Dinosaur Brontosaurus had long, thin necks and small heads, adapted for a herbivorous lifestyle; a bulky, heavy torso; and long, whip-like tails. The various species lived during the Late Jurassic epoch in the Morrison Formation of North America, going extinct by the end of the Jurassic. Adult individuals of Brontosaurus are estimated to weigh up to 15 tonnes (15 long tons; 17 short tons) and measure up to 22 meters (72 ft) long. As the archetypal sauropod, Brontosaurus is one of the best-known dinosaurs and has been featured in the film, advertising, and postal stamps, as well as many other types of media. All these Dinosaur Brontosaurus pictures were collected from the internet.
