A small bone assemblage from Qatar is described. The bones were found in a small cave eroded out of marine sediments and the most likely accumulator of the bones was striped hyaena, Hyaena hyaena. Four species of large mammal are represented in the assemblage, striped hyaena, camel, gazelle and the finless porpoise. In addition there were some rodent and bird bones, the origin of which was uncertain. There were 68 identifiable large mammal bones in total, 2 skulls, 6 mandibles, 11 isolated teeth and 23 postcranial elements, together with 26 ear ossicles of the finless porpoise. In addition, 10 indeterminate large mammal bones were collected. The assemblage was identified as a striped hyaena accumulation firstly by the presence of a skull and mandible of this species in the assemblage, and secondly by the nature of the damage and modifications of the bones. The striped hyaena is probably now extinct in Qatar, and one of the bones was dated radiometrically to 580 ± 200 years. This bone showed characteristic signs of desiccation, and it is similar in preservation to the rest of the assemblage. The numbers and sizes of chewing marks are similar to those seen in spotted hyaena assemblages, and particularly when the maximum sizes of marks is taken into account they are distinct from canid chewing marks. The most striking feature of the assemblage is the abundance of finless porpoise skull bones representing at least 13 individuals, and this is taken to indicate that the hyaena was hunting or scavenging along the coast of the Arabian Gulf about 4km from the den site.
