The present work gives a systematic study and description of Bahariya teetotumensis n. gen. n. sp. of echinoid spatangoids, collected for the first time from the Middle Eocene (Bartonian) Mokattam Formation at the southern confines of Teetotum hill to the east of Qazzun sand dunes, where it characterizes the lower part of Teetotum section in the northeastern plateau of Bahariya Oases. An unconformable hiatus represents a gap in the stratigraphic succession of the Eocene of north Bahariya Oases. The chronostratigraphic equivalent of this missing interval in the northeastern plateau of Bahariya Oases spans the whole Lutetian. The echinoid collected from this locality appears to represent a shore shelf assembladge and indicates that Mokattam Formation was deposited on carbonate platform through the earliest incursion of the epicontinental sea during the late Middle Eocene time. In-between the identified echinoid collection, Bahariya teetotumensis n. gen. n. sp. had been separated, which f
