Introduction

When there were no roads, no schools ,and no cars, much of the world was like the Amazon rainforest. Even Antarctica was covered in plants. Read this book if you want to learn about dinosaurs.

Chapter One: Mass Extinction Scientists think that the might have been caused by a volcanic eruption, the Ice Age, or an asteroid impact. The asteroid impact would have caused the mass extinction because the asteroid would have sent cloud of dust up into the air, killing all the plants, so the plant eaters (a.k.a the herbivores) would have nothing to eat. Then the meat eaters would have to eat each other.

Eventually there would be no meat eaters left.

The volcano eruption would have cause the mass extinction because it also would have cause clouds of dust to fly up into the air, and kill all the plants.

Also the lava from the eruption would have killed the dinosaurs.

The Ice Age might have caused the mass extinction because the dinosaurs would have died because not all dinosaurs can adapt to cold weather. Food became scarce so the dinosaurs could’ not eat.

Chapter 2:Fossils/Skin Imprints

Bones get fossilized by being compressed under rock for millions and millions of years.

The thigh bone of Brachiosaurus was about as tall as 6 grown men!

Skin imprinting is when the outlines of bumps on a dinosaur and the bumps go into soft ground. A carnotaurus was said to have bumpy skin.

A very famous battle of two dinosaurs was Protoceratops V.S Velociraptor. They both got killed by a really bad sand storm. The fossils were really tangled up from the battle. The Protoceratops skull was on the Velociraptor. It confused a lot of scientists.

Chapter 3: Kind of Dinosaurs

In this chapter you will learn about some of the kinds of dinosaurs.

Stegosaurus means “roof lizard”. The bundle of nerves near the base of it’s tail was thought to be a second brain. Stegosaurus uses its plate, the diamond shaped things on its back, to warm up or cool down. Scientist have found a hole the Allosaurus’ tailbone the size of a Stegosaurus tail spike.

Tyrannosaurus means “tyrant lizard king”.

Tyrannosaurus has four rivals: Giganotosaurus, Carcharodontosaurus, Mapusaurus, and Spinosaurus.

Tyrannosaurus Rex is a ​ carnivore​ .

Eoraptor was one of the first dinosaurs that ever lived. Eoraptor means “dawn lizard”.

Eoraptor is also a carnivore.

Non­dinosaurs include pterosaurs, plesiosaurs, and ichthyosaurs. There are four kinds of plesiosaurs: plesiosaurs, pliosaurus, nothosaurus, and elasmosaurus. Pterosaurs, plesiosaurs, and ichthyosaurs are usually piscivores​ .

Chapter 4: Carnivores

Carnivores are meat eaters. Types of carnivores are raptors, ceratosaurus, “birds”, giant meat eaters, and Tyrannosaurus.

Spinosaurus is the longest carnivore. Cousins of the spinosaurus are Suchomimus, Irrator, Baryonyx, and Acrocanthosaurus. They are all carnivores too.

Some carnivores eat all kinds of plants in addition to meat. The only ones who do are Ornithomimus and Oviraptors. Meat eaters only eat plant eaters. They don’t eat other carnivores but sometimes they eat dead carnivores if there is still meat left.

Deinonychus has two meanings. One is “false lizard” and the other is “terrible claw”. It’s a raptor that hunts in packs and is about 6 feet tall, 9 feet long, and weighs about 200 pounds, tiny, by dinosaur standards. They steal eggs from acrocanthosaurus and hunt eggs of almost any dinosaur. Deinonychus can take down Sauropods, duckbills, and hadrosaurus. This is a powerful dinosaur and can take down one dinosaur the size of Burr School.

Ceratosaurus is related to coelophysis, carnotaurus, and ceratosaurus itself. This dinosaur has three fingered hands and horn on it’s nose. It lived in the ​ Jurassic​ period, the second period of the dinosaurs.

Siamotyrannus has two fingered hands and knife like teeth to break bones. Most of them lived in the ​ cretaceous​ but some of them lived in the Jurassic time. They usually eat horned dinosaurs or duck billed but they can take on almost anything. Hunting is dangerous. Every hunt might be their last.

Spinosaurus has a spine but not all it’s cousins have a spine. It has a crocodile like mouth and two long arms which is an unusual feature. Their tail is long and heavy to counterweight the other parts of its body. It’s the longest meat eater ever but it’s not the heaviest. Because the legs are so far back they sometimes walk on four legs.

Chapter 5: Herbivores

All herbivore eat plants. Almost all herbivores have defenses. There are different types of herbivores. You will meet one on the next paragraph….

There are two types of marginochelians, ceratopsians and pachycephalosaurus. The ceratopsians include small ones like psittacosaurus and protoceratops and large ones like triceratops and pentaceratops.

The pachycephalosaurus have a tiny relative called micropachycephalosaurus and big ones like pachycephalosaurus.

The duck­bills are divided into two groups crested and non­crested. The crested branch includes dinosaurs like corythosaurus and parasaurolophus. The non­crested branch includes dinosaurs like muttaburrasaurus and edmontosaurus

Conclusion

Now that you’ve read this book , you are an expert on the Mass extinction of the dinosaurs, fossilized bones and the types of dinosaurs and what they eat. Visit a public library and go to the science section and check out a book about dinosaurs to learn more.
