BACKGROUND Paleomicrobiology is a special branch of micropaleontology concerned with the study of bacterial fossils. We have used the term 'oral paleomicrobiology', as in this review we have focused on the ancient oral microflora. Recently, dental calculus and dental pulp have been identified as rich sources of ancient microbial DNA. Study of this ancient genetic material opens a new door to th...

Abstract Orthophragmines are a group of discoidal, lenticular or stellate ‘orbitoidal’ larger benthic foraminifera that thrived in shallow-marine environments low-to-middle latitudes during the late Paleocene and Eocene. They consist two phylogenetically independent families with similar morphology, such as Discocyclinidae (with Tethyan genera— Discocyclina Nemkovella ) Orbitoclypeidae three Or...

In recent years, coastal areas have been threatened by many potential hazards due to global warming, glacier melting and sea level rise. Understanding their evolutionary history development trends can help predict disasters further reduce the corresponding losses. The Hanjiang River delta in southeastern part of China is second largest Guangdong Province has such challenges. Studying sedimentar...

The Qom Formation, a series of shales, sandstones and carbonate deposits, is the last transgression of the sea in Central Iran sedimentary basin. Foraminifera are one of the most important and numerous fossil groups present in the Qom Formation. In this study, the micropaleontology of the Qom Formation in three measured stratigraphic sections in south and west of Tafresh (Rakin, Band-e-Ali Nagh...

New insights into the geodynamic evolution, paleogeographic framework and paleoclimatic setting of Upper Eocene-Oligocene lacustrine basins from South-East France have been provided by an integrative approach combining geochronology, micropaleontology stable isotope analyses. UPb dating on calcite, pollen-based climatostratigraphy strontium sulfur signatures sulfates a robust chronostratigraphi...

In geosciences, micropaleontology studies the evolution of microfossils (e.g., foraminifera) throughout geological records and utilizes such information to reconstruct past environmental climatic conditions. This field depends primarily on visual recognition various features in which makes it ideal apply computer vision technology, specifically deep convolutional neural networks (CNNs), automat...

The formation and dissolution of salt giants impacts ocean chemistry on thousand-million year timescales. Gypsum precipitation weathering changes the oceanic calcium concentration with implications for carbon cycle global temperatures. However, connectivity is necessarily restricted, making timing Ca2+ extraction return more uncertain. Here we reconstruct final phase gypsum Late Miocene Mediter...
