Brontosaurus belongs to the sauropod genus of dinosaurs, which lived in North America during the Late Jurassic period, about 150 million years ago. This dinosaur’s fossils were found in Western North America in 1874. The specimen is still displayed on display in the Great Hall of Yale’s Peabody Museum of Natural History. This specimen is a large, long-necked, quadrupedal animal with a long tail and short forelimbs, slightly shorter than the hindlimbs. Brontosaurus had a tall spine on its vertebrae, like its close relative, Apatosaurus. Brontosaurus is a well-known dinosaur to be featured in films, postage stamps, advertising, and many other media types.
