Zoo Tycoon 2 features three gameplay modes: Campaign, Challenge and Freeform. Guests will visit the zoo to see the animals, and they also have needs that need to be fulfilled through scenery and buildings (hunger, thirst, bathroom, seating, entertainment). The Zoo Tycoon 2 gameplay revolves around creating suitable exhibits for animals through habitat modifications (ground cover, water, elevation, foliage and rocks and a variety of items including food, enrichment and shelter) which fulfill the animal's needs (habitat, hunger, thirst, stimulation, privacy, sleep, social, exercise). The Extinct Animals models are the ones used in the game.See List of animals in Zoo Tycoon 2 for a full list of animals in the Zoo Tycoon 2 games. The pack does conflict with the Extinct Animals versions, but have their models included in addition to the new ones. However, it can still be purchased via URL on the Oberon Media website, even though it is not linked.

Since the release of Zoo Tycoon 2: Extinct Animals, which includes more updated versions of all of the animals and items included in the pack, Dino Danger was taken offline from the Zoo Tycoon website and can no longer be downloaded. Eating guests does not help satisfy hunger levels. The carnivores do eat guests, but only adult men and not women or children, most likely for user-friendly issues. There were four dinosaurs in the pack, all from the Cretaceous period. It has now been replaced by the Extinct Animals expansion pack. It could be downloaded from the Zoo Tycoon website and Oberon Media website for $4.99 via credit card.

Zoo Tycoon 2: Dino Danger Pack was a downloadable bonus pack for the game Zoo Tycoon 2 released on July 2006.
