The Marne de Flize is a geologic formation in France. It preserves fossils dating back to the Toarcian stage of the Jurassic period.Marne de Flize Formation at Fossilworks.org
Description The finely bedded blue-grey shales contain limestone lenses up to one metre in thickness La Croisette. The Marne de Flize is referred to the early Toarcian (Tenuicostatum and Serpentinum zones according to Mouterde, 1980). It is therefore coeval with the Posidonia Shale of southern Germany.

Vertebrates Reptiles cf. Dorygnathus sp.Buffetaut et al., 2010 Ichthyosauria indet. Fish Osteichthyes indet.
Invertebrates Crustacea indet. Bivalvia indet. Teuthidea indet.
Ammonites Dactylioceras sp. Harpoceras sp.
