| Early
Tertiary Rodents of the Holarctic: Evolutionary and Distributional
Patterns
The origin and
Paleogene radiations of rodents in the Holarctic are the focus of
research projects and field studies which are currently being conducted
in North America and Asia. The fossil records of rodents in the
Eocene show a very interesting geographic distribution between North
America and Asia. The North American Eocene was dominated by paramyidsciuravid
rodents and their derivatives, while the Asian Eocene was dominated
by ctenodactyloid rodents.
