First Facts Dinosaurs

Product Information

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] Meat-eating dinosaurs are known as theropods, which means “beast-footed,” because they had sharp, hooked claws on their toes. In contrast, plant-eating dinosaurs tended to have blunt hooves or toenails. [4]

In the original Jurassic Park, Michael Crichton wanted John Hammond, the park overseer, to be a dark "Walt Disney." [9] In the 1993 movie Jurassic Park, the sound of the T-Rex's footsteps was the sound of cut sequoias crashing to the ground. [9] 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 dinosaur with the longest claws was the Therizinosaurus (“reaping lizard”). Its claws were up to 3 feet (1 m) long. [10]

Some dinosaurs were carnivores, which means they ate meat. This would include other species of dinosaurs and also birds and insects. The most famous example of this type of dinosaur is the T-Rex, one of the most effective predators in history. While dinosaurs had the same set of leg bones, some had feet like a rhinoceros, elephant, bird, or a pig. The biggest footprints ever found were 3 feet (1 m) across and 4 feet long. Millipedes have more legs than any other animal—up to 750. [8] Struthiomimus (“ ostrich mimic”), as well as other small hunters, made high-pitched, screechy noises similar to an ostrich. [8] Dinosaurs lived during a period of Earth’s history called the Mesozoic (“middle life”) Era. They lived during all three periods of this era: the Triassic, Jurassic, and Cretaceous. [2]

Ben and Caroline Bingham, eds. Dinosaurs: A Visual Encyclopedia. New York, NY: Dorling Kindersley Limited, 2011. Seymour Simon writes and photographs nature from his hilltop home in Columbia County in upstate New York, where he lives with his wife Liz Nealon. Dinosaurs may not be extinct • Many scientists believe that birds are dinosaurs and, therefore, dinosaurs are not actually extinct. [10]Dinosaurs dominated Earth for over 165 million years. Humans have been around for only 2 million years. [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). 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] 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]

One of the weirdest dinosaurs is the Suzhousaurus. Looking like a giant rat, this odd dinosaur also had a furry body, which suggests it is a distant ancestor of the giant ground sloth. [1] Dinosaur skulls had large holes or “windows” that made their skulls lighter. Some of the largest skulls were as long as a car. [4] Sue, the largest, most complete, and best preserved Tyrannosaurus rex skeleton ever discovered, is found in South Dakota. 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]

Baby Mussaurus (“mouse lizard”) are the smallest dinosaur skeletons ever found. They would fit inside a shopping bag. [8] 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 oldest known dinosaur is Saltopus. A small carnivore, this dinosaur lived over 245 million years ago. [2] Measuring 50 feet, Liopleurodon was the biggest aquatic reptile, half the size of the blue whale. [4] The tallest hunter was the Deinocheirus (“horrible hand”). Its head was up to 20 feet (6 m) off the ground. [10]
