The family 'Castoridae' contains the two living species of
beaver and their
fossil relatives. This was once a highly diverse group of
rodents, but is now restricted to a single genus, ''
Castor''.
Taxonomy
McKenna and Bell (1997) divided Castoridae into two subfamilies,
Castoroidinae and
Castorinae. More recent studies (Korth, 2002; Rybczynski, 2007) have recognized additional subfamilies of basal castorids, and the following taxonomy is based on these two works.
