Article: Palaeoberesellids (dasycladaceans) from the Upper Jurassic Arab-D Reservoir, Saudi Arabia

Palaeoberesellids, tubular septate dasycladacean algae hitherto only described from the Upper Palaeozoic, have been discovered in the Late Jurassic Arab-D Reservoir from the Khurais Oilfield, Saudi Arabia. Material is referred to a new species, Kamaena khumisensis. Specimens occur in the wackestones and packstones of the lower part of the reservoir, deposited in offshore shelf environments deeper than those containing most of the other described Arab Reservoir dasycladaceans.
