ABSTRACT

A single specimen of Aturia alabamensis was found in the lower Yazoo Clay or upper Moody's Branch Marl at Creola Bluff on the Red River at Montgomery, Louisiana. Other reports of the occurrence of this species at various localities in the Gulf Coast region emphasize its absence from equivalent age beds in the Louisiana-Texas area. The scarcity of this pelagic animal in the above lithologic units suggests possible ecologic implications.
