Dilophosaurus was one of the largest carnivorous dinosaurs of the Early Jurassic Period. Dilophosaurus gets its name from the two thin crests of bone on the top of its head. These were probably used as a display for courtship purposes (it's unlikely that it had a frill like the movie suggests). Dilophosaurus has been found in both the U.S. and China, which, although part of the same huge landmass, were still quite a long distance from each other.

As a more primitive predatory dinosaur, Dilophosaurus didn't have forward facing eyes to give it stereo vision. It may have used scent as an integral part of its hunting technique. It had long and slender, rear-curving teeth in long jaws and strong front arms which would have been effective in grabbing prey. It was fast - probably with a top speed of about 30-mph. It also had a long tail that could have been used as a whip in a fight. Footprints attributed to Dilophosaurus appear in groups, so it may have hunted in small packs. It shares the same overall body configuration as its ancestor Coelophysis.[4]

Wikipedia has a more detailed and comprehensive article on Dilophosaurus




The Dilophosaurus bio with its adult size.

Dilophosaurus was recreated by InGen in their compound on Isla Sorna where they raised by the workers there until a few months had passed where they would be transported to the neighbouring island Isla Nublar for InGen's Jurassic Park. They resided in the Dilophosaur Paddock.

The cloned Dilophosaurus had very abnormal traits that the original never had. These traits include a frill, venom glands, and a skull that resembled dromaeosaurids like Deinonychus and InGen's recreation of Velociraptor. The Dilophosaurus clones could spit venom at a range of 6 meters (20 feet) and would aim for their prey's face to stun it before the Dilophosaurus would come in for the kill. They also were smaller than their original counterpart, though it was said that this was because the ones that were on Isla Nublar were juveniles, which could also explain the traits above. Juveniles would hunt in packs, but only the leader was allowed to disable prey.[5] It is unknown if the adults hunted in packs like the younger individuals.

Dr. Laura Sorkin believed it was Dr. Henry Wu's inclusion of frog DNA or a splicing error that was responsible for the abnormal traits seen in the cloned Dilophosaurs, or at least the juveniles.[6]

Isla Nublar Incident (1993)

The endorsement team was meant to see the Dilophosaurus in its paddock during their tour of Jurassic Park, but no Dilophosaurs revealed themselves to the visitors.

JP1 DilophosaurusHides

The Dilophosaurus hiding behind a tree.

When Dennis Nedry turned off the park's secuirty systems so he could steal InGen's dinosaur embryos, Dilophosaurus was one of the many dinosaurs that were free to roam the island. One such Dilophosaur stalked Nedry himself when he was trying to get his vehicle unstuck out of a fallen tree limb. Feeling uneasy, Nedry stopped rope towing his jeep to face his stalker that was right behind him. Dennis Nedry tried to trick the dangerous dinosaur into fetching a stick for him, but the Dilophosaurus showed little care for the stick outside of the brief sound it made when it hit the forest floor. Angered that his trick was unsuccessful, Dennis Nedry jeered the Dilophosaur before running back to his jeep. But when he was climbing up the hill to get to his vehicle, the Dilophosaurus followed in pursuit and began to spit its venom at Nedry. The Dilophosaur's first attack failed to reach his eyes and its prey increased the pace of his escape only for its next spit managed to hit its target. While Dennis Nedry was wiping the stinging venom from his, the Dilophosaurus went inside his vehicle where it proceeded to kill him once he got into the driver's seat. Nima Cruz, one of the agents hired to retrieve Dennis' Barbasol can, later scared the Dilophosaurus that killed him off while it was eating his corpse.

After she and her colleague Miles Chadwick retrieved the Barbasol can that had gotten lost when Dennis Nedry was disoriented from the venom on his face, another Dilophosaurus attacked Miles Chadwick. Reacting to the toxin sprayed in his eyes, Miles pulled out his handgun and began to fire at the dinosaur, successfully scaring it off. But it soon returned with its pack to finish what it had started. Once Nima repaired the jeep, they initiated their attack. The two humans attempted to flee but were cornered by the Dilophosaurus not long after their decision. Miles started firing his pistol before Nima told him not to, saying that he didn't to waste his bullets because there were too many Dilophosaurs. Instead, she suggested that they should try to distract the Dilophosaurus pack. Chadwick responded selfishly by pushing Nima Cruz right at the Dilophosaurs, thinking that they would go after her instead of him. However, two of the dinosaurs wanted Miles Chadwick over Nima and they proceeded to devour him allowing Cruz a chance to drive off in Nedry's jeep that she had repaired just before the pack's ambush.

Dilophasaurus 3

A Dilophosaurus preparing to attack Nima.

One pursued her while she was running to the staff vehicle and attempted to pounce on her, but was pushed aside by Nima when it did so. Once she had reached the vehicle, Nima dodged toxic spit from another Dilophosaurus that had encountered Nima Cruz at the start of the offensive that was on top of the jeep and then another Dilophosaur ran straight at Cruz only to receive a car door to the face. A Dilophosaur that behind the individual was hit by the car door proceeded to spit at Nima while she was inside the automobile, but she shielded herself from the venom by slamming the jeep's door. The rest of the pack began surround the vehicle with one jumping onto the jeep's hood trying to shatter the windshield even after Nima cranked the vehicle and was driving away. This Dilophosaurus was later flung off by the movements of the jeep and was hit by afterward.

The pack finally got another chance at killing Nima Cruz when she crashed her recently acquired vehicle on a tree after her brief problem with the Dilophosaurus on her vehicle's roof leaving her on foot. A Dilophosaurus pounced on Nima Cruz and the two had a struggle. However, to the dismay of the Dilophosaurus pack, they had to end their pursuit of Nima Cruz because of the arrival of the dangerous Troodon pack.

B Yoder

A Dilophosaurus attacking Billy Yoder.

The next day, Billy Yoder, a mercenary hired by InGen to rescue any survivors of the Isla Nublar Incident of 1993, had a skirmish with a Dilophosaurus while he was exploring one of Isla Nublar's jungles with fellow mercenary Oscar Morales. The two heard the Dilophosaurus upon entering the jungle, but it didn't choose to strike Billy Yoder until he had accidently stepped on an egg that was inside a nearby nest (which could have belonged to the attacking dinosaur). Billy dodged the Dilophosaur's projectile attack right before it pounced on him, which in turn caused him to lose his assault rifle. Billy broke free of the Dilophosaur's and dodged multiple attacks from it, but at the end of the fight the Dilophosaur pinned him to the ground again after he went to retrieve his rifle. Though before the conflict could continue further, Oscar Morales intervened by kicking the Dilophosaur off of Yoder very hard. Oscar wanted to kill the dinosaur, but Billy told him not to, saying that wasn't much of a threat now after it was hurt. The Dilo then ran off while Billy Yoder was stating his reasons not to kill it.

It is unknown if there were any surviving populations after the Isla Nublar Incident of 1993. It might have become wild on Isla Sorna after Hurricane Clarissa struck the island because Dilophosaurus was among one of the information sheets given to the InGen Hunters during the Isla Sorna Incident of 1997 and was also a screensaver for one of the computers inside the Fleetwood RV Mobile Lab that was also used in the same incident.

Production and development

The Dilophosaurus is the only dinosaur to appear in Jurassic Park that did not use CGI, only using animatronics.

The Jurassic Park depiction of Dilophosaurus has been taken up by others. Several other video games, such as ParaWorld, Jurassic: The Hunted, Nanosaur, Ice Age: Dawn of the Dinosaurs, feature Dilophosaurus modeled after the representations in Jurassic Park. In Primal Carnage the dilophosaur can spit poison over long distances, but it doesn't have a frill.

The Whitest Kids U'Know sketch "Dinosaur Rap" (a music video for Trevor Moore's "Gettin' High With Dinosaurs") features a Dilophosaurus, complete with a short frill.

Nedry's Plan Goes Awry Scene - Jurassic Park Movie (1993) - HD


  • Dilophosaurus, along with Procompsognathus and Troodon, are the only known venomous dinosaurs in the Jurassic Park franchise.
  • Dilophosaurus is one of the dinosaurs listed in the Holoscape inside the Innovation Center of Jurassic World. It is unknown if Dilophosaurus is one of the dinosaurs living in the park.
  • Dilophosaurus lived during the early Jurassic Period, before mosquitoes are currently confirmed by the fossil record to exist. If Jurassic Park was able to find any viable DNA specimens, there would have been very little to go on. This would mean that there would be more gaps than normal in the DNA sequence, subsequently filled by more frog DNA. This could explain why the Dilophosaurus are so different from their prehistoric counterparts, far more so than other dinosaurs.

Jurassic Park

The Dilophosaurus is first seen during the Park Drive near the river. They see one animal, drinking from the river. It is a 10 foot tall carnivore, with a heavy tail, strong hind limbs, and a long neck. Its crests make a V shape above the animal's head. The crests are red and have black stripes, like a parrot or toucan, with one sex (maybe male) having darker crests than the other.. Its body is covered with yellow and black spots, like a leopard, with a light green belly. It has a hooting that sounds like an owl. The Dilophosaurus clones are able to spit venom at a range of 15 meters (50 feet). Also, one gender was smaller than the other.[7][8][9][10]

Nedry's death

In the chapter "Nedry", Dennis Nedry is on his way to smuggle Dinosaur embryos out of the Park. He has taken a wrong turn and instead of the sea he has reached the river (near the Dilophosaurus territory). When Nedry tries to get back to his car he hears a hooting noise. Then he is confronted by the large and dangerous Dilophosaurus. Dennis is first blinded, then his gut is ripped open, and finally the creature puts his jaws around his head.

Nedry's body is later found by Muldoon and Gennaro, with Muldoon remarking "They blinded him, then ripped him down the middle. Not a nice way to go. Maybe there's justice in this world after all."

River Adventure

Because no frog DNA was used to clone the dilophosaurs they don't reproduce in the first novel. However, in the first novel Grant sees a couple of Dilophosaurus (both male and female) at the river, which were performing a mating ritual. This seeming contradiction is never explained.


In the chapter Under Control, it is revealed that three Dilophosaurus have died during the park incident.[11] They might have been hunted and killed by the Raptors or the Tyrannosaurus after they escaped. All the Dilophosaurus are killed during the Costa Rica Napalm Bombing.

The Lost World

The Dilophosaurs are never seen or mentioned in Jurassic Park's sequel, The Lost World. However, they might have died out due to their lack to reproduce, or just nesting in a different region of Isla Sorna.

All of the games used the juvenile Dilophosaurus seen in the first film to depict adult dilophosaurs.

The video shows that the animal is 7 meters (23 ft) long, as it was in reality, but it still has the neck frill.

Jurassic Park: Operation Genesis

see Dilophosaurus/Operation Genesis

Dilophosaurs appear Jurassic Park: Operation Genesis as a two-star small carnivore, the game's dilophosaur shares all of the characteristics of the one in the movie, from the frill to the small stature.

It can spit venom at prey but does not, however, spit venom at the visitors, despite the spaces between the bars on the fence. If not in the fence though, they then can hunt visitors, as well as cleaners, even though the cleaners will most likely never be killed by the dinosaurs, no matter how many times they've been hit by venom. This is most likely a game play error, or the cleaners are wearing venom proof clothing.

The Dilophosaurus (the weakest of the small carnivores) will only attack and kill small herbivores such as Dryosaurus, Homalocephale, and Gallimimus and is unable to take down large or armored small herbivores. They can be placed along with Velociraptor in one enclosure as long as they are not rampaging. They can even be placed with non aggressive herbivores such as Edmontosaurus.

Jurassic Park: Builder

see Dilophosaurus/Builder

Dilophosaurus is one of the available dinosaurs on the IOS application, Jurassic Park: Builder. It should be noted in Builder that, when tapped, the Dilo exposes its frill and roars. When it is young, it sounds like a raptor, and when adult, its sound is that of a T. rex. In the Battle Arena the Dilo looks similar in size to the Velociraptor, suggesting that the one from the movie is not fully grown.

LEGO Jurassic World

Dilophosaurus will appear in the video game LEGO Jurassic World. It is one of the 20 playable dinosaurs in the game. It's special ability is being to spit its iconic venom.[12]
