Qualifie les êtres vivants actuels qu'on trouve déjà fossilisés dans les couches sédimentaires très anciennes (primaires notamment) et pour lesquels on constate que les caractères anatomiques et physiologiques n'ont pas subi de changements notables pendant toute la durée des temps géologiques, ce qui les fait parfois qualifier de «fossiles vivants».
