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

CS8 Native and non-native Oyster cultivation - Ecosystem service valuation in Brazil 2023

This dataset relies on data collect from D6.2, Agricultural Research and Rural Extension Company of Santa Catarina State (EPAGRI) and available literature. The purpose is to monetarily valuate the ecosystem services and disservices generated by oyster aquaculture in Southern Brazil. Data is presented in terms of productivity (t/year), nutrient retention and emission (kg/t) and economic value (€/year).
