# Sea Monsters: A Prehistoric Adventure

Sea Monsters: A Prehistoric Adventure (also called Sea Monsters) is a 2007 American IMAX 3D documentary film by National Geographic, about prehistoric marine reptiles. It alternates modern-day sequences about the work of scientists studying the animals with computer-animated scenes depicting the prehistoric past.
Sea Monsters was well received by critics. The tie-in video game, however, was panned.

## Plot

Brings to life some of the most bizarre, ferocious and fascinating creatures to ever inhabit the ocean. Combines animation with recreations in a prehistoric adventure. A journey to the bottom of the ancient oceans dramatizes awe-inspiring creatures.

### Prehistory segments

The protagonist of the story is Dolly, a female Dolichorhynchops who travels the Kansas Inland Sea with her family, 80 million years ago during the late Cretaceous period.
They encounter various creatures, including, Tylosaurus, Xiphactinus, Cretoxyrhina, and Ammonites.
Dolly gets attacked by a shark (Squalicorax) after her mother was killed by another shark (Cretoxyrhina). Dolly survives due to a passing Tylosaurus killing the shark, albeit with a tooth embedded in her flipper. Later, Dolly's brother is swallowed whole by a young Tylosaurus, who in turn is killed by a larger member of its kind, leaving Dolly alone. Dolly survives to adulthood and goes on to have young of her very own. After seasons of traveling around the Inland sea, Dolly finally dies peacefully of old age.

## Soundtrack

The film's ambient soundtrack was composed by Richard Evans. David Rhodes and Peter Gabriel performed the end credits song "Different Stories Different Lives". The soundtrack has never been officially released.

## Release

The film was released on October 5, 2007. It was promoted with a line of toys from Wild Republic. It won the "Outstanding Visual Effects in a Special Venue Project" award at the Visual Effects Society Awards 2007.

### Reception

The film earned a 100% "Fresh" rating from 12 positive reviews on Rotten Tomatoes. John Anderson of Variety wrote "the science seems sound and the story is exciting", and found it superior to 3D films that merely use the extra dimension as a gimmick. Matt Seitz of The New York Times was impressed by the digital spectacle. The Seattle Times, Orlando Sentinel and Chicago Tribune were of much the same mind.

## Video game

Sea Monsters: A Prehistoric Adventure was made into a game by DSI Games and published by Zoo Digital Publishing. It was released on the Wii, PlayStation 2, and Nintendo DS on October 25, 2007. Players can control Thalassomedon, Henodus, Temnodontosaurus, Tylosaurus, Dolichorhynchops and Nothosaurus in an open-world setting, with no fixed goal besides collecting all the hidden fossils.
The game received poor reviews across all platforms. Cheat Code Central's Amanda L. Kondolojy found the Wii version of the game conceptually interesting, but marred by poor execution, especially in terms of controls.
