FOSSIL BATS OF THE AMERICAS late Oligocene, Arikareean NALMA The
Brooksville 2 site was discovered in 1994 in a limestone quarry
about 10 km northeast of Brooksville in Hernando County in
central Florida. The site consists of clays and sands filling
karst solution features in marine Oligocene limestone. The
fossils were collected mostly by screenwashing because of the
abundance of microvertebrates and the rarity of larger mammals
(Hayes 2000). The vertebrate fauna includes frogs, lizards,
snakes, and a diverse sample of mammals. Hayes (2000) studied
the Brooksville marsupials, insectivores, lagomorphs, rodents,
and carnivores. Mammals of medium to large body size include:
the horse (Miohippus), two small artiodactyls (Nanotragulus and
the camelid Nothokemas), and six species of small carnivores
(three mustelids and three canids). Besides bats, the small
mammal fauna consists of a didelphid marsupial (Herpetotherium),
two insectivores (the erinaceid Parvericius and Centetodon), one
lagomorph (Megalagus), and a
