Notes on Miocene Bryozoa from Northwestern Florida

Reginald J. Scolaro


Three species of cheilostome Bryozoa from two Miocene formations in northwestern Florida are described herein. Discoporella umbellatta depressa (Conrad) and Hippoporidra calcarea (Smitt) are reported for the first time from the Red Bay Formation. The occurrence of D. umbellata depressa and Cupuladria biporosa Canu and Bassler represent the first report of Bryozoa from the Yellow River Formation. As these species are broad ecologic indicators, it is thought that the Red Bay and Yellow River formations were deposited in muddy, somewhat turbulent, warm temperate environments and under conditions adverse to the development of a large bryozoan community.
