Short summary
This study explores how climate-driven changes in water balance affected an ancient lake during the Jurassic in Patagonia, and influenced how plant and algal material were deposited and preserved. By combining field observations with palynological analysis, we identified shifts between wetter and drier periods. These shifts controlled lake size, water conditions, and the type and amount of organic matter preserved, improving our understanding of how ancient lake systems record environmental change.
