The “near crested reptile” was found in Western North America and described by William Parks in 1922. Parasaurolophus lived in the Late Cretaceous Period about 80 to 73 million years ago. It was 7.6 meters (25ft) in length, 4 meters (13ft) in height and weighed 4 tons. Parasaurolophus can be found on both Isla Nublar & Isla Sorna gathered in herds that are usually found around large sauropods. Laura Sorkin also had a male herd of Parasaurolophus on Nublar as part of her private stock in her isolated section of the island. Parasaurolophus are known to be hunted commonly for food by Tyrannosaurus rex.
The only way to identify genders of the Parasaurolophus is to look at their color. Females vary in color with blue or black horizontal, possibly lateral stripes, with a base color of green and maybe a yellow, white, brown, or grey underbelly. Males are often brown and show a hint of red. While it is said that the female Parasaurolophus at Jurassic Park have a slight curvature to their skulls, the skull is generally exactly the same as the males after closer investigation and this makes the sexes of the species indistinguishable from another save for their separate colors. It is also worthy of notation that the Parasaurolophus possibly may have an individual ranking system where dominant animals happen to feature different vibrancy of red on their crests and neck as this can be seen in many individuals in their numerous appearances in the series.
The Parasaurolophus herd in Isla Sorna in 2001 also seems to feature this type of red in varying shades on their necks and around their crests as well. This looks more deliberate as intended to hint at individualism among the animals present and possibly to indicate gender differences as well. Given initial appearances on both Isla Nublar and Isla Sorna it would seem that herding between the species seems to have been into both male and female herds respectively. Especially if we take the 1993 Nublar Incident and 1997 Isla Sorna Incident into account only.
Parasaurolophus were one of the dinosaur attractions housed in the Jurassic World theme park on Isla Nublar. They were housed in the Gallimimus Valley, Gyrosphere, Petting Zoo, and Cretaceous Cruise attractions where they mixed with other herbivorous dinosaurs. Most notably, two Parasaurolophus can were seen during Zach and Gray Mitchell‘s tour of the Gyrosphere valley, engaging in a dominance fight in the background. Both of which held similar coloration patterns to the males seen on Sorna.
After the fall of the Jurassic World theme Park on Isla Nublar, the Parasaurolophus were left to roam free on the Island. They were one of the fourteen species of dinosaur that were removed from Isla Nublar before the eruption of Mt. Sibo by Ken Wheatley‘s team of poachers. At least one Parasaurolophus specimen was transported from the island to the mainland via the ship Arcadia.
After arrival on the mainland, the animals were then transferred to Lockwood Manor for auction. After Blue‘s escape from captivity, a gas leak in the lower level of the manor caused the animals to begin to suffocate in their holding cells. A lone Parasaurolophus can be seen amidst the other dinosaurs, about to choke from the fumes in the moments before Maisie Lockwood made the decision to free all of the animals, ensuring that the Parasaurolophus would be able to escape into the wild.
Behind the Scenes Information
Production wise we know that from The Making of The Lost World (p.25) that gender differences were intentional in the design phase of pre-production to indicate differences between male and female versions of the animal.
“‘We had to design new paint schemes not only for the new dinosaurs, but for some of the already-designed dinosaurs from the last movie,’ Winston explained, ‘because now there were male dinosaurs, as well as females; and typically in nature the males of any species are far more brightly colored. We also wanted to make sure that the audience would be able to tell the males and females apart. It was a great of fun to run the gamut of color and come up with interesting designs. The colors on the females for the first film had been fairly subdued; but with male animals, there were may more possible colorations.’”
If the herds are indeed persistently gender divided, some have postulated that the Parasaurolophus females are territorial, and the source from this comes from an informational video at Isla Adventura. There is a concept art piece featuring a design of the female Parasaurolophus that doesn’t quite bare a similarity to what we see in the films as well. The many variances seen in Parasaurolophus could even be another example of versioning by InGen and we are in fact seeing both males and females together. We just can’t say for certain based on the information we have available to us.
