Archaeolithophyllum is a genus of conceptacle-bearing red alga that falls in the coralline stem group. It somewhat resembles Lithophyllum.[1][2]
As of today, Archaeolithophyllum is the only Palaeozoic coralline to bear clear conceptacles,[3] although the earlier Graticula does bear reproductive structures.[4]
It mineralized using aragonite.[3] Its conceptacles are cone-shaped protrusions that extend outwards from the thallus surface and have a single central opening.[5] It probably encrusted muddy or sandy surfaces.[5]
