Dryosaurus is the only 1 Star Dinosaur in JPOG, and is usually the earliest Dinosaur that one can use in their park provided the starting Dig Site Morrison Formation Site A.


Typically it tends to flock with others of their own kind, having a similar behavior to that of Gallimimus in-game. Compared to other Herbivorous dinosaurs in the game, it is relatively helpless outside of running away from predators, much like Gallimimus. Overall, it should act no differently from Gallimimus in-game. For some reason, Dryosaurus tends to die of malnutrition a lot, for no apparent reason other than the fact that it simply doesn't want anything to eat or drink.


Only a mere Low Security Fence is all you'll ever need to keep a Dryosaurus contained, and this same type of fence is all you need to keep the other Jurassic Herbivores in the same enclosure as well. If you plan on doing the latter, somewhere around 20-30 individuals is recommended as well as a large sized enclosure is necessary to contain all of these Herbivores with little to no issues. Dryosaurus gets along with every Herbivore in the game just fine.

Starting with Dryosaurus is not exactly the best idea, as it can be hard to keep visitors entertained with a mere 1 Star Dinosaur such as this, which means you may end up putting Ceratosaurus in the park first instead. Dryosaurus is, however, the most inexpensive Dinosaur in the game, but this is usually migitated by the fact it prefers to live in large numbers. Overall, Gallimimus, with similar behavior and a 3 Star Rating, would make a more popular alternative to those who didn't start with Morrison Formation Site A as their initial Dig Site.


  • It is tied with Homalocephale and Velociraptor for the smallest Dinosaur in JPOG, at 3 Meters in Length.
  • It is the only 1 Star Dinosaur in the game as mentioned throughout the article.
  • Dryosaurus is one of only three Herbivores whos favourite dinosaur is their own species, the other being Gallimimus and Ankylosaurus . This is due to having no close relatives in game (Its closest relative is the Iguanodon, which was cut from the game).
