Article: Cretaceous and Palaeocene species of the ostracod Hornibrookella from Saudi Arabia
Ali A. F. Al-Furaih
Seven new species of the ostracod genus Hornibrookella are described and illustrated from the uppermost Maastrichtian and Palaeocene of eastern Saudi Arabia: Hornibrookella cyclifossata, H. cyclopea, H. cuspidata, H. divergens, H. episcelis, H. posterisella, and H. quinquecellulosa. They occur at earlier horizons than species of the genus described from Europe and Pakistan. A modification of the Liebau diagram has been adopted for the analysis of the ornament.
