Tacuarembó Formation (Uruguay) |
The Tacuarembó Formation is a Late Jurassic (Kimmeridgian) geologic formation of the eponymous department in northern Uruguay. The fluvial to lacustrine sandstones, siltstones and mudstones preserve ichnofossils, turtles, crocodylomorphs, fish and invertebrates (bivalves and gastropods).
