Are Brachiosaurus fossils rare?
Brachiosaurus is extremely rare,” Dr Wedel wrote. “Brachiosaurus was previously known from only about 10 very incomplete skeletons. Ours makes 11.” And it may also be the oldest, the researchers added, given where the fossils were found.
Where are Brachiosaurus fossils found?
Fossil finds The first Brachiosaurus (B. altithorax) fossil was found in Grand River Valley in western Colorado in 1900. The paleontologist who discovered this partial skeleton, Elmer Riggs, named this new find Brachiosaurus in 1903. Brachiosaurus is one of the rarer sauropods of the Morrison Formation.
What are Brachiosaurus predators?
A healthy, adult Brachiosaurus probably had no predators. The largest-known meat-eaters from that time (the late Jurassic period) and place (North America and Africa) were Allosaurus, Ceratosaurus, and Torvosaurus.
What adaptations did Brachiosaurus have?

- skeleton and vertebrae; they are angled in a way that is does not cause a lot of stress on the body to lift it’s huge, heavy neck to the trees.
- air sacs; they are found along the neck and trunk of Brachiosaurus.
- chisel-like teeth.

Why did the Brachiosaurus go extinct?
A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive. Ash and gas spewing from volcanoes suffocated many of the dinosaurs. Diseases wiped out entire populations of dinosaurs. Food chain imbalances lead to the starvation of the dinosaurs.

What preyed on sauropods?
Fossils reveal that some snakes preyed on baby sauropods. Ancient snakes lurked in dinosaur nesting grounds in order to gobble up hatchlings as they emerged from eggs, fossils from western India suggest.
What did the Brachiosaurus evolve into?
No. Brachiosaurus was a dinosaur that lived around 150 million years ago. By the time that Brachiosaurus became extinct, there were already early mammals called Eutheria living alongside the dinosaurs. The Eutheria gave rise to the placental mammals and then the Artiodactyla and, eventually, the modern giraffe.
Why did Brachiosaurus go extinct?
Where did the Brachiosaurus get its name from?
Brachiosaurus is a genus of sauropod dinosaur from the Jurassic Morrison Formation of North America. It was first described by Elmer S. Riggs in 1903 from fossils found in the Grand River Canyon (now Colorado River) of western Colorado, in the United States. Riggs named the dinosaur Brachiosaurus altithorax,…
How big was the Brachiosaurus and how much did it weigh?
Brachiosaurus is estimated to have been between 18 and 21 meters (59 and 69 ft) long; weight estimates range from 28.3 to 58 metric tons (31.2 and 64 short tons). It had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods.
Are there More Brachiosaurus fossils on Riggs Hill?
More Brachiosaurus fossils are reported on Riggs Hill, but other fossil finds on the hill have been vandalized. During excavation of the specimen, Riggs misidentified the humerus as a deformed femur due to its great length, and this seemed to be confirmed when an equally-sized, well-preserved real femur of the same skeleton was discovered.
What was the Diet of the Brachiosaurus altithorax?
These animals were almost certainly nomadic, slowly migrating in herds to new regions after exhausting the plant resources of a place. The diet of this dinosaur consisted mainly of conifers, cycads and ginkgos. Brachiosaurus was not the only brachiosaurid of the time.
