Beyond the game
The real Shonisaurus
It was an ichthyosaur of exceptional size. The numerous incomplete specimens from Nevada come from ancient marine deposits.
Nevada’s Luning Formation contains remains of many individuals, though their skeletons are incomplete. These ancient marine deposits tell the story of a place that once lay underwater, despite its rocky landscape today.
This grouping describes evolutionary relationships. Its members share ancestors; they do not form a chain in which one must turn into another.
