Pteranodon longiceps/P. sternbegi (?)
The “toothless wing” was found in western Kansas in 1870 and described in 1876 by Othniel Charles Marsh. It is actually a pterosaur, not a dinosaur. P. longiceps was up to 7 meters (23ft) in wingspan, almost 2 meters (6.6ft) in length and weighed 50 pounds (22kg). Hunting mainly fish and with a light fur covering its body it lived in the Late-Cretaceous Period about 89 to 75 million. Pteranodon longiceps is seen perching on a tree watching a herd of Stegosaurus and the Tyrannosaurus male, female, and infant reunite.
P. sternbergi was collected by G.F. Sternberg in 1952 and described by Harksen in 1966 in the lower portion of the Niobrara Formation. It is actually a pterosaur, not a dinosaur. P. sternbergi had a wingspan up to 9 meters (30ft), 2 and half meters (8ft) in length and weighed 90 pounds (36kg). Hunting mainly fish and with a light fur covering its body it lived in the Late-Cretaceous Period about 99 to 89 million years ago.
P. sternbergi is proven to be on the island by the following, Roland’s Dinosaur guide, the trailer’s screensaver, and in several drawings and models made for the movie we can see photo evidence of it but it is never seen alive on film in any scene. It has been suggested that the intended use was for this species to be the male sexually-dimorphic version of the P. longiceps species seen at the end of The Lost World: Jurassic Park where science would say otherwise. For the intents and purposes of the Encyclopedia we’ve treated them as to what the film-makers possibly and inadvertently intended while scientifically pointing out the obvious differences between P. longiceps and P. sternbegi. Some quotations to back this line of thought up of the species being sexually dimorphic of one another are found below. These quotes can found in the Making of The Lost World: Jurassic Park book page 25.
“‘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 garmut 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.’”
“As they had for the first film, the designers at Winston studio adhered closely to paleontological fact-or, in the absence of fact, paleontological theory- in their dinosaur renderings and sculpters, ‘We were very concerned that whatever we came up with made sense scientifically,’ Winston said, ‘so we drew from the science of paleontology. But since that science is limited in detail and has to rely on bone structure and hypothesis, we also drew from nature-what we see around us today.’”
“‘We looked at the color schemes and hide textures of living animals, especially those that live in a similar environment and have a similar lifestyle to the dinosaurs. The third thing we pulled from, of course, was imagination and instinct. No one really knows what these animals looked like; but our instincts told us if what we’d come up with made sense.’” (Duncan 25)
We know that a species of Pteranodon is proven to be present on Isla Nublar from the mural in TLW in the Operations Center, culminating with the fact that during the luncheon scene it was stated by the audio recording that Jurassic Park was to feature “majestic flying reptiles” on one of its rides.

Pteranodon longiceps “hippocratesi” (*)
The “toothless wing” was found in western Kansas in 1870 and described by Marsh in 1876 by Othniel Charles Marsh. It is actually a pterosaur, not a dinosaur. It was 9.7 meters (32ft) in wingspan, 3.1 meters (10.2ft) in length and weighed 200 pounds (90kg). This “hypocrite” species, known so from the name meaning “toothless wing” but seen with teeth, is derived from its appearance in Jurassic Park ///. Little is known about the creation of this species.
P. hippocratesi was born with teeth and was seemingly very aggressive. They were then contained in what became known as “The Bird Cage” (the aviary) on Isla Sorna, never to be released into the wild when Isla Sorna was evacuated. It is known that these animals are carnivores, devouring fish caught from the river that runs through their aviary, but film evidence shows that they are fiercely territorial and will feed their young anything, including humans.
P. “hippocratesi” was born with teeth and was seemingly very aggressive. A plausible explanation for this is that DNA contamination occurred, but there’s no evidence for this in this species, but there is in other species, specifically Dilophosaurus. There also seems to be some evidence that the animals were under close watch and security because of the facilities in place to monitor them. Many observation stations, and a computer system is in place are witnessed in the background of the aviary’s entrance. This species is also shown to be present on Isla Nublar from when Gerry Harding is rescued by Billy Yoder and the other mercenaries hired by InGen.
As for sexual dimorphism being present we clearly see no variation, but conceptually before the film’s release the male had a maquette made of it and appears in numerous material. At least this is presumed to be the male, but there is no source for this.
