Sea Monsters - A Prehistoric Adventure - Dome Experience

About us

Travel back in time to when dinosaurs roamed the seas and meet Dolly – a curious and adventurous dolichorhynchops – as she travels through the most dangerous oceans in history. Along the way, she encounters long-necked plesiosaurs, giant turtles, enormous fish, fierce sharks, and the most dangerous sea monsters of all, the mosasaur.

This computer generated animation (CGA) adventure will take you to paleontological digs around the globe, introduce you to the scientists working as detectives to uncover the secrets of this ancient and mysterious ocean world, and under the surface to meet an incredible cast of characters. National Geographic's trademark authenticity combines with innovative imagery, powerful storytelling, and the Market Hall's immersive dome to create a truly unforgettable experience for all the family. Suitable for all ages – Children under 16 must be accompanied by a responsible adult.
