Geocache Description:


le lépidodendron


En paléobotanique, le genre Lepidodendron regroupe des lycopodes arborescentes fossiles, appartenant à l'ordre des Lycopodiales. La répartition stratigraphique s'étend du Dévonien au Carbonifère (-400 à -290 millions d'années)

Les roches où l’on trouve les plantes fossiles de la tranchée des malécots sont des cinérites principalement issues de l’accumulation de cendres volcaniques. Elles proviennent de volcans complètement disparus.
