DinosaursDinosaursDinosaurs

Why should we study dinosaurs? Why should we study dinosaurs? They are, after all, animals that disappeared about 60 million years before

the earliest human. What makes dinosaurs important to us now? Not only do they capture our imagi-nation as few animals do, they are also huge, mysterious, scary, and fascinating. Paleontologists, scientists who study the fossils of dinosaurs, learn about the connection

between dinosaurs and animals of today. By studying dinosaurs, we can learn how they lived and come closer to understanding how they became extinct. This is

an important lesson to learn as today we are faced with protecting many endangered animals, such as the manatee, whooping crane,

orangutan, and grizzly bear.

We have access to more information about dinosaurs than ever before. Scientists have made new discoveries in Africa, Asia, Antarctica, and the United States. New pow-erful electron microscopes now show tiny details of dino-saur remains. High-powered drills enable scientists to dig deep into the earth to find fossils. These new tools and

others like them allow scientists to learn things about dino-saurs they couldn’t have discovered before.

For example, did you know that some dinosaurs sat on a nest of eggs to hatch their babies? Also, we’ve recently learned that dinosaurs were probably not warm-blooded like mammals or cold-blooded like reptiles of today but somewhere in between. The tracks of dinosaurs show us that some lived in herds and nested together.

Dinosaurs ruled the earth about 225 million to 65 mil-lion years ago during a time known as the Jurassic and Cretaceous periods. The continents that are now separate were all together at that time, so dinosaurs could walk everywhere. They shared the land with other animals, marine reptiles lived in the seas, and primitive birds flew in the skies. The world was much hotter, wetter, more humid, and filled with many plants. These were dangerous times for all creatures that might be eaten or trampled to death.

We’ll take a close look at dinosaurs and marvel at these awe-inspiring creatures. Dinosaurs rock, and you know it!

Dinosaurs rock!There are lots of dinosaurs and they are as different as night and day. Paleontologists (the scientists who study dinosaur fossils) learned much of what they know about dinosaurs from bones, teeth, claws, and horns – all of which turned to stone and became fossils. Some of their soft parts, such as skin, hearts, and brains seldom formed fossils, so paleontologists have to make some educated guesses about dinosaurs.

Piecing these parts together tells us many things about dinosaurs. The bones show the size of the dinosaur. The largest were 100 feet long and weighed about 100 tons while the smallest were only two feet long and weighed about six pounds. Some dinosaurs walked upright on two feet while others walked on all fours. Long-necked dinosaurs were able to reach far up into trees for their meals, while those with strong necks were able to rip the flesh of their prey with a twist and a jerk. A bill like a duck’s was good to have for getting leaves from plants.

The teeth show us which dinosaurs ate meat (carnivores) and which pre-ferred plants (herbivores). Sharp teeth were for slicing and cutting, while flat teeth were for crushing and grinding. Some dinosaurs had many sets of teeth, too.

Some dinosaurs used their tails for clubbing their attackers. Other tails were used for better balance. Horns were good weap-ons, and dinosaurs used spikes, or armor-like skin, for defending themselves. Some of the smaller dinosaurs were speedy, moving at up to 45 miles per hour, while the gigantic ones lumbered along as their feet pounded the earth. Crested dinosaurs made trumpeting sounds while some dinosaurs roared or managed only a hissing sound. Their brains were different, too. A large brain probably meant the dinosaur had better senses and control of

their movements. Small-brained dinosaurs had little brainpower.

Learning activities Learning standard: locating diverse places, summarizing, giving oral reportsDinosaur fossils have been found recently in Africa, Asia, and the United States. Search the Houston Chronicle for datelines of countries or cities in Africa and Asia or of cities in the United States. Make a list of the places.

Animals are often in the news. Look through your eEdition for any stories about animals. Read the article and underline the important parts of the story. Write a summary of the story or give a short report in front of your class.

Dinosaurs are a large group of extinct ________ that lived millions of years ago. For more than 150

million years – a huge span of time – dinosaurs ruled the land. The word “dinosaur” means

“terrible ____________,” and these animals came in a huge variety of shapes, ______, and colors, from

long-necked plant-eaters that weighed 100 tons to small-legged _____-eaters no bigger than a rooster.

So far, _______, scientists who study prehistoric animals, have found almost 400 different kinds

of dinosaurs in virtually every corner of the globe, from the Mamenchisaurus in China to the

Iguanodon in England to the Hadrosaurus in Haddonfield, _________________. And these creatures

had all kinds of cool features they used to find food and defend themselves: horned

heads, _______ tails, armored plates, sharp ______, massive teeth, parrot beaks, _________ necks,

ostrich legs, and so on. We know that dinosaurs existed because we find their ____________, the

remains they have left behind. Examples of fossils include bones, eggs, skin

impressions, ___________, and more. And every time we find a new dinosaur, we learn something

new. There are so many mysteries about dinosaurs: what colors they were, what they _________ like,

what each one ate, and, of course, the big mystery, why they became _____________. So we’ll keep

digging into the Age of Dinosaurs and learn a lot about these magnificent prehistoric creatures.

Dinosaur Meaning Feature

Dinosaur NamesA dinosaur is named by the scientist who discovers it. The name often includes Latin and Greek root words that describe the animal, like Triceratops meaning “horned face” or Brontosaurus meaning “thunder lizard.” Sometimes, the name tells us where it came from, as Edmontosaurus was a plant-eating duckbill from the Edmonton region of Canada and Montanaceratops is a cousin of Triceratops that came from, well, can you guess? Finally, some dinosaurs are

named after people, Othnielia for famed dinosaur hunter Othniel Marsh and Avaceratops for a woman, Ava, who stumbled upon a dinosaur skeleton on her Montana ranch and called a paleon-tologist. If you found a dinosaur, what would you name it?

Learning in the NewsLearning standard: understanding fact and opinion, writing for fluency

Look at the stories on the front page of the Chronicle. See how the important stories are written. Write a two-paragraph story about the day you found a dinosaur. Tell who found it, where, how, when, what you named it, and why. Then see whether you can find another story in the eEdition that has those same five facts – who, what, when, where, and why.

The time machine landed smack in the swamp with a loud “SPLASH!” The

three of us stared at each other in surprise. We were in the machine

for what seemed like only seconds, but we had traveled back in time to the Age of Dinosaurs.

Peeking out the window, I could see an amazing landscape, filled with lush greenery and big leaves. I could hear animal sounds everywhere – cackling, shrieking, growling, bellowing. I think our splash surprised everything living in and around the swamp.

We all smiled, and Laura said, “Let’s get to business.” We unbuckled ourselves, threw on our jungle helmets and backpacks, and opened the cabinet to hand out our rifles. Some people hunt deer, some hunt bears, some even hunt lions and tigers. We landed in the Cretaceous Era 65 million years ago to do something really different. We were hunting dinosaurs.

I threw open the latch, and we stepped into the bright ancient sunlight. SUDDENLy,

The Record FiercestAThe Giganotosaurus is the fiercest of all the dinosaurs, with its razor-sharp teeth and its size (slightly larger than the formerly fiercest Tyrannosaurus Rex). Fossils of the Giganotosaurus found in Argentina show a carnivore (meat-eater) with a powerful body and huge tail.

Smallest VThe Compsognathus was a tiny but fast-moving dinosaur about 2 feet long and weighing about 6 1/2 pounds. It had sharp claws and a long neck to make catching insects easy.

Longest NeckBMamenchisaurus had a neck that was 49 feet long. The long neck allowed the herbivore, or plant-eating Mamenchisaurus, to reach high up into the trees for food to enjoy a hearty meal.

Heavyweight ChampWeighing in at more than 100 tons is Seismosaurus, also known as the Earthshaker. The earth trembled as Seismosauras’ feet came crashing down with each step. The previous record holder was Brachiosaurus at 50 tons.

BrainiacTroodon was a smallish dinosaur at about 6 feet long, but it had a rather large brain and was probably one of the most intelligent. That might account for Troodon’s keen eyesight and use of its well-developed hands.

Learning activities Learning standard: recognizing words, writing creatively and for fluency

Biggest, smallest, slowest, fastest, smartest, dumbest – these are the extreme words that describe dinosaurs. Look in your eEdition for other extremes for the day. Make a list of the words you find. Make a drawing of a dinosaur illustrating one of the extremes. Dinosaurs capture the imagination, especially in young people. Do an eEdition search to see whether there are movies or television shows about dinosaurs. Are there advertisements using dinosaurs to promote the product? Then create your own ad to promote a movie, television show, or product using your favorite dinosaur.

Least SmartWith a brain the size of a walnut, Stegosaurus ranks at the bottom of the class. Its tiny brain and large body gave it the ability to find food, reproduce, and defend itself. Stegosaurus was a harmless plant-eater that couldn’t even run and hide from its attackers.

HungriestBrachiosaurus weighed 50 tons and had an enormous appetite, eating about 500 pounds of vegetation every day. Now there’s a meal fit for a king or queen.

“Tail-gaiting”Ankylosaurus, about 35 feet long, had an enor-mous clubbed tail with two lumps of solid bone that could knock down even Tyrannosaurus Rex.

My What Big Teeth you HaveCarcharodontosaurus, with its large head and sharp fangs, probably had the largest teeth to eat the flesh of its prey. And when a dinosaur’s teeth were broken or worn, they simply grew a new replacement set.

Not every big and extinct reptile was a dinosaur. In fact, during the Age of Dinosaurs, the land teemed with reptiles that, while related to dinosaurs, were not dino-saurs.

Take Pteranodon (pronounced ter-ANN-o-don), for example. A flying reptile, Pteranodon flew during the Age of Dinosaurs, and while it may have been eaten by dinosaurs, it was not a dinosaur. So this time period is better called the Age of Reptiles, as reptiles were the dominant land animal at the time.

Snakes, lizards, turtles, and crocodiles are the major groups of reptiles alive today. But back then, there were many, many more groups of reptiles. They all shared several traits, one being arrangements of their bones and skeleton, another being their blood. Today’s reptiles are cold-blooded, but back in the Age of Dinosaurs, the dinosaurs were probably somewhere in between cold-blooded and warm-blooded. Can anyone in your class explain what “cold-blooded” and “warm-blooded” mean?

The Dinosaur Rules

11

Here are the dinosaur rules.

If an animal fits all three of these statements, then it is a dinosaur. If not, oops, it’s a different kind

of reptile, or something else altogether.

1. All dinosaurs live in the Mesozoic Era, between 225 million and 65 million years ago. If it is an

older creature, or a younger one, it is not a dinosaur.

2. All dinosaurs lived on land.None could fly, and none lived in the ocean.

3. All dinosaurs walked upright, belly off the ground, just like elephants and rhinos.

This is the key to a dinosaur’s success—their upright stance allowed them to be faster and more mobile

than other reptiles at the time. Any belly-dragging creature is a different animal—

definitely not a dinosaur.

A. Dimetrodon. With its finned back and sharp teeth, this one is included in many dinosaur books. It lived 230 million years ago and had a sprawl-bellied posture like that of a large crocodile.

B. Pteranodan. One of the flying reptiles, alive 150 million years ago in Africa.

C. Allosaur. A giant meat-eater that lived 150 million years ago.

D. Ichthyosaurus. A fish-eating dolphin-like animal that swam during the Mesozoic Era.E. Wooly mammoth. A large, hairy, extinct elephant that lived during the Ice Age 100,000 years ago.F. Elasmosaurus. An ocean-living reptile that lived 80 million years ago.

Now try the three rules with the animals below. Only one of the six creatures here is a dinosaur. Can you use the rules to figure out which one?

correct. How did you do?

Chalk-a-saurusChoose a very large dinosaur, such as Brachiosaurus, Diplodocus, or Tyrannosaurus rex. Use chalk and library books to draw a life-sized version of this dinosaur on the asphalt of your schoolyard. (Make sure it’s not a rainy day.) When you’re done, give tours of your creation to groups.

Dino-LengthsChoose a variety of different sized dinosaurs, such as the following: Compsognathus, Stegosaurus, Triceratops, Ankylosaurus, Allosaurus, and Diplodocus. Research the lengths of these dinosaurs from two or three sources to get ideas for how long each one was. Using different colored electri-cal or craft tape, measure out their lengths on a hallway floor and use the tape to show the length of that dinosaur. Draw pictures of each dinosaur and mark the tape clearly so everyone knows which dinosaur is which.

King of the DinosaursHave your students elect the “king of the dinosaurs,” the favorite dinosaur of students in your grade, or even your whole school. Draw up a ballot, and ask students to vote, either by a show of hands or by writing on paper ballots, for their favorite dinosaur. The group assigned to this project conducts the poll, then creates a poster-sized bar graph that interprets the results.

TimelinesDinosaurs lived for a very long time, the first ones dating to more than 225 million years ago and the last ones disappearing 65 million years ago. In the school’s hallway, create a timeline using string. One end of the hall is the current year and the other end is 225 million years ago, at the beginning of the Age of Dinosaurs. Use your math skills to figure out what year marks the halfway point of the hallway as well as the one-quarter and three-quarter points.

Then find a sample of different dinosaurs that lived at different ages, and place drawings with their names at correct points along the timeline. Also, fill in the correct times that the following events occurred: America’s independence, Columbus’ voyage, the Ice Age, the first humans, the first mam-mals, the first birds, and the first flowers.

Give tours of your timeline to fellow students.

Dino-RamasCreate a dinosaur museum of clay dinosaurs representing those that lived at the same time and in the same place as each other. Use library books to assist you, look for large drawings of groups of dinosaurs living in the same environment. Have groups pick one diorama to bring to life, and arrange them in the hallway on tables as a small dinosaur museum.

One diorama might include Tyrannosaurus and Triceratops, another Allosaurus, Stegosaurus, and Apatosaurus. Other books will show you other examples of dinosaurs that belong together.

Dinosaur Day

Imagine your class celebrating Dinosaur Day, a day when your class presents a variety of dino-saur projects for each other and the rest of the school. Break into small groups selected by your teacher and tackle one of the projects below. When all the projects are gone, have a Dinosaur Day, a day when your class gives tours of the exhibits it creates. Have fun!

Look in the Lost and Found section of the eEdition. you won’t find ads for dinosaurs, but make a list of some of the interesting items. Then create your own ad for a lost or found dinosaur.

Extinction:The Big MysteryRead the paragraph below, to yourself or aloud, as your teacher recommends. Then answer the questions below on the lines provided.

Dinosaurs lived for millions of years, and millions of dinosaur fossils have been found all over the world. One of science’s biggest mysteries has been what happened to the dinosaurs. Something happened, the Earth changed, and dinosaurs became extinct. Exactly what happened has been the subject of a long debate.

We know that rocks older than 65 million years contain fossils of dinosaurs. Rocks younger than that age, however, have no dinosaur fossils at all. We know that the last dinosaurs vanished 65 million years ago.

We also know that many other creatures vanished at the same time as dinosaurs. The oceans were home to large reptiles called plesiosaurs, mosasaurs and ichthyosaurs, as well as squid-like animals called ammonites. All of these vanished when the dinosaurs died out. So did ptero-saurs, the winged cousins of dinosaurs. So did families of small plankton floating on the ocean surface. There were big changes then.

Since the 1800s, many theories have come up to explain the mystery of dinosaur extinction. They grew too tall. Mammals ate all their eggs. The planet got too hot, or it got too cold. No theory worked, because any good theory should also tell us why ammonites and pterosaurs died too. And any good theory should also help us understand why turtles, fish, opossums, snakes, alligators, ants, and birds all survived.

In the late 1970s, it was suggested that an asteroid or comet from outer space smashed into the earth 65 million years ago, causing tidal waves to upset the oceans and raising a massive dust cloud that darkened the skies. One good thing about this theory is that we can find evidence for it: There is an impact crater in Mexico that dates to the right time, and a rare metal found in asteroids has been found in rock at the end of the Dinosaur Era.

Many scientists think this is what happened. But not all. Some scientists even say that if the asteroid hit, dinosaurs had already died out.

The debate continues. Dinosaur-hunters still search for clues. One day we may know for sure, but not yet.
