Beyond the game
The real Castoroides
It was a giant beaver, about the size of a bear. Two species are recognized, with records covering different regions of North America.
It was one of the largest beavers ever to live. Its two species occur in different parts of North America, so those finds represent separate histories rather than a single population.
This grouping describes evolutionary relationships. Its members share ancestors; they do not form a chain in which one must turn into another.
