Dinosaur, the common name given to a group of reptiles, often very large, that first appeared roughly 245 million years ago and thrived worldwide for nearly 180 million years. It was a dinosaur tail", "Sustained miniaturization and anatomical innovation in the dinosaurian ancestors of birds", "Footprints pull origin and diversification of dinosaur stem lineage deep into early Triassic", "The Cretaceous–Tertiary biotic transition", "No Paleocene dinosaurs in the San Juan Basin, New Mexico", https://simple.wikipedia.org/w/index.php?title=Dinosaur&oldid=7132476, Creative Commons Attribution/Share-Alike License.

Dinosaurs aren’t the only thing to have gone extinct—here are 14 facts about animals that have gone the way of the dodo in the past 100 years. and Brett-Surman M.K. Eoraptor probably resembles the common ancestor of all dinosaurs;[15] its traits suggest that the first dinosaurs were small, bipedal predators. Nesbitt S.J. [16] The discovery of primitive, pre-dinosaur,[17] types in Middle Triassic strata supports this view. Over 500 different genera of dinosaurs are known. An online magazine that blah blah blah blah. Early saurischians were similar to early ornithischians, but different from modern crocodiles.

Many scientists dismiss the "Paleocene dinosaurs" as re-worked, that is, washed out of their original places and then re-buried in much later sediments. [6] They evolved from the earliest theropods during the Jurassic. Dinosaurs were doing well and could have continued to dominate Planet Earth if they had not been wiped out by an asteroid, new research has found. Dinosaurs, dinosaurs, some gave fear. Against a backdrop of nature, which is clearly real, we see dinosaurs that are scarcely less real. Birds are the closest living relatives of the dinosaurs. Within these first dinosaurs, you will find well-known names like the Brachiosaurus, Brontosaurus, and the Apatosaurus (formerly the Brontosaurus). Therefore, the idea of warm-blooded dinosaurs insulated by feathers led to the idea that they were more active, intelligent and faster runners than previously thought.[19]. It was the smaller sized meat-eaters that may have evolved into birds. Find out facts about dinosaurs, including Diplodocus and Stegosaurus, and uncover what science is revealing about the appearance and lives of these prehistoric animals. Dinosaurs are proven to be not as efficient thinkers than humans. Linking the evolution of body shape and locomotor biomechanics in bird-line archosaurs. Some of their bones were found much earlier, but were not understood. The following is a simplified list of dinosaur groups based on their evolution. They were the dominant land animals of the Mesozoic era. This might happen if there hasn’t been much rain and so there are not as many plants around to eat. The Pteranodon's wings went FLAP, FLAP, FLAP. William Buckland, Gideon Mantell and Richard Owen saw these bones were a special group of animals. There has been much scientific debate regarding the evolution and purpose of Spinosaurus' sail. They were the largest animals to ever walk on dry land. (Each child has a turn naming which dinosaur he would like to be) Sung to: "Muffin Man" (Then chant while patting hands on laps) Thump! All through the Mesozoic most small vertebrates were mammals and lizards.[21]. Analysis of their fossils suggests that the animals were indeed small, bipedal predators. For 160 million years, dinosaurs ruled the Earth. [14] Their descendants, the birds, number 9,000 living species, and are the most diverse group of land vertebrates. [4] By the early Jurassic they were the top land vertebrates, and dominated most environments on land. The movie is startling in its impact. 2010. They can be more active, and for longer, than animals who depend on the environment for heating. [2] Fossils of dinosaurs have been found on every continent, and there are still frequent new discoveries. There are also interesting dinosaurs like the Argentinosaurus which is thought to have been the largest dinosaur ever to live and the Dromiceiomimus, which may have been the fastest. The first fossil bird, Archaeopteryx, had a skeleton which looked much like that of a dinosaur. Well-preserved fossils have shown clear evidence of feathers appearing on a number of raptor species. Because of its size, this dinosaur did not have many predators, but the sail could have been used to ward off enemies, as the dinosaur would have appeared to be twice its size with the sail fully extended. The first known dinosaurs were small predators that walked on two legs. These geological events may have reduced sunlight and hindered photosynthesis, leading to a massive disruption in Earth's ecology.[22]. Allen, Vivian; Bates, Karl T; Li, Zhiheng and Hutchinson John R. 2013. The largest dinosaurs were herbivores (plant-eaters), such as Apatosaurus and Brachiosaurus. It is now certain (from fossils discovered in China: see Jehol biota) that small theropods had feathers. The first known dinosaurs were bipedal predators that were one to two metres long.[9][12]. Most of the smaller dinosaurs had feathers, and were probably warm-blooded. It takes a particular kind of paleontologist to come up with a name that's so striking, so descriptive, that it forever fixes a dinosaur in the public imagination, no matter how scant the fossil evidence might be. Adaptive radiation let them live in many ecological niches. [5], From the fossil record, we know that birds are living feathered dinosaurs. Scientists have discovered what they believe to be a new species of theropod dinosaur — making it a close relative of the Tyrannosaurus rex. This is much more efficient than the sprawling legs of a lizard. Plateosaurus engelhardti Although not nearly as large as its leviathan later relatives, such as Apatosaurus and Barosaurus, Plateosaurus, with a body measuring about 25 feet long, was quite large for an early member of the dinosaurian lineage.

The first fossils were recognised as dinosaurs in the early 19th century. Main-stream palaeontologists have followed this view for small theropods, but not for larger herbivores. This would make them active, with a higher metabolism than modern reptiles.
