Troodon

"You don't want to be left alive by this Dinosaur" - Tellltale Games

Troodon (or Troödon) was a small Theropod that lived during the Late-Cretaceous period. It was one of the most intelligent dinosaurs that ever lived. Troodon could reach a length of 2.4 metres (7.9 ft) and a weight of 50 kilograms (110 lb). Despite sharing similar characteristics (which included a retractable sickle-claw), Troodon was not relatated to Velociraptor. Discovered in 1855, it was among the first dinosaurs found in North America.

The Lost World novel
Troodon has never appeared in any films or novels. However, it was mentioned in The Lost World novel. Troodon was only mentioned in the novel, when Dr. Richard Levine was talking to Dr. Marty Guittierezz, about a colleague of his named John Roxton, whom had discovered what he believed to be a Velociraptor skeleton in Mongolia. However, it was really a Troodon skeleton.

Jurassic Park-inspired games

 * Troodon appears in The Lost World: Jurassic Park (SEGA Genesis Game) video game.
 * Troodon is number. 039 of the Carnivore Ones that can be created in Jurassic Park III: Park Builder.
 * It is also possible to make a Troodon in Jurassic Park: Operation Genesis from a Velociraptor with mods.

Jurassic Park: The Game
Troodon is an all-new dinosaur in the Telltale's Jurassic Park: The Game. It was originally the unnamed nocturnal dinosaur in the game, but has since been revealed. It is a poisonous creature, passing on a toxic venom to its prey through a single bite. The venom causes hallucination in its victims, slowly making them suffer. What we already know is that a pack of them attacks Nima.

Trivia

 * Troodon is the first nocturnal predator to be seen in the Jurrasic Park film canon.
 * For unknown reasons, Telltale has given Troodon glowing eyes. This is possibly due to a Tapetum Lucidum, a tissue in the eyes of many animals that reflects light through the retina in order to see better in the dark.
 * Though never once mentioned in the tour, it can be assumed that the reason for the night-vision goggles was so people could see the Troodon at night.
 * Since nobody on Isla Nublar seemed to know about the Troodon, it was probably one of the dinosaurs that were not included on the InGen's list, such Spinosaurus and Ceratosaurus.
