburrasourus By: Amy Murray

Muttaburrasaurus was one of the few dinosaur fossils found in Australia. It was named in 1981 after it was found by the Thompson River in Muttaburra, Sutralia. Its name means “muttaburro lizard” Muttaburrasaurus’ head looked very funny. It was small with a bony bump on the snout. His tail was like a really long lizard’s tail. Scientists aren’t sure whether he walked on 2 or 4 legs. Muttaburrasaurus was 24 feet long and 8 feet tall. He weighed between 1 to 4 tons. Muttaburrasaurus was mostly a plant eater but he may have eaten some meat. He had teeth that worked like shears. It would be fascinating to travel to Australia to learn about Muttaburrasaurus.


C HAPTER 21

Pentaceratops By: Natalie Knapp

If Pentaceratops was alive today, people might think he was like a rhinosaurus. The Pentaceratops had five horns on his face. Pentaceratops means “fivehorned-face.� Pentaceratops is the perfect name. The Pentaceratops was a herbivore. It probably ate low plants on the ground. It had flat cheek teeth and a toothless beak. Pentaceratops had a lizard shaped tail. His body was bulky and the four legs he walked on were like columns. He had the largest known skull found so far. Pentaceratops had a huge frill on the back of his head. It had knobby bones that made a fancy border. His head

could move easily. That probably scared other animals. Pentaceratops was 28 feet long and 10 feet tall. He weighed 13,000 pounds He lived in the Cretaceous period, about 75-65 million years ago. His fossils were found in New Mexico in 1923. Pentaceratops had the perfect name of a perfectly shaped dinosaur.


C HAPTER 22

Pteranodon By: Caleb Gomez

Have you ever heard something that looks like a Terodaotyl? If you had, it is called Pteranodon. It had 3 life cycles. 1. It had teeth and a tail in the first one. 2. It has over 5,000 ridges. 3. It had a large crest and a toothless bill. It was 6 feet long and only weighs 44 pounds. The only thing it ate was fish. It also had to swallow it whole. It could also eat eggs. It could likely live 90 years. Maybe 30 years for the first cycle, another 30 years for the second cycle, and a last 30 years for the last cycle. Or 3 maybe 10 years. It lived in North America. It was found in Kansas, England, and Europe.


C HAPTER 23

Saltopus By: Lara Dolezal

Do you want to learn about dinosaurs? Saltopus was a fast, tiny meat-eater. It was 2 feet long and weighed about 2 pounds the size of a small cat. The Saltopus was named by Fredrick von Huene. The Saltopus was named in 1920. The Saltopus name means Hopping Foot. It may have eaten mostly insects. The Saltopus lived from 222 to 225 million years ago. It walks on two feet. The Saltopus weight was 5 lbs. It is only 3 feet tall. The Saltopus has 5 fingers and only used three of them. Its fossils have been found in Europe. It is only 3 feet long.


C HAPTER 24

Saltopus By: Sydney Emanuel

Have you heard of Saltopus? Well, Saltopus was an early dinosaur that was very small, about the size of a house cat. Its name means “Jumping Foot” because scientists think it jumped. Saltopus was only 8 inches tall (20 cm) tall at the hips and its length was 2 feet. Its weight was about 2 pounds. Saltopus’s head was oval shaped and it’s tail was long. The tail helped it balance. Saltopus was a meat eater. It had sharp teeth that ate insects, small animals, and carrion. It also ate dead bodies of animals. Fossils of Saltopus have been found in Scotland. Only a very incomplete fossil has ever been found. Some scientists now think Saltopus was not really a dinosaur. He was probably just a close relative. I’m glad he’s not related to me!


C HAPTER 25

Spinosauruses By: Grady Harms

Have you ever heard of a dinosaur with nostrils on its head? Well the Spinosaurus does! The Spinosauruses teeth are straight not like the T-Rex. Spinosaurus arms are longer than the T-Rexes. Spinosauruses have five very sharp claws on both sides. Spinosaurs grew to be 40 to 56 feet long or 12 to 17 meters. The Spinosaurus stands on 2 giant legs with 2 or 3 sharp nailed toes. The Spinosaurus weighs 12 tons. It eats fish and other sea animals. It lived around lakes, swamps, and forests, and the sea! Spinosaurus means spine lizard, spiny lizard or thorn lizard!!!


C HAPTER 26

Stegosaurs By: Charlotte Leners

Stegosaurs means “plated lizard.” That is the perfect name for stegosaurs since there was a row of spiky plates along his back and tail. This popular dinosaur probably used the spiky plates as a lethal weapon. Stegosaurs’s teeth probably ate ferns, and other plant material. The Stegosaurs weight was 6,800 pounds and the dinosaur’s length was 26-30 long. Stegosaurs had a very small head and a tiny brain. His forelimbs were shorter than his hind limbs, giving him an arched look. He looked the size of a bus. Stegosaurs lived in North America in the late Jurassic period. He is a very popular dinosaur because his spiky tail is so interesting.


C HAPTER 27

Stegosaurus By: Lexi Montoya

The Stegosaurus has four spikes on its tail. The Stegosaurus can kill a Saltopus with its tail. The Stegosaurus is a herbivore. You can find a Stegosaurus in North America. The Stegosaurus walks on four legs. It is 26-30 feet long. Its name means “roofed lizard.� The Stegosaurus is one of the most popular dinosaur. The Stegosaurus was named by Othniel Marsh. It lived 156140 million years ago. It weighed 6,800 pounds. The Stegosaurus has small cheeked teeth. It has a small smooth head. It is 9 feet tall at the hips. The Stegosaurus has long spikes at the end of the tail.


C HAPTER 28

Triceratops By: Kaiden Jones

Triceratops has the perfect name. It means “3 horned face.� That is exactly what Triceratops has. He has 2 longer horns above his eyes, and one shorter nose horn. Triceratops has a large bone frill on the back of his head. Triceratops walked on 4 legs. His body was bulky and his tail was short. He was up to 30 feet long and was 7 feet tall at the hips. A triceratops weighed between 6 and 12 tons. Triceratops had small chewing teeth and a toothless beak. He ate plants that were close to the ground. Triceratops fossils have been found in western Canada and western United States. The first skull was

found in 1888 by John Bell Hatcher. At first, people thought it was an extinct kind of buffalo. Now we know that a Triceratops was most like a rhinoceros because it charged its enemies with its horn.


C HAPTER 29

Tyrannosaurus Rex By: Drew Hall

Tyrannosaurus Rex means “tyrant lizard king!� For a long time, people thought he was the biggest and fiercest dinosaur. Now others have been discovered. T.Rex is still on of the most popular dinosaurs we study. Tyrannosaurus Rex was 60 feet long, 15 to 20 feet tall, and he weighed 5 to 7 tones. He had a huge skull and a brain twice as big as other giant meat eaters like Giganotosaurus. There was a large area in his brain that helped him process smells. T.Rex was a meat eater. He had sharp teeth that grew up to 6 inches long. If a tooth broke off, it was automatically replaced. He could crunch the bones of his prey. If cars had been invented then, a T.Rex bite could have dented the metal.

T.Rex could stand up straight and run a high speed. His stiff tail helped him make quick turns. No wonder people thought he was the fiercest dinosaur. Tyrannosaurus Rex lived in the Cretaceous period. His fossils have been found in the USA, Canada, and Asia. Tyrannosaurus Rex was a fascinating dinosaur to research.


C HAPTER 30

Tyrannosaurus Rex By: Preston Knapp

Do you know a dinosaur with a name that means Tyrant lizard KING? Tyrannosaurus Rex means tyrant lizard king. Tyrannosaurus can run over 30 miles an hour. T. Rex only had two fingers. The T. Rex had a long tail. The T. Rex ate meat and walks on two legs. A T.Rex had fifty to sixty teeth. Their teeth were the size of a banana about six to 12 inches long. T. Rex had new teeth coming in all the time. A T. Rex was a meat eater. Animals that eat meat are called carnivores. T. Rex wasn’t the only dinosaur that ate meat. T.Rex was the largest dinosaur. A typical T. Rex weighed more than five tons. T. Rex at more than five tons of meat each week. It ate as much as it weighed. For such a big animal T. Rex had two little arms. T. Rex had sharp claws. A T. Rex could be 50 feet long from head to toe. He weighs up to 7 tons. A T. Rex has very sharp teeth. The T. Rex lives in Montana.


C HAPTER 31

Utahraptor By: Jordan Ondracek

Did you know a Utahraptor broke many teeth while hunting and had to grow new teeth? It had very sharp teeth and was quite the meateater. Utahraptor was fierce! I would not want to meet him. Utahraptor was pretty huge, about the size of an ice-cream truck, with enormous sickle-shaped claws. He was 16-23 feet long and 6 feet tall at the hips. He weighed about 1 ton and had a long tail. A Utahraptor had large eyes to spot its prey. Watch out! Utahraptor means “Robber from Utah� because fossils have been found in Utah, USA. He was named in 1993, not so long ago. I believe Utahraptor was one of the scariest of all dinosaurs.


C HAPTER 32

Velociraptor By: Travis Byrd

Velociraptor was a fierce meat-eater with rows of 80 sharp teeth. He terrified his prey, who didn’t have much of a chance to escape. Velociraptor stood on his back leg and attacked with his other leg. Velociraptor was only 5-6 feet long and 3 feet high at the hips. He weighed about 15-33 pounds. His tail was stiff and moved from side to side. Velociraptor’s head was average size but his brain was large in comparison to his body. Tyrannosaurus Rex was about 400 times heavier than a Velociraptor. Velociraptor’s name means “speedy thief.” His fossils were found in Mongolia, Russia, and China in 1924. About a dozen Velociraptor fossils have been found. One set showed he died in battle to the death with Protoceratops. I liked studying about Velociraptor but I’m glad I didn’t live in dinosaur days.


C HAPTER 33

Velociraptor By: James Kirschenmann

Would you like to know of a dinosaur that is the fastest running dinosaur? Well this dinosaur was a fast running, two legged dinosaur. That is where he got his name “Speedy Thief.” The Velociraptor weighs 15-33 pounds. It is 5 to 6 feet long and 3 feet tall. It did have a stiff tail that worked as a counterbalance and let it make very quick turns. Velociraptor’s brain was large compared to its body size. He could run up to 40 mph. He was one of the fastest and smartest dinosaurs. Velociraptor lived from 144 to 146 million years ago. In a hot dry environment, such like a desert. They were known to have been found in Mongolia in 1924.
