Rhodolith-forming coralline red algae in the CaCO3 biofactory — A case study from the Serravallian of tropical northeastern Indian Ocean
Non-geniculate coral red algae forming rhodoliths have been recorded in the Long Formation, exposed in four different outcrops on Little Andaman Island (Hut Bay). Non-geniculate corallines are represented by species of Sporolithon Heydrich, 1897, Mesophyllum Lemoine, 1928, Lithothamnion Heydrich, 18...
