Procompsognathus

"The compys didn't look dangerous at first sight. They were the size of a hen and walked nervously like a hen. But he (John Hammond) knew that they were venomous. Their bites delivered a slow-acting poison that they used to kill wounded animals."

- Jurassic Park (novel)

Procompsognathus (pronounced /ˌproʊkɒmpˈsɒɡnəθəs/) is a genus of small theropod dinosaur that lived during the Late Triassic Period, about 222 to 219 million years ago. Procompsognathus was named by Eberhard Fraas in 1913. He named the type species, P. triassicus, on the basis of a poorly-preserved skeleton found in Württemberg, Germany.

Procompsognathus may have been about 1.2 meters long (4 ft). A biped, it had long hind legs, short arms, large clawed hands, a long slender snout with many small teeth, and a stiff tail. It lived in a relatively dry, inland environment and may have eaten insects, lizards, and other small prey. They were named Procompsognathus by in 1913.

Jurassic Park (novel)
In Michael Crichton's novelsJurassic Park and The Lost World, Procompsognathus (often referred to as "Compys") are one of the extinct species recreated through genetic engineering. Crichton portrays these dinosaurs, like its larger coelophysoid relative Dilophosaurus, as having venomous saliva, a characteristic invented for the novel and (obviously) not supported by fossil evidence. This is likely DNA splicing. Their saliva has a foam-like structure and has a high concentration of ; which can trigger an. Their venom has a mild narcotic effect, making the victim feel sleepy and drowsy, and altogether content.

He also portrays them as scavengers and coprophagists (eaters of feces), useful in keeping the park clean of sauropod excrement, a well needed solution. They travel in large packs, and prefer to feed on small, solitary, crippled, dying, or dead animals when not feasting upon the copious amounts of feces left behind by InGen's larger creations. Compys have a tremendous sense of smell to find corpses.

Compys normally don't walk in the night. At night they normally sleep in trees until dawn.

Procompsognathus is the first dinosaur that appears in the novel. The Compys are able to escape the park through the river, which is not guarded with an Electric Fence or cameras, so they can reach the harbor and sneak into the boat that ferries between Isla Nublar and Puntarenas.

Three Compys kill a baby in a local hospital. A compy hurts Tina Bowman on a deserted beach. She showed an intense allergic reaction and is taken to the Clínica Santa María in. This triggers a series of investigations to the strange creature:

Clínica Santa María: saliva is investigated. It contained many proteins with a high. But when Martin "Marty" Guitierrez identified the creature as a mere Basiliscus amoratus with a three toed genetic anomaly the investigation is canceled. Martin Guitierrez then finds a half-mastificated procompsognathus and sends it to the to be investigated by Dr. Simpson. The University's Laboratory for Tropical Diseases analyses the blood from the specimen. The blood showed no significant reaction to viral or bacterial. A of the specimen is sent to Alan Grant, who immediately identifies it as a Procompsognathus.

The receives a saliva sample from the Clínica Santa María. The Saliva contained a high level of serotonin. The saliva contained a huge protein with a mass of 1.980. It turned out to be a primitive form of. They also found traces of gamma-amino methionine hydrolase.

In the chapter Bungalow, Harding encounters a pack of Compys running towards the body of Dennis Nedry, but has to call off his quary before finding Nedry.

At the end of the novel, the main pack of compies find an injured John Hammond, who, with a broken ankle, is unable to walk, or even crawl. They ultimately finish him off after he passes out from their narcotic venom.

Most of them are killed in the napalm bombing and while the others somehow reach the mainland.



The Lost World (novel)
Procompsognathus is seen feeding on the feces of Parasaurolophus. Richard Levine sees that they only feed on fresh feces, which makes him think there is some kind of hormone in the fresh feces. When the takes a sample of the dung, a Compy bites him on his ear. Luckily it was a minor bite and he suffered no ill effects except a predicted "slight encephalitis". Lewis Dodgson while sleeping on the ground near the shed and the Rex nest after running away from the Tyrannosaurs   was starting to be eaten by some Procompsognathus before he ran into the shed.

Kills

 * John Alfred Hammond (Ironically the man who created the animals)

The Lost World: Jurassic Park (film)
In the film adaptation of The Lost World, Procompsognathus were ultimately replaced with the distantly related coelurosaur Compsognathus. However, Robert Burke refers to them as Procompsognathus triassicus (triassicus being the type species of Procompsognathus).

A group of Compsognathus stalk Dieter Stark when he gets lost in the jungle. Though they were most likely hunting him because he was alone, it is ironic that he is killed by them, because he had treated at least two Compys cruelly earlier. This scene is the allusion to the death of John Hammond in the novel.

Trivia

 * Although every scientist in the novels claim the compies are scavengers, they always seem to be feeding on creatures still alive, although usually injured.
 * Even though InGen had successfully solved their dung problem, but the animals made it pretty clear they weren't safe for free-roaming-zoo scenarios
 * Procompsognathus and Dilophosaurus are Coelophysoidea,this dinosaur are venomous,in the movie series appears the Segisaurus this dino is a Coelophysoidea,for this is venomous in jp universe
