***Troodon*** is a genus of theropod dinosaur that originated from Late Cretaceous North America. A small but highly intelligent carnivore and among the first dinosaurs discovered in North America, *Troodon* possesses a deadly venomous bite, which it uses to subdue its prey. *Troodon* is included in the *Secrets of Dr. Wu* DLC and becomes available to the Hammond Foundation during the Security Division mission on Muerta East.

## History

*Troodon* was recreated for the original Jurassic Park, but was called to be terminated and scratched off of InGen's list for unknown reasons. An unknown employee hid the animals in a secret quarantine pen before they were released by Dennis Nedry when he turned off the power to the wild of Isla Nublar. By 1994 they either died in the wild or were killed off by the 1994 cleanup team. The embryos were subsequently destroyed, causing the regrowth of the animals to be impossible.

A *Troodon* named Jeannie was created sometime during Jurassic World's operation, as Dr. Kate Walker was working with her with a device known as the Dino Decoder, a device used to understand and predict dinosaur thoughts and emotions. After the Jurassic World Incident, she was set free on Isla Nublar with her new hatchlings.

## Characteristics

One of the smallest and among the most intelligent dinosaurs in the *Evolution* series, *Troodon* is a small carnivorous dinosaur that can be distinguished by their large eyes, small stature, serrated teeth, and venomous bite, which allows them to slowly subdue animals many times their own size. With long, thin legs that enable it to reach high speeds when chasing prey, *Troodon* would stalk its victims after biting; the toxins in its saliva cause hallucinations, followed by paralysis and finally brain death. Its name translates to "*Wounding Tooth*", in reference to its sharp incisors, while this theropod’s large eyes allow it to hunt in the dark. *Troodon's* large brain for its size – it stands at just over three feet tall – makes it one of the most intelligent dinosaurs; a level of intelligence that rivals its sister family, the dromaeosaurs or raptors.

### Behaviour

Without genetic modifications, *Troodon* are highly social animals and, as such, are comfortable in groups of between four and sixteen other *Troodon*. Similarly, they can tolerate large numbers of other dinosaurs in the same enclosure, preying on ornithopods, ornithomimids, and pachycephalosaurids, while avoiding large carnivores, armored herbivores, and sauropods. They will, however, fight back against small carnivores like *Velociraptor* and *Dilophosaurus* if attacked. *Troodon* also possess a venomous bite, much like a snake.

## Paleontology

The first identified *Troodon* fossil was a single tooth with serrated edges discovered by American paleontologist Joseph Leidy in the Judith River Formation in Montana, the location of a huge number of paleontological discoveries in 1855 to 1856. *Troodon* has proved difficult to classify; first identified as a small lizard, then a pachycephalosaur. *Troodon* was officially reclassified as a dinosaur in 1901 by fellow prehistorian Franz Nopcsa. Almost 100 years after the first tooth was discovered, *Troodon* was re-classified as a theropod due to its dentitional similarity to other known carnivores.

*Troodon* is a dubious genus from the Two Medicine Formation. *T. formosus* was once considered one of the most prolific species in North America, but in the recent years, most of its fossils were moved to the genera *Stenonychosaurus*, *Latenivenatrix*, and some teeth from Hell Creek were given to *Pectinodon*, leaving only the type specimen, a tooth, to the genera. This leaves no diagnostic traits that can differentiate *Troodon* from its relatives, although a handful of large undescribed specimens from Alaska could potentially be assigned to its genus in the future. The in-game *Troodon* most closely resembles the wolf-sized *Stenonychosaurus*. Interestingly enough due to the rules of Taxonomy, the group name for these two genera is still called *Troodontidae*.

The Troodontidae family is a sister group to the Dromaeosauridae. The family relation can be seen in the genus sporting a similar raised, sickle-shaped claw on the foot. This claw was likely used to aid in climbing as well as in pinning down prey underfoot while killing or eating, as early Mesozoic birds and modern birds of prey have similar claws. The serrations of its teeth are similar to those of herbivorous reptiles like iguanas, leading to frequent suggestions that it was an omnivore. The wear patterns on the teeth show that it preferred soft foods.

Troodon is believed to be among the most intelligent dinosaurs. This is based off the family having some of the largest brains for their body size across Dinosauria. While other factors beyond brain-to-body size ratio do exist when accounting for intelligence, it is still reasonable to assume Troodontids were among the smartest animals on the planet in their time. Some paleontologists speculate that *Troodon* was as smart as a modern-day fox.

*Troodon* was covered in feathers like all members of its family. In life, one could have favorably compared its appearance to a toothed bird with a long tail.

### Paleoecology

*Troodon* lived during the Late Cretaceous period, around 65-76 million years ago, in the Two Medicine Formation. It likely favored cooler climates, as most specimens have been found in northern and even Arctic areas, such as Alaska, suggest that this dinosaur may have preferred a cold climate, although teeth believed to have belonged to *Troodon* have been found as far south as Texas and New Mexico. It lived alongside of rich myriad of dinosaurs such as the hadrosaurs *Edmontosaurus* and *Maiasaura*, the armoured *Zuul* and *Edmontonia*, the ceratopsians *Centrosaurus* and *Pachyrhinosaurus*, as well as the ferocious tyrannosaurid *Gorgosaurus*, *Albertosaurus*, and *Daspletosaurus*.

## Behind the scenes

*Troodon* previously appeared in 2011's semi-film-canon *Jurassic Park: The Game*, and while it differed in appearance to *Jurassic World: Evolution's* *Troodon*, it also possessed a venomous bite.
