This is Dryosaurus, a little plant-eating Jurassic dinosaur.
— Korrina describing Dryosaurus

Dryosaurus (name meaning "Oak Lizard") is a genus of ornithopod dinosaur that originated during the Middle Jurassic period in what is now North America and Africa. Measuring around 3 meters long and weighing 170 pounds, it is perhaps the largest of the small ornithopods.

In the episode "Time of Giants Part II: Ballad of Big Al", a large group of Dryosaurus was brought back to the park from Wyoming of 145 million years ago. They reside in the "Ornithopod Paddock" with their other relatives.

FactsEdit

Era & DiscoveryEdit

Dryosaurus lived in North America during the Middle to Late Jurassic Period from 176–145 million years ago. Dryosaurus was first discovered by Samuel Wendell Williston in 1876.

Physical AttributesEdit

Dryosaurus stood 5 feet (1.6 m) tall, measured 10–14 feet (3–4) long, and weighed 77–90 kilograms (170–200 lbs.), a rather large member of its family in comparison with the averagely sized species that is related to it.

Dryosaurus also had a horny beak and cheek teeth as well as a long neck, long, slender legs, and a long, stiff tail. A quick and agile runner with strong legs, Dryosaurus used its stiff tail as a counterbalance. Its arms, however, with five fingers on each hand, were short.

Behavior & TraitsEdit

Like many dinosaurs, especially one like them such as Othnielia and Leaellynasaura, Dryosaurus lived in huge groups in both open lands and forests. Whenever the herd was feeding, one adult, the Sentry, kept watch.

Dryosaurus was still a small, swift herbivorous dinosaur under the threat of predation at all times, and so its main defense was to simply outrun its attackers with bolts of lightning-fast speed. A slightly larger relative of Othnielia, Dryosaurus relied on their speed and agility to survive. Even large predators like Allosaurus could not possibly run down such swift prey like these.

Trivia Edit

  • Of all the small ornithopods brought to the park, Dryosaurus is the largest as well as the first.
  • The sound effects of Dryosaurus are altered bird sounds, rainforest birds, such as peacock, duck, parrot, hawk and eagle chirps, and turkey sounds.
