Baños del Flaco Formation (Chile) |
The Baños del Flaco Formation is a Late Jurassic to Early Cretaceous (Tithonian to Berriasian geologic formation in central Chile. The formation comprises limestones and sandstones deposited in a shallow marine to fluvial environment.[1][2] Fossil ornithopod tracks have been reported from the formation.[3]

Among others, the following fossils have been found in the formation:[4]
- Ichnofossils
- Ammonites, echinoderms and bivalves
