Why have fossils of brachiosaurus been found on several different continents?

Fossils of BrachiOSaurus have been found on several continents due to the historical phenomenon of continental drift, which is the movement of Earth's continents over millions of years. During the Late Jurassic period, when BrachiOSaurus lived, the continents were positioned differently than they are today, forming a supercontinent called Pangaea. This allowed for the widespread distribution of species, as they could inhabit large areas before the continents separated. Additionally, BrachiOSaurus may have had the ability to migrate across land bridges or through coastal environments, further facilitating their spread.
