Achillobator (Achilles hero) was a dromaeosaurid dinosaur that lived during the Late Cretaceous period, in what is now Mongolia. Described by Altangerel Perle in 1999, it was one of the largest dromaeosaurids known, with the only known specimen to be estimated at nearly twenty feet long. Like it’s fellow cousins, Achillobator had a sickle-shaped claw on each foot, which would have likely been used for hunting prey.
In Jurassic Park: Trespasser, the Velociraptor is one of the most common enemies that Anne encounters on her trek across Isla Sorna. In Dr. Hammond’s dialogue, InGen’s first cloned Velociraptor was released into Isla Sorna on April 22, 1985.
Isla Sorna’s Velociraptors are organized into three tribes, which were Tribe “A”, Tribe “B” and Tribe “C”. Velociraptors apart of Tribe A closely resemble the male Velociraptors seen in The Lost World: Jurassic Park, with an orange body, white underside, and black stripes. Tribe A Velociraptors were common from the beginning of the game until Anne reached the “Industrial Jungle” level, at which Tribe A Velociraptors become less common and are replaced by Tribe “B” Velociraptors.
Tribe B Velociraptors differ vastly from Tribe A, where they have a beige-yellow body, with red splotches marked with black trims. These raptors would soon be replaced by the Tribe “C” Velociraptors, which oddly have two appearances; one breed has a yellow body, with black stripes accented with orange, whereas the second breed has a dark black body, with red striping across the body. The second breed was only seen once atop Mount Watson, spotted with a few of the regular Tribe C breeds.
Near the end of the game, Anne will encounter the “Alpha Raptor”, which is essentially a Tribe “C” Velociraptor twice as large as a regular Velociraptor. This raptor is much harder to kill and is surrounded by regular Tribe C Velociraptors. The Tribe C breeds first appeared in “The Ascent: Part 1” level and stopped appearing at “The Summit” level, which is the final level of the game.
