# List of fossiliferous stratigraphic units in Madagascar

Several fossiliferous stratigraphic units in Madagascar have provided fossils, most notably the Maastrichtian Maevarano Formation and the Jurassic Isalo III Formation. The oldest fossil-bearing formations date to ages before the break-up of Madagascar from Africa and India; the units of the Sakoa Group are found in both India and Madagascar, while the Beaufort Group is shared with southern Africa.
