Jurassic World was trying to bring back the Spinosaurus from Jurassic Park 3 shortly before the park was destroyed. Reviving and rebranding the Jurassic Park franchise with Jurassic World was a smart decision by Universal Pictures and it's led to a resurgence in interest in Michael Crichton's world. Part of that meant de-canonizing The Lost World: Jurassic Park and Jurassic Park 3; however, events from both films have slowly started to trickle back into continuity through supplemental material.

One of the things that seems to have been made canon again is the existence of the Spinosaurus. In Jurassic Park 3, Dr. Grant is deceived into landing on Isla Sorna - InGen's Site B, a second island that was used to breed dinosaurs before transferring them to the main island, Isla Nublar - where he and others came into contact with the Spinosaurus. According to Jurassic World: Fallen Kingdom's viral website, Dinosaur Protection Group, InGen illegally cloned dinosaurs - presumably including the Spinosaurus - and released them on Isla Sorna in 1999, which noticeably disrupted the ecosystem.

The Spinosaurus, though a real dinosaur, was the franchise's attempt at creating a theme-park monster, just like Dr. Grant had accused John Hammond of doing with Jurassic Park. It's unclear what happened to the Spinosaurus from Jurassic Park 3, but a skeleton of the dinosaur was on display in the movie Jurassic World. And while it was unknown if Jurassic World recreated the Spinosaurus, the animated series Camp Cretaceous confirms that Dr. Wu was trying to revive it before the park was destroyed. He might've been successful and viewers just don't know yet.

In Jurassic World: Camp Cretaceous season 1, episode 2, "Secrets", some of the group members visit one of Jurassic World's satellite genetics labs. While there, Brooklynn takes the opportunity to sneak into Dr. Wu's private office, where she discovers his file on the Indominus rex. However, before she tries to break into Dr. Wu's confidential folder, she sees information about the Spinosaurus on his screen, thus implying that Dr. Wu and Jurassic World were looking into bringing back the dinosaur.

Given that the Spinosaurus information was found alongside Dr. Wu's files on the Indominus rex, perhaps the park considered the Jurassic Park 3 dinosaur to be a monster-like animal too. It certainly had that quality in the 2001 movie, defeating the Tyrannosaurus rex and killing several other dinosaurs along the way. Perhaps its brief tease in Camp Cretaceous is setting up its return in Jurassic World: Dominion in 2021. If the Spinosaurus on Isla Sorna survived and was eventually transported back to the United States along with the rest of the dinosaurs, there's a chance it could reappear at some point in the third and final film in the trilogy.
