At least four Apatosaurus were successfully transported to the mainland. In 2015, several Apatosaurus were brutally killed by the rampaging Indominus rex, though surviving members of the population were later encountered on Nublar four years later, during the volcanic eruption of Mount Sibo.
Apatosaurus was eventually cloned and exhibited on the island, where it lived alongside numerous other species of herbivore such as Triceratops, Stegosaurus, and Parasaurolophus.
However, after the disastrous San Diego Incident, InGen was acquired by Masrani Global, which began development of Jurassic World on Nublar. Apatosaurus was originally planned to be exhibited as an attraction for the original Jurassic Park on Isla Nublar, with 57% of the genome completed by InGen by 1993.
