Several studies from around the world suggest the Miocene was a key period in the evolutionary history of diatoms. However, Miocene diatom assemblages from the southwestern Atlantic Ocean are nearly unknown. This study aims to provide a palaeoenvironmental interpretation of the analysed succession. Additionally, to highlight temporal and regional changes, the assemblage is compared with known modern and fossil assemblages from Patagonia and other regions of the world. Finally, we provide a detailed description of the extinct diatom taxa recognised throughout the sedimentary succession. A total of 36 diatom taxa were recognised in the 25 analysed samples. Despite the evidence from sedimentology and macro-palaeontology indicating temporal changes from inner shelf to estuarine environments, the diatom assemblages are dominated by the coastal marine </span><i>Paralia sulcata sensu lato</i><span style=\"color:rgb(31,31,31);\"> throughout the succession. An important freshwater input into the coastal system is interpreted from our results reflecting more humid climatic conditions when compared with modern diatom assemblages from the same location. In addition, four extinct species were recognised: </span><i>Thalassiosira</i><span style=\"color:rgb(31,31,31);\"> cf. </span><i>yabei</i><span style=\"color:rgb(31,31,31);\">, </span><i>Pseudopodosira westii</i><span style=\"color:rgb(31,31,31);\">, </span><i>Rhaphoneis diamantella,</i><span style=\"color:rgb(31,31,31);\"> and </span><i>Lancineis rectilatus</i><span style=\"color:rgb(31,31,31);\">.
