Imagine finding fossils of an undiscovered sauropod while adventuring with some friends. Well that is what happened to Elmer S. Riggs. He discovered the first fossils of the Brachiosaurus. In 1900, Riggs found a partial skeleton of a Brachiosaurus in the rocks of the Brushy Basin Membrane of the Morrison Formation. The fossils were studied and information on this species was revealed.
Brachiosaurs lived in the late Jurassic period, which was about 145 to 156 million years ago. The Jurassic period was warm with tropical breezes which affected the variety of plants. During the late Jurassic period, Pangea broke into two supercontinents, Laurasia and Gondwana. Brachiosaurs lived in present-day North America, although fossils were found in Portugal
