Archaeolithophyllum
Encyclopedia
Archaeolithophyllum is a genus of conceptacle-bearing red alga that falls in the coralline
stem group that somewhat resembles Lithophyllum
; it's the only Palaeozoic coralline to bear clear conceptacles, although the earlier Graticula
does bear reproductive structures.
It mineralized using aragonite. Its conceptacles are cone-shaped protrusions that extend outwards from the thallus surface and have a single central opening. It probably encrusted muddy or sandy surfaces.
Coralline
Coralline means "resembling coral" and may refer to:* Coralline algae, whose fronds are covered with calcareous deposits.* Coralline rock, formed by the death of layers of coralline algae.* Sclerosponges, sometimes called "coralline sponges"....
