DINOSAUR DAYS.What's the difference between dinosaurs and monsters? I know there are no such things as monsters.DeAndre Watson, Age 8 Missouri You're right. Monsters are not real. They are creatures of our imaginations. Dinosaurs were living animals. We know they existed because they left fossils that scientists have studied. How did dinosaurs communicate? Jessica Spicer, Age 9 Delaware Many dinosaurs may have communicated by making sounds. Crested duckbilled dinosaurs left their sound-producing trumpet crests behind as fossils. Other dinosaurs may have communicated with roars and grunts, but we can't be certain because soft parts that make sounds, such as throats, rarely turn into fossils. Dinosaurs also may have communicated with smells, touch, and visual signs, such as a show of color not of the white race; - commonly meaning, esp. in the United States, of negro blood, pure or mixed. See also: Color or movements that had a certain meaning. I've heard that there were sea dinosaurs. Can you name them for me? Tony Zizumbo, Age 9 California There were many large sea creatures in dinosaur time, including giant reptiles such as Plesiosaurus Plesiosaurus (plē'sēəsôr`əs), genus of extinct predatory marine reptiles that arose in the Triassic period of geologic time and continued into the Jurassic and Cretaceous periods. , Mosasaurus, and Ichthyosaurus. But these animals are not called dinosaurs. You may be able to find a library book that names them all, but I don't have enough space to do that here! Is Brontosaurus Brontosaurus: see Apatosaurus. related to the elephant? Melissa Kelley, Age 9 Virginia Brontosaurus, which is known to scientists as Apatosaurus Apatosaurus (ăp'ətəsôr`əs, ā'păt'ə–), [Gr.,=deceptive lizard], quadruped saurischian dinosaur, estimated to be from 70 to 90 ft (21 to 27 m) in length and to weigh up to 30 tons (27 metric tons). , was not closely related to elephants. But I can see why you asked that question. Apatosaurus was a big plant eater, too, but he weighed as much as twenty elephants! Huge land animals need a lot of support for walking. So Apatosaurus, like the elephant, had wide, thickly padded feet. Did dinosaurs take care of their young? Evan Bates Evan Bates (born February 23, 1989 in Ann Arbor, Michigan) is an American ice dancer. He skates with Emily Samuelson. They are the 2005 US Novice national champions and the 2006 US Junior silver medalists. , Age 6 British Columbia British Columbia, province (2001 pop. 3,907,738), 366,255 sq mi (948,600 sq km), including 6,976 sq mi (18,068 sq km) of water surface, W Canada. Geography Some dinosaurs may have taken care of their young. We have evidence that the leg bones of some baby dinosaurs were too soft for the hatchlings to walk or run. Scientists think these babies needed a parent's care, just as many modern birds Modern birds (subclass Neornithes) are the members of class Aves that have survived into recent times and have coexisted with humans. Modern birds are characterised primarily by their toothless beaks, as most prehistoric bird groups possessed teeth. do. Write to Dino Don!
