Why did Brachiosaurus go extinct?
According to the most popular theory, the Brachiosaurus dinosaur became extinct during the end of the Cretaceous period due to the impact of a meteor on Earth’s surface. … Those that could not survive the cold, such as dinosaurs, may have died as a result.

The main difference between Brachiosaurus and Brontosaurus is that the Brachiosaurus is a genus of dinosaur and Brontosaurus is a genus of reptiles (fossil). Brachiosaurus is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154–153 million years ago.
How long is a Brachiosaurus neck?
For Brachiosaurus, with its approximately 30-foot (9-meter) long neck, low browsing reduces the overall cost of foraging by 80 percent, compared with dinosaurs with shorter necks, according to their study in the journal Biology Letters.
Why are dinosaurs no longer living?
The dust blocked sunlight, making the planet very cold and dark. Then, over time, the gases trapped heat, causing the Earth to get even hotter than it was before the asteroid hit. This change was deadly for most dinosaurs, and they became extinct.
Are dinosaurs still alive?
Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Is the Brachiosaurus fake?
Well fear not, because Brachiosaurus is still a valid dinosaur, and there’s a good reason as to why the animal you think is Brachiosaurus actually isn’t. Brachiosaurus was named in 1903 by Elmer Riggs of Chicago’s Field Museum (Riggs, 1903).
