In 1999, shortly after the acquisition of InGen by Masrani Global Corporation in 1998 and after the passing of the Gene Guard Act in 1997, the Spinosaurus, along with the three other aforementioned dinosaurs were recreated by unnamed InGen scientists inside the corporation's compound. The Spinosaurus was one of the four illegally cloned dinosaurs that were either not on InGen's list or were not planned to be an attraction in Isla Nublar's Jurassic Park, alongside Ceratosaurus, Corythosaurus, and Ankylosaurus.
