Brontosaurus is actually an invalid name for Apatosaurus excelsus. Apatosaurus existed from 154 to 150 million years ago, which was during the Kimmeridgian and Tithonian stages of the Jurassic period of the Mesozoic era.
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.
Late Jurassic.
