Stegosaurus is a herding animal but becomes territorial with each other when there are more than nine individuals, a problem encountered on the Isla Sorna map when there are several loose on the island. It is advised therefore to house them in other exhibits or sell any excess Stegosaurus. Stegosaurus can also be kept with a number of other herbivores. Vaaler, J. E. [Jens Erik]. (July 14, 2021).

Parasaurolophus, despite appearing physically in the first three films, is absent from the scripts of the aforementioned films, or is at least not mentioned by name. In Jurassic Park, the Parasaurs appear to have filled the role of both Hadrosaurus and Maiasaura from the novel, most notably the former as both Hadrosaurus in the novel and Parasaurolophus in the film lived alongside a species of sauropod at a watering hole. a b Maidment, S.C.R., 2010, "Stegosauria: A review of the body fossil record and phylogenetic relationships", Swiss Journal of Geosciences, 103: 199-210 When the ship Arcadia left Isla Nublar, one seemingly distressed adult Stegosaurus could be seen calling out from its cage. From the 1950s onwards, the geology of China was systematically surveyed in detail and infrastructural works led to a vast increase of digging activities in that country. This resulted in a new wave of Chinese stegosaurian discoveries, starting with Chialingosaurus in 1957. Chinese finds of the 1970s and 1980s included Wuerhosaurus, Tuojiangosaurus, Chungkingosaurus, Huayangosaurus, Yingshanosaurus and Gigantspinosaurus. This increased the age range of good fossil stegosaurian material, as they represented the first relatively complete skeletons from the Middle Jurassic and the Early Cretaceous. Especially important was Huayangosaurus, which provided unique information about the early evolution of the group.Later, Parasaurolophus was one of the many dinosaurs that Dr. Alan Grant and the Kirby family saw on a riverbank. [5]

The stegosaurian pelvis was originally moderately large, as shown by Huayangosaurus. Later species, however, convergent to the Ankylosauria developed very broad pelves, in which the iliac bones formed wide horizontal plates with flaring front blades to allow for an enormous belly-gut. The ilia were attached to the sacral vertebrae via a sacral yoke formed by fused sacral ribs. Huayangosaurus still had rather long and obliquely oriented ischia and pubic bones. In more derived species, these became more horizontal and shorter to the rear, while the front prepubic process lengthened.
