Troodon is a small bird-like Theropod. It has very long legs with specialized feet, in which the middle long bone was pinched out at the top to form a shock-absorbing wedge. This allowed it to run very fast. Troodon had very large eyes that faced mostly forward, so that it could focus better. It is famous for having one of the largest brains (for its body size) of any dinosaur making it the most intelligent. 

Troodon had a jaw full of many small teeth, but they were not like the teeth of typical meat-eaters. Instead of little serrations running up and down the back of the teeth (as in most meat-eaters), there were larger bumps running along the side, as in many plant-eating dinosaurs and lizards. Some paleontologists speculate that Troodon may have eaten not only small animals, lizards, and baby dinosaurs, but also insects, eggs, and even plants.

Paleontologist Dave Varricchio discovered the first Troodon nest. Like oviraptorosaurs and ground-dwelling birds, Troodon would make a nest on the ground. It would then curl up on top of the nest to brood its eggs.[1]

Wikipedia has a more detailed and comprehensive article on Troodon



Troodon was successfully recreated by Dr. Laura Sorkin inside the Isla Nublar Field Lab.[2] According to Dr. Sorkin the species recreated was Troodon pectinodon[2][3] and was designated IG74726f6f646f6e.[4] Before Troodon was born it was unknown what dinosaur they were until they had hatched.[2]

They were most likely created using Dr. Sorkin's method of not filling in the sequence gaps and instead creating them solely out of 100% extracted DNA.[5] However, despite having been created without add-ins, the cloned Troodon had pronated hands and lacked feathers like all theropods created by InGen though they did have a row of quills or spines running down their back that could be protofeathers. The clones skin was pale gray with irregular dark dorsal stripes and a red underbelly. They would also always be seen roaming in large packs of about 10 individuals.[6]

Their eyes were bulbous and had Tapetum lucidum, a layer of tissue that reflects light through the retina in order to see better in the dark that many animals (such as cats, dogs, and raccoons) have, which made its eyes glow in the dark. As a side effect, they were unable to withstand intense light, such as a simple road flare.[7]

The original Troodon was the smartest dinosaur ever known, being about as smart as an opossum and the clones most likely had this trait, but it is unknown if it was the smartest dinosaur ever recreated by InGen, as the cloned Velociraptor has shown much intelligence by using advanced communication not seen in other dinosaurs and their clones as well as having advanced trapping techniques.[8]

However, Troodon's presence would make any surrounding carnivores flee in fear, even the cloned Velociraptor despite being highly intelligent and being larger than the Troodons.[9] This reputation can be owed to its venomous bite. The toxins in their saliva would cause hallucinations,[10] in some cases causing the victim to become violent and attack nearby individuals.[11] Unless the infection is treated by an extremely powerful tranquilizer, the victim then goes into a series of convulsions and seizures.[10] The final stage is paralysis and brain death.[9] Using this venom as their primary weapon, they would hunt by biting their victim and fleeing, but stalking their victim as it suffers from the effects of the venom.[6]

It is presumed that this venom is naturally secreted like the cloned Dilophosaurus and members of the lizard genus Heloderma, but according to Dr. Gerry Harding's observation of a Troodon wound it looked like "some dinosaurs have been ingesting poisonous plants.”[12] If this is the case, it would imply significant intelligence in Troodon.

When a Troodon was about to lay eggs, she would kill one of her prey as usual, but instead of eating her kill she would instead partially bury it in a secluded area while the victim was still paralyzed and rips her victim open (apparently the abdomen in humans) before proceeding to lay her eggs.[9] It is presumed the victim's body is used to provide both body heat and food for the hatchlings, which would proceed to eat the corpse from the inside out. This method of rearing young is like that of Spider wasp species, with the cloned Troodon being the non-insect that uses this method.[9]

Upon Troodon's creation, Dr. John Hammond, founder of InGen, did not add Troodon to InGen's List because it did not fit his vision for Jurassic Park and wanted them to be evaluated before adding them and considering an attraction for Troodon.[2] Ultimately, Dr. Hammond deemed Troodon a threat to his vision for Jurassic Park and ordered that the clones be destroyed along with the records of their creation. Wanting not to exterminate the dinosaurs she had created, Laura instead lied to Hammond and secretly kept the Troodons on the island in Quarantine Pens[13] to continue studying them.[3]

Isla Nublar Incident (1993)Edit

When Dennis Nedry disabled Jurassic Park's security systems in order to steal dinosaur embryos for Lewis Dodgson,[14] he disabled the Quarantine Pens containing the Troodon pack as well, allowing them to roam freely.[6]


Troodon pectinodon from Jurassic Park: The Game.

The first known action of the freed Troodons was hunting Nima Cruz, a woman who Nedry was supposed to meet with at the handoff for the embryos and went to retrieve the embryo carrier he had when he failed to arrive at the East Dock. The pack scared away the juvenile Dilophosaurus pack that was surrounding her, allowing one of the Troodons to successfully bite Nima. The Troodon pack then proceeded to stalk her as she ran through the jungle suffering from the effects of the venom. However, Nima managed to indirectly evade the pack when she was found by Dr. Gerry Harding and his daughter Jessica Harding after she had stumbled onto the road they were traveling, to which the Hardings took her into their jeep and healed her wound while driving off.

The next day the pack traveled to the Visitor Center, presumably tracking Nima's scent as she had been inside the center earlier. While inside, the pack found Vargas, a member of a mercenary team hired by InGen to rescue any survivors that were still on Isla Nublar, One of the Troodon bit Vargas, leading to him killing the other members of his team while hallucinating. Fellow mercenaries Billy Yoder and Oscar Morales soon arrived after hearing gun shots over their radio. Oscar shot at some of the Troodons though he did not kill any of them and he soon became occupied with the hallucinating Vargas. After the two had a shootout, the Troodon proceeded to eat Vargas who was wounded from the fight with Oscar while he and Billy were looking at the camera footage of the Visitor Center.

Later that day, the pack found and attacked Daniel Cafaro, who was the pilot of the helicopter used by Billy Yoder and Oscar Morales. The Troodon dragged his body to a room inside the Geothermal Power Plant where a female laid eggs inside his chest. Nima, Billy, Dr. Sorkin, and the Hardings discovered his body and the nesting behavior of Troodon just after escaping the Scarred Raptor Leader, who became startled by a nearby Troodon. While in the room, the Troodon pack attacked the humans by crawling through the vents. Their attack failed, however, as Nima Cruz and Yoder prevented them from getting through the vents and Dr. Harding managed to force the gate open to allow his group to escape though Billy was the last to go through the gate as he was busy fending off of the venomous dinosaurs with a shovel.

The pack continued their pursuit of the humans and soon found them again when the group was looking at a map of the tunnels. They were revealed by Billy Yoder using a flare he acquired in the room he had previously encountered the dinosaurs in. Startled by the bright light, the Troodon proceed to run right towards the survivors causing them to separate into two groups, on consisting of Nima Cruz and Dr. Gerry Harding with the other consisting of Billy Yoder, Dr. Laura Sorkin, and Jessica Harding. The pack split up as well to pursue the two groups, but ultimately the two groups managed to escape the Geothermal Power Plant and later regrouped at the Marine Facility.[6]

It is unknown what happened to the Troodon populations on Isla Nublar after the Isla Nublar Incident of 1993, but because John Hammond ordered them to be euthanized they were probably exterminated by the InGen Security Division during either the clean up of Jurassic Park in 1994[15] or during the construction of Masrani Global Corporation's Jurassic World.[16]





John Roxton discovered what he believed to be a Velociraptor skeleton in Mongolia. However, it was actually a Troodon skeleton. The fossil discovered had impressions of its skin.[17]

The Lost World: Jurassic Park SEGA GenesisEdit

Troodon appears in the Sega Genesis The Lost World: Jurassic Park videogame.  This was the Troodon's first appearance in any Jurassic Park video game.  

Jurassic Park III: Park BuilderEdit

Troodon is number. 039 of the Carnivore Ones that can be created in Jurassic Park III: Park Builder.

Jurassic Park: SurvivalEdit

It was planned to appear in the canceled video game Jurassic Park: Survival. It was to have glowing eyes and dwell in caves.[18]

Jurassic Park: BuilderEdit

see Troodon/Builder

Troodon is one of the available dinosaurs on the IOS application, Jurassic Park: Builder. The Troodon uses the same animations of Compsognathus and Velociraptor.

LEGO Jurassic WorldEdit

Troodon is one of the dinosaurs that appear in LEGO Jurassic World. Its physical appearance is based on its appearance in Jurassic Park: The Game, but it does not have the abilities it had in said game, such as venom. Though they have no role in the game's story, they appear as both enemy dinosaurs and they can be unlocked for Free Play by obtaining its Amber Brick in the Isla Sorna "Breeding Facility" level. It is one of the smaller playable dinosaurs in the game, with only the Compsognathus and the Baby Velociraptor being smaller. They have no special abilities though like most dinosaurs in the game they can be customized with certain features from other dinosaurs to grant them certain abilities. Troodon are also encountered on Isla Sorna and Jurassic World, often in groups. Its depiction in LEGO Jurassic World is less sinister (though they are still implied to be dangerous) and their venomous bite is absent.

Jurassic World: The GameEdit

Troodon was added to the game in the September 30th, 2015, but will be released sometime in the future. It will be a limited tournament dinosaur. Unlike in previous games, it will be depicted with feathers, most prominently on its arms.

Behind the scenesEdit

Vargas is the first person in the franchise to be eaten by the Troodon.

Troodon is the first (inherently) nocturnal predator in the Jurassic Park franchise, and one of only three carnivores that use venom as a hunting method - the other two being Dilophosaurus and Procompsognathus. It also the first, and so far only, parasitic dinosaur seen in the Jurassic Park franchise.

The Troodon in Jurassic Park: The Game resemble Deinonycanis, a toy from the Jurassic Park: Chaos Effect toy line that was a hybrid between Deinonychus and Canis dirus a.k.a the Dire wolf.

T. pectinodon is not a real-life species of the animal; rather, it is named after the genus Pectinodon, a very close relative of Troodon, which has been classified as being synonymous with the Troodon species T. ‬formosus and as its own separate Troodon species Troodon bakkeri.

Like many of the animals in the Jurassic Park franchise, the sounds of the Troodon were created by combining the sounds of modern animals. The Troodon's vocalizations appear to have been created by mixing together dolphin clicks, various small bird calls, and the mating call of a bull elk. Its snarls and roars are similar to those of a leopard or a cougar. All of which are combined with the hiss of a crocodile to reflect the reptilian nature of the creature.

In the debut trailer for Jurassic Park: The Game, the unseen Troodon appear to have glowing yellow eyes, whereas in The Game itself, their eyes glow white.

There is a toy model of the Velociraptor from The Lost World: Jurassic World which is identical to Troodon real life appearance.

The Troodon's ability to converge venom by biting its victims, might be based upon the discovery of the Troodon's distant cousin Sinornithosaurus, that was recognized for its unusually long fang-like teeth that had grooves on the surface and discovered for a cavity in the skull, considered to be venom gland, signifying it as the very first poisonous dinosaur. However, further evaluation showed no evidence of it being able to produce venom.


Being a bird-like dinosaur and relatively smart, the Troodon are highly social animals and use their intelligence to communicate oftenly when hunting in a group. They usually talk amongst one another by using a click-like sound, much similar to that of Bat or Dolphin when using echolocation, being nocturnal Troodon aside from their large binocular eyes might have use this form to manoeuvre around in the night by waiting out the vibrations of objects once they used echolocation. The Troodon are very aggressive with most of their sounds being more hostile than any other dinosaur within Jurassic Park; they usually sound off raspy hisses and loud junting screams when snapping at or attacking their prey. Troodon sounds also make a few haunting hisses that large, but somewhat calming that fused alongside their clicks, it more vivid to think that this combination is usually when they leave off to the distance or in a certain area (as shown in the Quarantine Pen).[citation needed]

Telltale Games wanted the Troodon in Jurassic Park: The Game to sound menacing and more exotic than any of the dinosaur heard in the park. Their sound department team gathered a total of four animals for the Troodon's vocals: the raspy hissing of the dinosaur was from a Leopard, the low calm hissing from a Crocodile, the loud junting snaps from a Cougar and when the animal was hurt the screeching bleats from an Elk. The Troodon's clicking sound, which is similar to the sound of the Predator (both of which use similar hunting techniques and have roles as antagonists), were made by the clicking of person using their tongue compressed on to their uvula.[citation needed]
