"Compsognathus triassicus. Found by Fraas in Bavaria in 1913."
Robert Burke.(src)

Compsognathus is an extinct genus compsognathid theropod dinosaur that lived in Germany and France during the Late Jurassic period. This little pack hunter probably ate bugs and small lizards. In fact, the first fossil skeleton of this dinosaur had the remains of its last meal, a lizard, still in its stomach.

Compsognathus is one of those dinosaurs around which some controversy swirls. Some paleontologists feel that, like the much larger Tyrannosaurus, the little Compsognathus had only two fingers. Others feel strongly that it had three. Since there are only two known fossils, and the bones are not perfectly preserved in an articulated (as they were in life) manner, it may take more discoveries to solve this issue.

Compsognathus is considered an important link in the study of bird evolution. The original fossil of this dinosaur was found in the same place as Archaeopteryx, the early feathered reptile. Compsognathus shares a number of characteristics with this creature, and close relatives of Compsognathus like Sinosauropteryx that had their skin preserved show the group had downy feathers in reality. This is one of those interesting dinosaurs where scientists hope to find more specimens to learn the answers to many questions.[1]


Like all of InGen's cloned theropods, the cloned Compsognathus had pronated wrists and lacked feathers. The Compy clones seem to have only functional two fingers on their pronated hands with a vestigial third finger, which was once believed to be true (at least having only two fingers, anyway) based on a fossil, but a different fossil showed it had 3 functional fingers in life instead, making InGen's Compies inaccurate. It is slightly larger than the originals, being 1.5 meters (5 ft) in length instead of 1.2 meters (4.2 ft).[2] The Compies lived on a diet of lizards, insects,[3] and would sometimes scavenge given the opportunity. However, the cloned Compsognathus would use a unique way of pack hunting to kill prey larger than them. A Compy pack would send a scout to confront the potential prey and while the intended target interacts with the scout, the rest of the pack rushes in and overwhelms their victim.[4] It was green in color having multiple shades with dark striping across their back some also seem to have shades of red and blue as well and have a yellow underbelly.


During an intriguing encounter on the shores of Sorna, a Compsognathus approached a solitary young girl who was peacefully enjoying her time on the beach. Displaying no signs of aggression, the Compsognathus calmly accepted the food offered by the girl. Unbeknownst to her, this initial interaction attracted the attention of other Compsognathus individuals, who stealthily gathered around her, hoping to share in the food. The sudden arrival of these small dinosaurs went unnoticed by the girl, who remained unaware of their presence until they began to leap and encircle her, potentially causing her distress before potentially launching an attack.

In an intriguing encounter, a Compsognathus, seemingly unafraid of the lone human, approached out of curiosity. It remained uncertain whether this particular Compsognathus belonged to the same pack that had previously attacked a little girl. The presence of multiple individuals might make them more formidable hunters, hence their lack of fear towards a solitary human. However, the Compsognathus was startled and deterred when it inadvertently encountered an electric shock.

Subsequently, it is plausible that the Sorna Compsognathus, having regrouped with its pack, resumed tracking the human. Their behavior indicated a persistent interest in following the human's movements. The human, perceiving the potential threat, attempted to intimidate the pack by charging at them while emitting vocalizations and even resorting to throwing rocks. This display caused the Compsognathus to scatter momentarily, but they persisted in their pursuit. Ultimately, the pack launched a fatal attack on the human, resulting in his demise.

The Nublar Compsognathus exhibit pack behavior similar to their counterparts on Sorna. In an intriguing encounter, they attempted to hunt Ben, but fortunately, he had the protection of Bumpy, the juvenile Ankylosaurus. Bumpy displayed her strength by charging at the Compsognathus, which effectively frightened them away. However, the Compsognathus returned later, taking their time to observe Ben when Bumpy had disappeared due to Ben's actions. They cautiously approached from different directions, but were ultimately scared off by Ben. This observation suggests that these particular Compsognathus may not yet possess the aggression necessary to attack a human, unlike their counterparts on Sorna.

Nublar Compsognathus, similar to other Compsognathus species, display a strong attraction towards shiny objects, which they tend to pilfer from humans and bring back to their nests.

The campers stumbled upon the coexistence of Compsognathus and Blue, a Velociraptor, in the same territory. Compsognathus will protect themselves from larger predators to reside in elevated areas. However, when individuals try to evade Blue from below, they often seek refuge in the surrounding foliage. Unfortunately, their attempts prove futile as they eventually become prey to Blue's predatory instincts. This behavior suggests that the Compsognathus individuals are likely to venture out for necessary resources such as food and water only when they perceive Blue's absence.

Nublar Compsognathus, a small dinosaur species, seizes the opportunity to prey upon Blue or any other dinosaur that may be trapped due to the jeep's confinement. Unfortunately, Blue finds herself unable to defend against these predators in her trapped state. Usually they flee when they see larger dinosaur approaching them.

Compsognathus exhibit a behavior of nibbling on wires.



Compsognathus was created[4] by InGen inside their compound[3] on Isla Sorna[4][3] where the juveniles were taken care of by the workers there.

They were not planned for Jurassic Park on Isla Nublar,[5] but after the 1993 incident InGen reported that there was a population of 28 individuals on the island.[6] It suggested that they managed to reach the island via hiding on InGen cargo vessels between Nublar and Site B.[6]

In Jurassic World: Camp Cretaceous, it was confirmed that Jurassic World did have Compsognathus on exhibit. The series also confirmed that the species has "trace amounts of venom" in its bite, which was previously a novel canon element unlike the original.

The Lost World: Jurassic Park[]

Isla Sorna Incident[]

When the Bowman family went to Isla Sorna for vacation, Cathy Bowman encountered a Compsognathus scout on one of the island's beaches. She liked the small dinosaur and fed it some food. But to her and her family's horror the rest of the pack emerged from the nearby forest to attack Cathy, though she survived the attack.


Compsognathus in The Lost World

When Cathy's parents sued InGen for the injuries she sustained from the dinosaurs, this set course the events of the Isla Sorna Incident of 1997 where InGen's CEO John Hammond was fired and succeeded by his nephew Peter Ludlow who hired a team to capture dinosaurs living on Isla Sorna for Jurassic Park: San Diego whom he wanted to revive.[4]


During the Hunters' capture of the dinosaurs on the Game Trail, hunter Dieter Stark encountered a Compy whom he attacked with his taser for the fun of it.

The hunters captured several Compsognathus and two of them were showcased by InGen CEO Peter Ludlow during his transmission to the board of his company. The Gatherers later freed at least three Compies from the encampment. The individuals in Ludlow's tent were most likely killed when the captured Triceratops was freed by the Gatherers. It is unknown what became of the other individuals and whether or not they survived the chaos in the camp.

When Dieter Stark went to urinate in the woods of Isla Sorna after the skirmish at the InGen Harvester Encampment, he encountered another Compsognathus. He proceeded to tase it like he had done the previous one he encountered before. This individual turned out to be a scout and its pack pursued Dieter who had gotten lost in the woods. They attacked once he tripped on a slope while trying to get back to his group.

He managed to survive the attack and scared the pack away once he had removed them from his body. But the pack soon returned to attack Stark again at a stream where the Compies succeeded in killing him, likely because he had been weakened by their venom.[4]

Jurassic Park III[]

Rescue of Eric Kirby[]

During his stay on Isla Sorna, 12-year old Eric Kirby learned to use Tyrannosaurus urine to repel Compsognathus.[3]

Compsognathus were present during the battle with the Spinosaurus and Tyrannosaurus rex as the smaller dinosaurs ran for their lives as the two theropods fought to the death.

When Dr. Alan Grant visited the truck that Eric was living in it a pack of Compies arrived near their location but they did not attack them and instead fed on some insects.[3]

Jurassic World: Camp Cretaceous[]

Compies appear numerous times in Camp Cretaceous. For example, in Season 1, a Compy pops up at a vehicle being used to give the group of campers a ride to the camp itself. In Season 3, the group of campers meet a large amount of Compies at the old Visitor Center, after one of them stole a compass. After Blue gets trapped, she is nearly eaten alive by a pack of Compies before the campers rescue her. In Season 4, a lone Compy stowed away on the campers' boat and is then shipwrecked on Mantah Corp Island along with the campers when the Mosasaurus attacks. It follows the campers to the desert and redwood forest biomes when it is sadly killed by a BRAD in Turning Dr. Turner. In Season 5, Laura Molina gets annoyed by a Compy near the old Visitor Center and throws a rock at it. As a result, she is subsequently devoured by a pack of the little dinosaurs, similar to the fate of Dieter Stark.

Jurassic World: Fallen Kingdom[]


Compies in the jungle of Isla Nublar in Jurassic World: Fallen Kingdom

It is revealed that there are surviving Compsognathus populations on Isla Nublar, but will now face an impending danger, alongside many other creatures, in the form of an erupting volcano.

They are seen running alongside several other species from Mount Sibo.

Several Compies have been rescued from the island alongside many other species in order to be sold at auction,[7] and they are later seen running out of the Lockwood Manor after Maisie released all of the captured animals. They eventually eat some of Eli Mills’s remains after the latter was killed and devoured by the T. rex.

According to DPG, Compsognathus was subject to cruelty some time in the past.[8]

Battle at Big Rock[]

Compsognathus makes a brief cameo in the short, chasing a little girl during the end credits.

Jurassic World: Dominion[]

In February 2021, Kayla Watts shipped twelve Compsognathus to Biosyn's sanctuary.[9]

In 2022, the Department of Prehistoric Wildlife has confirmed sighting of Compsognathus in Brazil eating trashes, Salem, Oregon (as an angry individual is caught in a rodent trap), Allendale, Wyoming (under its scene in Battle at Big Rock), Petit-Caux, France (as they cause power outages due to their nests), Weurt, Netherlands (where one challenged a YouTuber, TheGamingBeaver, into a staring contest), and Rome, Italy (where like the Pteranodon in Spain, it steals a man camera as it is attracted to the shining light).[10]

At least five Compsognathus can be seen in a cage at the Amber Clave Night Market in Malta. Later, as Rainn Delacourt tries to escape Owen Grady, he knocks over the cage, allowing the Compies to escape and jump onto Owen. Luckily, Owen manages to remove them from his body and continues to pursue Delacourt. It is possible that the Compsognathus might escaped the market and lives in the wild and probably ending up in the Biosyn Sanctuary.

Behind the scenes[]


Concept art of Compsognathus by William Stout for the canceled Jurassic Park animated series.

Compsognathus in the films fills the role of the similarly named and similarly sized Procompsognathus. Dieter Stark's death at the hand of a Compsognathus swarm in The Lost World: Jurassic Park is based on John Hammond's death in which a pack of Procompsognathus kills him while he is injured in the chapter "Hammond II" of the Jurassic Park novel. Curiously, in the behind the scenes video for the Compsognathus animatronics that attack Dieter in the film Christian Colquhoun of Stan Winston Studios refers to the Compies as Procompsognathus.[11]

When Dr. Robert Burke encounters Dieter Stark with a Compsognathus during the capture of the dinosaurs on the Game Trail he identifies it as "Compsognathus triassicus". There is no such species of Compsognathus known by this name, rather it was a combination of the genus Compsognathus and the species Procompsognathus triassicus. Though this is merely an error by the scriptwriters, it is unknown if there is a species called "Compsognathus triassicus" in the film canon or if it was simply an error that Dr. Burke made. Despite the possibility that the film's Compies are actually Procompsognathus, paleontologist and consultant for the films Dr. Jack Horner as said in the past that they were indeed Compsognathus.[12]

As a thank you to Steven Spielberg, Industrial Light and Magic created an animation that features a pack of Compsognathus wearing bow ties, top hats and holding canes tap dancing. It was included in Beyond Jurassic Park and in the The Lost World: Jurassic Park Blu-Ray.

The Lost World: Jurassic Park popularized Compsognathus. Post-TLW games, like Tomb Raider III, also feature Compsognathus as portrayed in the film.
