Abstract
The late Miocene fauna described here represents
the earliest step in a sequence of late
Tertiary faunas studied as a part of a long
range investigation into the interrelationships
of the factors of faunal change. The study is
deliberately provincial to reduce biogeographic
effects and to allow independent time controls
to be developed through detailed geologic
mapping.
The concept of the bulk fauna is used to
indicate the entire fauna of the Northern Great
Basin at any particular time. The association
or community is the basic unit of study, the
bulk fauna is the whole of which the associations
are the overlapping parts.
