Product Information

If you require a different version of this Dinosaur eBook, we have the following alternative versions available for your convenience: What's the world's weirdest dinosaur? What was the smallest dinosaur? Are birds really related to dinosaurs? Explore the enormous and surprising world of dinosaurs here, including dinosaur diet, types of dinosaurs, where dinosaurs lived, the wildest dinosaurs, and much more.

Scientists believe that some dinosaurs were cold blooded, others warm blooded, and still others not fully one or the other. Small meat eaters may have been warm blooded. Plant eaters who were not as active were probably cold blooded. A warm-blooded animal needs about 10 times more food than a cold-blooded animal the same size. [11] Reading is a great way to gather information and learn about new things. Now that you have introduced the topic of dinosaurs to your students, use this non-fiction Dinosaur eBook to help advance your students’ learning! In this book, you will find a lot of information about dinosaurs and the world they lived in. Have a look at the content you will find in this resource:

Humans’ eyes face forward so that they can see in 3D. Plant-eating dinosaurs, like the Triceratops, had eyes looking out to each side, so they could watch for danger while they fed. [10]

Scientists can guess how fast a dinosaur walked or ran by looking at the gaps between its footprints. [5] The smallest dinosaur egg ever found was only 3 centimeters long and weighed 75 grams. It is not known what kind of species it came from. The largest dinosaur eggs ever found belong to a meat eater in Asia called segnosaurus (“slow lizard”). The eggs are around 19 inches long. [11] Ichthyosaur babies were born tail-first. Th they had been born head first, they would have drowned before they could reach the water's surface to take their first breath. [5]Baby Mussaurus (“mouse lizard”) are the smallest dinosaur skeletons ever found. They would fit inside a shopping bag. [8] These fact files are available in three different reading levels to support your teaching as well. The first level is a simple word and picture matching activity while the other fact files involve reading at two levels.

All the levels feature original, hand-drawn illustrations of the dinosaurs to aid with visual learning. These beautiful images are especially helpful for young readers because they can use the illustrations to aid their reading. A Dinosaur Word Mat would be great to introduce learners to the important vocabulary of the topic. This one can be used as a visual aid as well as vocabulary reference for students while they are working on their activities.

Some scientists believe that Tyrannosaurus rex may have been able to run as fast as 18 mph (28 km/h). Other scientists believe it could not run at all because it was so big. [10] Modern birds and reptiles have a single body opening for urination, defecation, and reproduction: a cloaca (Latin for “sewer”). Paleontologists believe that dinosaurs were similarly designed and reproduced by pressing their cloacas together in a “cloacal kiss.” Additionally, some dinosaurs may have had a penis like some birds do or other “intromittent organs” like crocodiles. Paleontologists believe a Tyrannosaurus rex male reproductive organ might have been up to 12 feet in length. [6] Gideon Mantell (1790-1852) put Iguanodon's thumb claw on top of its nose • Paleontologists are not perfect. For example, Gideon Mantell (1790-1852) put Iguanodon’s thumb claw on top of its nose. It stayed that way for 40 years. Edward Cope (1840-1897) reconstructed Elasmosaurus (“thin plate”) with its head on the end of its tail. Until recently, Apatosaurus (or Brontosaurus) appeared in museums with the head of Camarasaurus (“chambered lizard”). [10] Most meat-eating dinosaurs had bones filled with air. Though their bones were huge, they weren’t as heavy as they looked. Birds have the same kind of hollow bones. [10] Plant-eating dinosaurs may have contributed to global warming by passing gas • Sauropods were the tallest animals that ever lived. Some were more than twice the height of a giraffe. [4]

Tyrannosaurus rex ate up to 22 tons of meat a year. It had jagged teeth 6 inches (15 cm) long. It couldn’t chew, so it swallowed its food in large chunks. [2] He taught science and creative writing in elementary and secondary schools and was chair of the science department at a junior high school in the New York City public school system before leaving to become a full-time writer. "I haven't really given up teaching," he says, "and I suppose I never will, not as long as I keep writing and talking to kids around the country and the world." George and Levi Sternberg find the first impression of dinosaur skin, belonging to an Edmontosaurus, in Wyoming.Parasaurolophus had a crest that looked like half of a trombone. The male’s crest was up to 6 feet (1.8 m) long, which was the biggest out of all the dinosaurs. [8]
