Nesting Grounds

The Nesting Grounds is a location in the film Dinosaur. An incredibly lush place, it managed to survive the destruction that the impact of the meteors caused.

As told in deleted scenes on the DVD release, the Nesting Grounds were first discovered by an Iguanodon named Old Gotama, whose fossilized remains still remain in the area. Since then, dinosaurs of numerous species have migrated to and from the area as a collective herd.

In the opening of the film, a nesting period in the Nesting Grounds turns from peaceful to chaotic when a Carnotaur sends various dinosaurs scattering and begins the journey of Aladar's egg to Lemur Island. Years later, after a meteor destroys the island, Aladar and his adopted Lemur family manage to make to the mainland and follow a saurian migration group and their desperate bid to find sanctuary in the Nesting Grounds. The catastrophe has blocked the main entrance off with an impassable wall of rocks, but an alternative route through a cave is opened up by Aladar and his friends.
