Abstract

The Bridger Formation in the Green River Basin has been divided into two members, the lower Black's Fork member and the upper Twin Buttes member. 'Ihe Black's Fork member is composed of' biostratigraphlc zones A and Band the Twin Buttes member is com-posed of biostratigraphic zones C, D and E. Recent workers have found that zones A and B contain the same fauna and therefore represent just one biostratigraphic zone (McGrew 1971, Robinson 1970). Future studies of the biostratigraphic zones of the Twin Buttes member are necessary to determine if the C, D and E zones are valid. Some are currently being conducted,
