Spinosaurus (Jurassic Park 3)

Spinosaurus is the main antagonist in the 2001 film, Jurassic Park III.

Background
Spinosaurus was successfully recreated by InGen in the lab on Isla Sorna. Oddly, it was not a dinosaur on InGen's List nor was it planned to be an attraction in Jurassic Park. How he ended up came to being but not on the list was due to either the DNA to create him mistaken as Baryonyx's or Suchmimus', or rather the mistake was realized by the scientist whom create him during the cloning process, but had no chance to do something about it due to Hurricane Clarissa occurred around this time allowing any surviving Spinosaurs to roam freely without being documented.

Isla Sorna Incident (2001)
It first makes an appearance when the plane lands on Isla Sorna. Nash and Udesky quickly leaves Cooper behind, then begs the plane to stop. The Spinosaurus runs out of the forest, grabbing Cooper in his mouth & killing him. After the plane crashes into the forest, the spino rips the front of the plane off & drags Nash out by his legs, then drops him onto the forest floor. Nash then tries to crawl away but the spino pins him down & kills him, the others manage to escape. They then encounter a young Tyrannosaurus and run back towards the Spinosaurus. A quick vicious and brutal battle ensues and the Spinosaurus comes out victorious by breaking the T-Rex's neck with its jaws and the others escape again. Later the Spinosaurus makes another appearance when Eric & Dr. Grant are at the fence after they meet up with Eric's parents. They hear the phone that the spino ate after eating Nash. They turn around seeing the spino; they run making it through a opening in the fence but the Spinosaurus breaks down the fence and the group flees in a abandoned laboratory. The last appearance it makes is when everyone is on the boat. It comes out of the water and attacking the boat. It almost kill Paul Kirby but Dr. Grant scares it away with a flare gun. It is unknown what happened to him after this.

LEGO Jurassic World
In LEGO Jurassic World, his role was more or less same, but more comedic:
 * When chasing Cooper, instead of devouring him, he tossed Nash aside right on to the he plane's windshield, where he is wiped out of the way before the plane crashed.
 * When tries to devour Nash, Nash unexpectedly stuck Kirby's satellite phone on his mouth before runs off to the jungle, briefly distract him.
 * The Spinosaurus ends up getting caught in a tree just like in the film, though the branches of which close on it shuts like stockades. Billy even tosses apples at the Spino for fun. Later on, the dinosaur manages to free itself from the tree.
 * The infamous fight between  Spinosaurus and the T. rex remains unresolved, most likely resulting in a draw.
 * Spinosaurus did not attack Paul, Amanda and Billy after they were reunited with Eric and Alan. Instead, it was found sleeping on a dnio-sized hammock while the main group sneaked away from him. However, a similar scene occurs in the opening cutscene for the aviary level.
 * Unlike in the movie, the Spinosaurus never flees permanently after being scared away by the fire caused by the group but instead jumps into the crane. Here, it makes an appearance near the end alongside the Velociraptors to attempt to return the phone to the main group and asked to tag along for the mainland due to hearing hotel ads from the said phone, who immediately become scared and run into the rescue helicopters immediately.
