Text-fig. 3. Stratigraphic section through part of the Ashawq Formation at the Omanitherium type locality, Dhofar Governorate, Oman. Beds A–D are indurated cliff-forming strata identified in the accompanying field photographs (Textfigs 4, 5). Note the increase in marine influence as one ascends through the section, the fauna in Beds A and B being dominated by freshwater molluscs and land snails, with few brackish water specimens, whereas the biota in Bed D is frankly marine with a single specimen of the freshwater snail Pila. Bed C yielded Vermetus, oysters and sponges, but also contains abundant land snails and a low diversity of freshwater gastropods. in Large Mammals From The Rupelian Of Oman - Recent Finds
