What kind of dinosaur is Brachiosaurus?
Brachiosaurus ( / ˌbrækiəˈsɔːrəs /) is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154–153 million years ago. It was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado, United States.
What is the ontogeny of Brachiosaurus?
The ontogeny of Brachiosaurus has been reconstructed by Carballido and colleagues in 2012 based on Toni (SMA 0009), a postcranial skeleton of a young juvenile with an estimated total body length of just 2 meters (6.6 ft). This skeleton shares some unique traits with the B. altithorax holotype, indicating it is referable to this species.
Can You mount a Brachiosaurus?
No mount of Brachiosaurus was attempted because only 20% of the skeleton had been recovered. In 1993, the holotype bones were molded and cast, and the missing bones were sculpted based on material of the related Brachiosaurus brancai (now Giraffatitan) in Museum für Naturkunde, Berlin.
What was the maturation rate of Brachiosaurus?
The maturation rate differed between species. Its bone structure indicates that Brachiosaurus was able to reproduce when it reached 40% of its maximal size. Brachiosaurus is known only from the Morrison Formation of western North America (following the reassignment of the African species).
Hur lång är Brachiosaurus hals?
