After leaving the theater, guests found themselves in the Primeval Diorama, where they could no longer see Ellen and or Bill (although they could hear their voices as they proceeded through the scenescenes). The In fact, the first thing that guests heard in the Primeval Diorama was Ellen talking to a roaring dinosaur, who she had mistaken for Bill. After the real Bill called her over, the two reunited and moved with guests through the scenediorama. The first creatures that guests encountered on their journey was a giant millipede and an Edaphosaurus. Further on, guests could see a Brontosauruses eating swamp plants. The large dinosaur then sneezed on guests, while nearby, duck-billed Trachodons could be seen bathing in a small body of water.
Up ahead, guests saw perhaps the most recognizable scene in the attraction- an Allosaurus and a Stegosaurus fighting on a cliff. Nearby Pteranodons were perched around an erupting volcano. Further , and further on, guests could see Ellen fighting off an Elasmosaurus with a stick. As she defended herself against the dinosaur she said:

Listen mister, don't give me that attitude! Bill! I could use a little help here. Down, boy. I -- I said, down, boy!"}}
