In the Asmari Formation, which is the most important Oligocene–Miocene carbonate reservoirs in Iran, broad time zonation is generally used based on larger benthic foraminifera (LBF). In this study, the biostratigraphic zonation of the Asmari intra-shelf basin is re- evaluated based on the spatial and temporal distribution of LBF (i.e., different species of Nummulites, Eulepidina, Archaias, Spiroclypeus, Miogypsinoides, Miogypsina, and Borelis) as well as Sr isotope datasets. This research proposes a new zonation to improve time resolution in the Oligocene and explains the effects of environmental factors on some index fossils and the limited range of some key fauna. The newly proposed zonation consists of one biofacies and nine biozones occurring throughout the Rupelian to Burdigalian allowing differentiating Oligo-Miocene stages, and tuning the chronostratigraphic framework of the Oligocene–Miocene deposits. Moreover, based on this new biozonation, regional-scale palaeogeographical maps of the Asmari intra-shelf basin during Rupelian-Burdigalian were officially established.</div>","PeriodicalId":45442,"journal":{"name":"REVUE DE MICROPALEONTOLOGIE","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.revmic.2020.100408","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114536241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More than 60 species of LBF are currently described from the Indo-Pacific Ocean with the Philippines being recently identified as their potential center of maximum species richness.The Palawan archipelago, also known as the “last ecological frontier” of the Philippines and a hotspot of biodiversity, attracts a growing number of tourists due to its comparatively intact marine environments and picturesque landscapes. Here, we document and illustrate the species-rich fauna of modern LBF from shallow nearshore habitats in northern Palawan. Sampling covered the northernmost part of Palawan's South China and Sulu Sea coasts including the Calamian Islands group. A total of 24 samples were taken from fore-reef slopes, inter-reef areas, a back-reef, seagrass leaves with a nearby mangrove swamp, and a WW2 shipwreck at depths between 0 to 25 <!-->m. We recorded a total of 44 LBF morphospecies, a number that is among the highest reported so far. Heterostegina depressa and Calcarina mayori were identified as the most widely distributed taxa in the study area. We further describe Peneroplis hoheneggeri nov. sp. as a new species of Peneroplis de Montfort. The newly described peneroplid is characterized by single rows of large pits and was previously also documented from Micronesia. Our survey supports the designation of northern Palawan as an exceptionally biodiverse ecoregion with high priority for marine conservation efforts.</div>","PeriodicalId":45442,"journal":{"name":"REVUE DE MICROPALEONTOLOGIE","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.revmic.2019.100387","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109226508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
