The vision of the Scorpius Rex is similar-looking to the future predators' from the ITV series Primeval. While the future predator hunts by sound and the Scorpius by heat, the heartbeat of the prey is still audible.
The kitchen scene appears to be a reference to the original Velociraptor kitchen scene.
Darius stating that the second Scorpius rex's birth is likely possible if its parent have the ability to reproduce asexually by having the DNA of certain frog species in its genome is a callback to a scene where Alan Grant made a similar hypothesis after he and the kids found a raptor nest and eggs at the base of a tree.
The wrecked limo's position against the tree is similar the wrecked Ford Explorer after Alan gets Tim out of its wreckage and they make a mad dash down the tree to avoid it. The scene where Sammy, Brooklynn, Kenji and Yaz only found Darius and Ben's footprints outside the wrecked limo is just like how Ellie Sattler and Robert Muldoon searched the aforementioned wrecked Ford Explorer for Alan and Tim, but only found their footprints instead.
When Darius fired the tranquillizer at the Scorpius rex, the dart is shown flying in slow-motion, which is a reference to the climatic scene from The Lost World: Jurassic Park where Sarah Harding tranquillises the male Buck tyrannosaur.
