The Dinosauria Dinosaurs, one of the most successful groups of animals (in terms of longevity) that have ever lived, evolved into many diverse sizes and shapes, with many equally diverse modes of living. The term "Dinosauria" was invented by Sir Richard Owen in 1842 to describe these "fearfully great reptiles," specifically Megalosaurus, Iguanodon, and Hylaeosaurus, the only three dinosaurs known at the time. The creatures that we normally think of as dinosaurs lived during the Mesozoic Era, from late in the Triassic period (about 225 million years ago) until the end of the Cretaceous (about 65 million years ago). But we now know that they actually live on today as the birds. Some things to keep in mind about dinosaurs: • Not everything big and dead is a dinosaur. • Not all dinosaurs lived at the same time. • Dinosaurs are not extinct. Find answers to some commonly asked questions about dinosaurs: • Are birds really dinosaurs? Visit these special exhibits on some popular dinosaurs: Weishampel, D.B., P.

It was founded in 1945 at the signing of the United Nations Charter by 51 countries, replacing the League of Nations founded in 1919. The UN was founded after the end of World War II by the victorious allied powers with the hope that it would act to prevent and intervene in conflicts between nations and make future wars impossible or limited. The organization's structure still reflects in some ways the circumstances of its founding, which has led to calls for reform.
