The Grès à Voltzia is a geologic formation in France. It preserves fossils dating back to the Triassic period, more specifically the Anisian stage of the Middle Triassic epoch. It represents a lagerstatte that is well known for its palaeoflora, which shares numerous similarities with palaeobotanical assemblages in the Iberian Peninsula.[1]
