The spitting frilled lizard was cut from Jurassic Park IV (later renamed Jurassic World). The following information is non-canon
Chlamydosaurus Sputori (name meaning “Spitting Frilled Lizard”) was a species planned to appear in the cut Jurassic Park IV. These "spitters' are large, probably up to three metres long[1]. The ones at Jurassic Park were large, and took on prey such as unlucky humans. For Jurassic Park IV, they would've been used instead of Dilophosaurus. In the abandoned script, they were first seen in a flashback, where one kills Nedry, instead of a Dilophosaurus. Later, two called Casper and Pollux are seen being trained by Nick, alongside the genetically engineered Deinonychus. In the end of the abandoned script, they escape, killing a man called Pepe. They attempt to attack Nick, but run off into the jungle.
