Sea Monsters

Sea Monsters: A Prehistoric Adventure is a large-format planetarium film shown at the University of Michigan Museum of Natural History's Planetarium & Dome Theater in Ann Arbor, Michigan. Produced by the University of Michigan, the film follows a young Dolichorhynchops ('dolly') through the Cretaceous seas, encountering plesiosaurs, giant turtles, enormous fish, sharks, and the apex predator Mosasaur. The state-of-the-art dome theater transports visitors through prehistoric oceans and the night sky. Tickets are $8, sold at the Museum Store on the day of the show (no online sales). This is a recurring museum education program presented by the U-M Museum of Natural History, not a trade exhibition. Last confirmed public showings at this listing were in spring 2026; future dates are announced by the museum on its events calendar.
