Parasaurolophus is an extinct genus of hadrosaurid (sometimes referred to as the hadrosaurs or duck-billed dinosaurs) from approximately 76.5–73 million years ago (late Cretaceous). It is a herd animal feeding on the park’s rich vegetation. The most stunning feature of the Parasaurolophus is the crest on its head. Scientists were unsure of its function until today. Some believed it was a snorkel for when the animal was in the water, others felt that it was used in combat. We now know that it serves for display and for communication, allowing the animals to remain in contact over distance by amplifying their loud cries.
Parasaurolophus was created by InGen in their compound on Isla Sorna where they spent their early lives being raised by the workers there.
The clones resembled the species Parasaurolophus walkeri but were shorter than the original animal, being 7 meters (23.25 feet) in length instead of 10 meters (33 feet). Although the clones are capable of walking on all fours and two legs, it mostly stood upright, nearly dragging its tail, unlike the original.
They had three skin variations, beige, greenish, and beige green. The ones seen in the Brachiosaurus Enclosure were also a greenish color with black stripes. Their crests would vary in color as well, with some having black, while others had dark gray crests.
When the clones were a few months old they would be transported to the neighboring island Isla Nublar to live as an attraction for InGen's Jurassic Park. They lived in the Brachiosaurus Enclosure.
