Disambiguation Links – Psittacosaurus mongoliensis (IDW-DG)
Psittacosaurus, meaning “parrot lizard,” was a psittacosaurid ceratopsian described in 1923 by Henry Fairfield Osborn from remains found Mongolia and northern China; further remains have been found elsewhere in China, Russia, and possibly in Thailand. Psittacosaurus is related to better-known dinosaurs such as Triceratops and Protoceratops, though predated both of these by many millions of years. It lived during the Early Cretaceous period between 130 and 100 million years ago.
P. mongoliensis reached approximately 2 meters (6.5 ft) in length and weighed in excess of 20 kg (44 lbs). It was an herbivore, and likely had feathery integument on its tail, a feature which InGen’s recreation clearly lacks.
Psittacosaurus is not confirmed to exist on either Isla Nublar or Isla Sorna at present due to the canonical events of the Jurassic Park rides being an alternate reality based on the first films events. At the Hollywood and Islands of Adventure parks Site B is still in operational status as that’s where the Triceratops from the Discovery Trail were to be studied and the reasons for the seasonal status of the Triceratops Discovery Trail. Even though Psittacosaurus was listed as a dinosaur of Jurassic Park on the ride’s official site–which has since been taken down–as well as on 
The Lost World Official Site, it is generally not accepted as being part of the film canon due to the alternate reality nature of the rides. While it’s possible it still could exist tentatively on Isla Sorna there is no clear confirmation for this fact.
The status of Psittacosaurus is questionable as it was meant to be a dinosaur exclusive to Universal Studios theme parks, meaning that, in the alternate universe of the rides, it was cloned after the events at Isla Nublar. As stated in the timeline of the rides, Isla Sorna is still active and in use, only with the Incident at Isla Nublar forcing InGen to team up with Universal Studios; there is no reference in the films to Jurassic Park theme park being a subsidiary of Universal Studios or even being cooperative with InGen. The ride implies that a partnership was developed following the end of the Nublar project due to the incident and Universal bailing out InGen due to the wrongful death claims. We know this didn’t happen in the ride universe as the whole plan to harvest Isla Sorna by newly instated CEO, Peter Ludlow.
The rides are seemingly separate from the films, unless they are making a reference to the events of the films the precede them. Another reason as to why Psittacosaurus is not considered canon is because The Lost World Official Site is not considered to be an accurate representation of the film’s canon, the reason being that the site depicts Isla Sorna inaccurately and contradictory to the film (the map used on that site is actually more similar to the one from the original novel). It was also noted that The Lost World official Site had copied material from the ride’s official site.
