	Lacustrine depositional systems provide a valuable record of palaeoenvironmental conditions since they rely on a delicate balance between accommodation space and water-sediment supply controlled by tectonic activity and climatic conditions. This study presents new sedimentological and micropalaeontological information from the early\&nbsp;Miocene\&nbsp;lacustrine Oued Tilatou Formation, northeastern Algeria. Based on sedimentary facies and\&nbsp;microfossil\&nbsp;assemblages, the Oued Tilatou Formation (OTF) is divided into two discrete units, the Lower OTF and the Upper OTF. The Lower OTF is characterised by reddish clay-rich carbonate\&nbsp;mudstone\&nbsp;containing reworked foraminifera and\&nbsp;ostracods\&nbsp;interspersed by polymodal clast-supported conglomerates attributed to alluvial deposition. The Lower OTF was deposited under fluvial{\textendash}palustrine conditions, marked by a notable terrigenous sediment influx. In contrast, the Upper OTF encompasses greenish charophyte-dominated (Sphaerochara\&nbsp;sp.) carbonate\&nbsp;mudstone\&nbsp;interbedded with silty carbonate mudstone, and dolomitic wackestone containing charophyte thalli, several ostracod species, and\&nbsp;stromatolites. The dominant ostracod taxa within this interval are\&nbsp;Mediocypris\&nbsp;sp. cf.\&nbsp;M. candonaeformis, indicating freshwater{\textendash}brackish water conditions. The transition in depositional facies from the Lower OTF to the Upper OTF is interpreted as reflecting changes in the environment from fluvial{\textendash}palustrine to shallow water lacustrine with fluctuation in\&nbsp;freshwater input\&nbsp;during the\&nbsp;Burdigalian\&nbsp;(Early Miocene). This study provides new insights on the interplay between early\&nbsp;Miocene\&nbsp;climate conditions and the tectonic uplift of the Aur{\`e}s Massif, and their implications for lacustrine palaeoenvironmental conditions.
