New species of ostracodes from the Silica Formation (Middle Devonian) in northwestern Ohio
The Silica Formation of northwestern Ohio contains an abundant and diverse Ostracode fauna. This fauna was previously studied by Grace A. Stewart in 1936, at which time only the lower part of the formation was exposed. This study shows that the fauna is even more diverse than that described by Stewart. Five new species, Hollinella attenuata, Halliella simplex, Nodella tetralobata, N. digitalis, and Primitiella multicostata, are described.
