The Diplodocus Dinosaurs
MOSI is one of a handful of museums in the world to display one of the largest articulated dinosaurs ever discovered. Sauropods were the colossus of their age, some tipping the scales at a full forty tons. Despite their massive size, they had only a tiny brain - the smallest brain in relation to its bulk of any vertebrate. They were plant eaters and their long necks enabled them to pick food from high in the trees where others couldn't reach. Their long tails helped to balance their very long necks, making it possible for some to reach as high as five stories. The sauropods that occupy MOSI's lobby reach three stories with a total combined length of approximately 150 feet.
