| Abstract: | "Modern Erinaceidae include the familiar hedgehog, Erinaceus europaeus, the archetypical primitive placental mammal in the minds of many biologists. Now restricted to the Old World, the family flourished in North America during the Miocene when three subfamilies were present there. Restricted to North America, the Brachyericinae seem to have originated on that continent. Both North American genera of Amphechinini (new tribe of the Erinaceinae) are well known in the Old World in earlier Oligocene deposits and hence appear to have immigrated into North America just before their first appearance there in the early Miocene. Area of origin of the Erinaceini may be interpreted as (1) unspecified within Holarctica plus the Ethiopian Region or (2) as external to Holarctica, depending on how the evidence is weighed. The sudden appearance of the tribe over the extent of Holarctica plus the Ethiopian Region at the beginning of the Miocene and the existence of an adequate structural ancestor in No... |
