Dinosaurs dominated Earth for over 165 million years. Humans have been around for only 2 million years. [11] 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] A newborn human baby has a bigger brain than most adult dinosaurs had. Whales and dolphins have the biggest brains of all living animals. [8] Plant-eating dinosaurs often lived together for protection, like herding animals today do. The herds ranged from just a few adults and their young to thousands of animals. [3]

As you can see, this eBook has everything that your students need to know about dinosaurs at this age. You can use this resource in class as an activity, and you can also advise them to read this at home to continue studying. This beautifully illustrated eBook features a ton of dinosaurs in their habitats and some key information. 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.Colin Mochrie • The first dinosaurs that appeared during the Triassic Period 230 million years ago were small and lightweight. Bigger dinosaurs such as Brachiosaurus and Triceratops appeared during the Jurassic and Cretaceous periods. [8]

The earliest named dinosaur found so far is the Eoraptor (“dawn stealer”). It was so named because it lived at the dawn of the Dinosaur Age. It was a meat eater about the size of a German shepherd. The first Eoraptor skeleton was discovered in Argentina in 1991. However, another dinosaur has recently been found in Madagascar that dates as being 230 million years old. It has not been named yet. [8] These dinosaur fact files are a fantastic tool for helping children to develop their reading skills and they can learn lots of fascinating facts about their favourite dinosaurs. They have been designed by teachers to save you time and help you to provide a fun and engaging learning experience for students. The mass extinction of the dinosaurs and other animals that took place 65.5 million years ago is known as the Cretaceous-Tertiary extinction event, or the K-T event. Scientists have several theories for this extensive die-off. One theory proposes that small mammals ate dinosaur eggs until the population became unsustainable. Other scientists believe the cause was dinosaurs’ bodies becoming too big for their small brains, a great plaque decimating the population, starvation, or climate change. [11] Seymour Simon, whom the NY Times called "the dean of [children's science:] writers," is the author of more than 250 highly acclaimed science books (many of which have been named Outstanding Science Trade Books for Children by the National Science Teachers Association).

The oldest known dinosaur is Saltopus. A small carnivore, this dinosaur lived over 245 million years ago. [2] 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: The Smithsonian Museum of Natural History has a spectacular virtual tour of its exhibits – which include many prehistoric fossils and recreations of dinosaurs. The smartest dinosaur was probably the Troodon (“tooth that wounds”). It had a brain the size of a mammal or bird today. It also had grasping hands and stereoscopic vision. [11] By using resources like this, you may be instilling a love for these creatures in your students. Who knows? Maybe the next big palaeontologist is in your class!

Did you know that the largest dinosaur was longer than a tennis court but its babies were no bigger than a newborn human baby? That the smallest dinosaur weighed less than a teaspoon of sugar? Or that the largest flying reptile was as tall as a giraffe, with wings the size of a small plane? Children aged 9+ will love all these facts and more, presented either with jaw-dropping CGI illustrations or eye-popping photography - plus additional boxes feature diagrams that make information easy to understand. Like birds and reptiles today, dinosaurs built nests and laid eggs. Some even fed and protected their babies. [10] The biggest plant eaters weighed over 100 tons • Some of the biggest plant eaters had to eat as much as a ton of food a day. This is similar to eating a bus-sized pile of vegetation every day. [8] Your pupils can enjoy finding out about dinosaurs and hone their reading skills at the same time. This resource will also explain to children how the dinosaurs became extinct and introduce them to the different types of animal diets.Snakes and lizards shed their skin when they grow. Researchers believe that dinosaurs may have done the same. [8] When children read these fact files, they can learn lots of interesting information all about dinosaurs. They can find out: BBC Teach has a useful set of videos and resources to support teaching a dinosaur topic in EYFS, KS1 and KS2. 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] Measuring 50 feet, Liopleurodon was the biggest aquatic reptile, half the size of the blue whale. [4]

This unbelievably fascinating dinosaur book for children will teach you all you need to know about prehistoric animals, like which dinosaur had the sharpest teeth, the longest claws, the smallest brain, the largest droppings, and lots more! George and Levi Sternberg find the first impression of dinosaur skin, belonging to an Edmontosaurus, in Wyoming.Dinosaurs had different self-defense mechanisms. Some, like meat eaters, had sharp teeth. Plant eaters had long horns or sharp spikes. Other dinosaurs were covered in bony plates. [10] People have only been on Earth about 2.5 million years. Dinosaurs lived on Earth for about 160 million years, which is about 64 times longer than people been around. [5] The only known example of the giant sauropod Seismosaurus appears to have choked to death on a stone it was trying to swallow to use as a gastrolith. [5] The first known American dinosaur was discovered in 1858 in the marl pits in Haddonfield, New Jersey. Although other fossils were previously found, they were not correctly identified as dinosaur fossils. [11]
