Dilophosaurus

Dilophosaurus is a carnivorous dinosaur in Jurassic Park. It may seem a little playful, but when it gets it prey targeted it releases its frill and sprays out its venomous spit to parlyze it's prey "eating at its lesuire." A Dilophosaurus was spotted when Dennis Nedry got lost and fell down a cliff then ran into the Dilophosaurus.
