Brontosaurus (bront-oh-sore-us) was a genus of large Sauropod that lived in North America during the Late Jurassic.

Characteristics[]

The largest Brontosaurus species could reach about 24.5 meters in length, and have a shoulder height of 8.5 meters. Large Brontosaurus are thought to have had a mass of around 15,000 kg. It had a large, bulky torso, a long neck, and an extremely long tail.

The living creature[]

Fully grown Brontosaurus were comparable in size to their relatives Apatosaurus and Diplodocus. They would have probably been medium-level browsers. Adult Brontosaurus would have presented a formidable challenge to predators like Allosaurus, but juveniles could be taken down with less difficulty.

Importance[]

Brontosaurus is easily the most famous Sauropod dinosaur, featured often in media, especially from the 20th century.

In 1903, the paleontologist Elmer Riggs concluded that Brontosaurus was an invalid genus based on similarities to Apatosaurus. While a 2015 study reached a different conclusion, restoring Brontosaurus as a valid genus, some paleontologists still agree with Riggs' interpretation.
