Brontosaurus wasn't an actual species. This was an error on the part of paleontologists at the time, who reconstructed this supposed species using the bones of more than one species. So, to answer you question, the brontosaurus didn't ever live.
Apatosaurus, once known as Brontosaurus.
It live on Late Jurassic Period, 154-150Ma.

Brontosaurus is an invalid name for Apatosaurus excelsus, which lived in North America. Thus, it lived in the Western Hemisphere and in the Northern Hemisphere.
A brain explosion!
the Utes live in Colorado. They also live in Utah, and when settlers kicked them out, they named it Utah after the Utes
It didn't. The brontosaurus never existed; it was put together from faulty data. (The closest real-life prehistoric animal was the Apatosaurus, which lived about 150 million years ago.)
Brontosaurus was an herbavore therefor it does not hunt. However Brontosaurus does move and graze in herds.
All known Apatosaurus fossils have been found in the Morrison Formation of the western USA. Fossils are known from Colorado, Wyoming, Oklahoma, and Utah.
