There is no conclusive evidence that any dinosaur possessed poisonous saliva. The poison-spitting dinosaur reconstructed in Jurassic Park is Dilophosaurus. At the time the movie was produced, there was no evidence that this or any other dinosaur spat poison or had poisonous saliva of any kind.

About Dilo

+ It was slender and lightly built, and the skull was proportionally large, but delicate.

+ The snout was narrow, and the upper jaw had a gap or kink below the nostril.

+ It had a pair of longitudinal, plate-shaped crests on its skull, similar to a cassowary with two crests.

+ The mandible was slender and delicate at the front, but deep at the back. The teeth were long, curved, thin, and compressed sideways. Those in the lower jaw were much smaller than those of the upper jaw.

+ Most of the teeth had serrations at their front and back edges.

+ The neck was long, and its vertebrae were hollow, and very light.

+ The arms were powerful, with a long and slender upper arm bone. The hands had four fingers: the first was short but strong and bore a large claw, the two following fingers were longer and slenderer with smaller claws, and the fourth was vestigial. The thigh bone was massive, the feet were stout, and the toes bore large claws.
