Brontosaurus is a sauropod dinosaur from the Jurassic period of North America. It was originally a different genus from Apatosaurus, but the type species Brontosaurus excelsus was reclassified as a species of Apatosaurus called Apatosaurus excelsus, meaning Brontosaurus was considered scientifically invalid for over 110 years. However, an extensive study published in 2015 by a joint research team of United Kingdom and Portugal concluded that Brontosaurus was a valid genus of sauropod distinct from Apatosaurus, resurrecting the genus.
Though no living animals of this species make an appearance in the film, Brontosaurus is mentioned on a sign depicting the map of Gyrosphere Valley.
Behind the scenes
- Scriptwriter David Koepp confused Brachiosaurus for Brontosaurus in scene 15 of the Jurassic Park script.
- Much like Tim, fans have confused Brachiosaurus in the first film for Brontosaurus.
