Torosaurus was a large ceratopsid dinosaur. Its name means "perforated lizard", although often incorrectly interpreted as "bull lizard". It very much resembled its cousin Triceratops, but had a much longer frill, with two large holes (or fenestrae). In 2009 researchers under supervision of Jack Horner argued that Torosaurus was the oldest form of Triceratops. The massive frill of Triceratops would grow longer and thinner in time, until it may have had the same holes as seen in Torosaurus. However, this has since been disproven, as young Torosaurus fossils have been found. Torosaurus may have lived in herds, like many of its relatives, but experts are not sure, since no fossils have been found in large numbers. It was long thought to have the largest skull of any animal in history, but it seems in recent years that Pentaceratops has topped its record.

Jurassic Park III: Park Builder

It is No.100 of the Herbivore Threes that can be created in Jurassic Park III: Park Builder.

Jurassic Park: Explorer

Torosaurus appeared in Jurassic Park: Explorer.

Jurassic Park: Operation Genesis

see Torosaurus/Operation Genesis

In Jurassic Park: Operation Genesis, Torosaurus is featured as a two-star large herbivore. It is much more docile than Triceratops but still uses its horns defensively. They are much more territorial than Triceratops, and will rut with each other in competition for dominance of the herd. It will occasionally attack Land Cruisers, albeit much less often than its larger, more aggressive cousin. They're capable of fighting all large and small carnivorous dinosaurs, but they usually attack small carnivores and avoid large ones.

The coloration is a greyish lime green with a brown outline on the frill and the back, with an orange on the brown outline on the frill.

Jurassic Park: The Game

Torosaurus is the adult form of Triceratops as revealed from Dr. Laura Sorkin's research on Jurassic Park's Triceratops herd.[1]

Jurassic Park: Builder

see Torosaurus/Builder

Torosaurus is one of the available dinosaurs in Jurassic Park: Builder. In the mission Surprising Find Alan Grant will ask the player to create a Torosaurus. Alan Grant says he hasn't seen a Torosaurus fossil since his student textbook, so he never thought of seeing one in the park.

Jurassic World: Evolution

seeTorosaurus/JW: E

Torosaurus has been confirmed to appear in Jurassic World: Evolution.

Behind the scenes

Torosaurus being a mature form of Triceratops in Jurassic Park: The Game is an allusion to Jack Horner's research in 2009, even though this has since been disproven.
