Dilophosaurus

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 Coelophysis even though Dilophosaurus is currently classified as a member of a different group of theropods rather than Coelophysis and its relatives.

Creation
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 neighboring island of Isla Nublar for InGen's Jurassic Park. They resided in the Dilophosaur Paddock of the park.

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. The frill would expand and rattle when attacking or when preparing to attack. 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 explain the traits above. This could also mean that these traits will disappear when these dinosaurs are older (although this is very unlikely, as the frills and venom spit would remain, but the skull would change). Juveniles would hunt in packs, but only the leader was allowed to disable prey. It is unknown if the adults hunted in packs like the younger individuals. What is more odd is that in the movie, Dilophosaurus had a green color with dark markings, and its frill was a bright yellow with red patterns, but in Jurassic Park: The Game, it was a gray color with red markings, and its frill is gray as well, with a red circular line. It could be possible that the movie version is the male, whereas the game version is a female, thus hinting that the Dilophosaurus are able to breed after all.

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. This is most likely possible, as Dr. Wu noted that Dilophosaurus genetic structure was compatible with the DNA of.

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.

When Dennis Nedry turned off the park's security 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. However, when he turned back around, the "Dilo" was there, and it popped up its frill before spraying venom at Nedry It missed, and Nedry ran to his vehicle. But before he could get in, another shot by the Dilophosaur hit him straight in the eyes. Poor Dennis managed to get in his vehicle, but he lost the counterfeit shaving cream can that held the dinosaur embryos he stole. When he shut the door, he realized with horror the "Dilo" was inside, and it proceeded to devour him. Nima Cruz, one of the agents hired to retrieve Dennis' Barbasol can, later scared off the Dilophosaurus that killed him, 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. Miles agreed, then shoved Nima to the ground and ran for it, hoping that they would attack her. However, the Dilophosauruses attacked Miles despite the circumstances, devouring him while Nima escaped in Nedry's jeep. 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 her 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 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 to continue on foot. A Dilophosaurus pounced on Cruz and the two had a struggle. However, to the dismay of the Dilophosaurus pack, they had to end their pursuit of Cruz because of the arrival of the dangerous Troodon pack. 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 accidentally 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 grasp 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.

Hologram
No Dilophosaurus were known to have been held publicly in Jurassic World, nor were listed on its official website as attractions, but the Innovation Center included it in the Holoscape, along with Velociraptor, Spinosaurus and other dinosaurs created by InGen but not kept on display in the park. The glass of the Gyrosphere is designed to protect visitors even from them, meaning that it could have been in the park at one point.

During the second Isla Nublar incident, the holographic display of Dilophosaurus was briefly used by Gray Mitchell to distract the Velociraptor Delta while he, Claire Dearing, Owen Grady, and his brother Zach Mitchell escaped the building.

Jurassic World: Fallen Kingdom
While not in the trailers so far, it has been revealed that there are surviving Dilophosaurus populations on Isla Nublar, but they and many other creatures will now face an impending danger in the form of an erupting volcanic eruption from Mount Sibo.

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. Their toxin contained 7 different enzymes.

After spitting at a handler, Jurassic Park staff did an investigation on their toxic spit. They also tried to remove the poison sacks, but it proved little success because they could not find them nor did they know where they were placed without doing an autopsy, which park staff wouldn't allow due to the costs of creating new dinosaurs.

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.

End
In the chapter Under Control, it is revealed that three Dilophosaurus have died during the park incident. 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 Dilophosaurs are never seen or mentioned in Jurassic Park's sequel,. 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.

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.

Dilophosaurus is one of the available dinosaurs on the IOS application, Jurassic Park: Builder. It should be noted that, when it is young, it sounds like a raptor, and when adult, its sound is that of a T. rex.

LEGO Jurassic World
Dilophosaurus appears in the video game LEGO Jurassic World. It is one of the 20 playable dinosaurs in the game and is among the first carnivorous dinosaurs that can be unlocked for Free Play, as its Amber Brick is the earliest one that can be obtained in the Jurassic Park section that contains the DNA of a carnivorous Dinosaur. Its special ability is being able to spit its iconic venom, making them only dinosaur in the game that can naturally use ranged attacks, though dinosaurs can be customized with a Dilophosaurus head to grant them this ability. Their acidic spit can also be used to destroy Black colored Lego bricks. Due to their size, the Dilophosaurus can be accessed through the character selection in Free Play once their Amber Brick is obtained, as well as via Dino Spawners. The species Amber Brick can be obtained during the Jurassic Park T. Rex Chase level and its skeleton can be unlocked by collecting all 10 Minikits in the Park Shutdown chapter (T. Rex Enclosure, Rescue Timmy, and T. Rex Chase). Dilophosaurus also appear as regular enemies, with some of them being smaller than the playable ones. Several Dilophosaurus can also be encountered in the Dilophosaur Paddock and will only attack if attack be the player. A park employee inside of their pin will mention getting spit on by them and humorously reveals that it was sticky and his feet got stuck together and had to jump around the entire day. Another employee will mention that he doesn't want to get spit on, as the laundry on the island is expensive. These comments indicate that in the universe of LEGO Jurassic World their spit is not poisonous, though it is acidic enough to break down Black LEGO objects. Like the film, the Dilophosaurus spits at Nedry and follows him into the car though it doesn't eat him as Nedry manages to stuff one of his chicken legs in the Dilophosaur's mouth and flees from the vehicle, though he leaves the Barbasol can in the vehicle which is knocked out as the Dilophosaurus struggles with the chicken leg in its mouth. Later on, when Lex is rebooting the park's systems, Nedry can be seen trying to avoid the Dilophosaur that is searching for him. Interestingly, in Free Mode, the Dilophosaurus Acid Spit is required to remove a Black Lego rock covering dirt where the Barbasol can is buried allowing it to be dug up and reassembled to receive a Gold Brick. In the same area, a photo of Nedry and the Dilophosaur can be taken to receive a Gold Brick as well.

Jurassic Park: The Ride
In Jurassic Park: The Ride, a number of Dilophosaurs can be seen. The first one that appears in the ride feasting on the dead remains of passengers of a boat that had gone into despair in the Raptor Containment Area. A group of Dilophosaurus (two in the Hollywood version, three in the Universal Studios Orlando version) spit at the visitors as they go into the Water Treatment Facility.

In the Halloween event, Project Evilution, a scientist named Dr. Burton accidentally creates human-Dilophosaurus hybrids. When visitors encounter them, the hybrids want to eat them. At the end of the Project Evilution ride, they hang their creator.

Behind the scenes
Dilophosaurus, along with Procompsognathus and Troodon, are the only known venomous dinosaurs in the Jurassic Park franchise.

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.

The movie's Dilo was also sized down to prevent confusion with the raptors. Because of its minor role, the filmmakers were able to not fully follow the storyboards involving the Dilo completely. Similarly, Shane Mahan—head of the Stan Winston Studio team who created the Dilophosaur—went ahead and created the full-sized animatronic without making a full-size maquette, his reasons being that he was confident that his team did not require a full maquette to create it and because he "wanted to get right into the actual character." The Stan Winston Studio team responsible for the creation of the Dilophosaur animatronic analyzed frame by frame a documentary featuring an ostrich which the used to create the hopping gait of its animatronic. Initially, a cam operated mechanism was created for one of its legs to follow the gait of an ostrich before a different mechanism was chosen. This later mechanism were rods coming out of its feet going beneath the floor and operated by a puppeteer. Inspired by the Steadicam, Rick Galinson created the concept for its neck. Each spring in the neck and head were sprung differently with each spring being heavier from the head the to the body, providing realistic movements. This had mechanism had originally been proposed for the raptor, but Stan Winston Studio was not convinced that it work had an animal that large, so the steady cam mechanism was transferred to the Dilophosaurus. After the mechanism was crated, Stan Winston was impressed by what Galinson had done and applied it to the animatronic of the Velociraptor's head and neck, scrapping an alternate design for the raptor animatronic. The animatronic had three interchangeable heads: the frill in a lowered position, mechanized to allow the frill to open, and lastly the frill open and able to rattle as well as the ability to spit. The frill itself was a sheet of latex rubber glued onto some support rods hooked to a pulley. When activated it rotate out and forward at the same time as it was coming off the animatronic Dilo's neck. Its ability to spit was a paintball mechanism with the spit itself being a mixture of KY Jelly and food coloring. Underneath the tongue of the third head were two holes for the tubing that would have high-pressure air pumped through them to allow the animatronic the ability to "spit". The rest of the body, such as the head, tail, and arms were radio controlled. Cable-actuated insert legs were also created to portray the Dilo's hop when it initially approaches Nedry. The hopping was created by the legs being suspended from stage catwalks on bungee cords. For the filming of Nedry's demise, a trench was built on the set for the path the Dilophosaurus would take as well as so that Shane Mahan could support and puppeteer the Dilo's legs while a crane above supported its body and the rest of the team responsible for its creation radio-controlled the other body parts of the animatronic upstairs. Because of the copious amount of water that was to be on the set during shooting, the soundstage used in the filming of the scene had a water tank underneath the set and was supposed to drain into the, but the drainage system did not function well. This caused water to overflow into the puppeteering area, which lead to Mahan being given a riser to stand on just to get at least some of the water off of him, but the water level only got higher. The roaring of the water made it difficult to hear out of his headset making him unable to hear the film crew, which made him rely on video monitor stacked onto some boxes. But water got so high that this monitor floated away from Mahan and was rising to his chest. However, this was toward the end of filming and filming of the scene was filmed without Mahan drowning. Director Steven Spielberg thought that the Dilophosaurus was going to be the easiest practical dinosaur to film in Jurassic Park, but was disappointed by the problems that occurred when filming of the scene. The Dilophosaurus and Triceratops are the only dinosaurs to appear in that did not use CGI, only using animatronics.

The sounds of the Dilophosaurus came from various sources. The hooting sounds it made were created from a call while the screeches it made when preparing to spit were created from a mixture of a hawk, howler monkey, an  (that has a raspy call), and sound designer Gary Rydstrom making a croaking sound to give the dinosaur some body and weight. The rattling of its frill was also created from a rattlesnake and a "very exotic" insect.

The Jurassic Park trading card of Dilophosaurus incorrectly states that it is forty feet in height. If this were the case that would mean the crested dinosaur would be taller than Spinosaurus and Tyrannosaurus as well as both its real life and film counterparts. This seems to have been an error by the publisher as the card "A Dilophosaur Drops By" gives a more accurate height of four feet for the film's Dilo.

The Jurassic Park depiction of Dilophosaurus has been taken up by others. Several other video games, such as ', ', , 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  sketch "Dinosaur Rap" (a music video for Trevor Moore's "Gettin' High With Dinosaurs") features a Dilophosaurus, complete with a short frill.

The holographic Dilophosaurus in was the size of Delta the Velociraptor, providing more evidence that the Dilophosaurus in Jurassic Park was a juvenile.
