Dinobot Island

Dinobot Island is the name given by Spike Witwicky to an island on Earth that can only be accessed by flying through a mysterious energy column floating over the ocean. It is primordial, populated by dinosaurs, and rich in volcanic energy.

The island's position in time is unclear: It may be somehow trapped in a temporal bubble, isolated from the timestream; or the energy column may be a gateway to the entire prehistoric world, with the island being simply the nearest bit of land. Most evidence points to the former theory, but altering the island will produce strange temporal effects elsewhere in the present.
