Short summary
Ultrastructures of Lithothamnion corallioides, a crustose coralline alga collected from the Atlantic and Mediterranean Sea at different depths, show high-Mg-calcite cell walls formed by crystals with a specific shape and orientation that are unaffected by different environmental conditions of the living sites. This suggests that the biomineralization process is biologically controlled in coralline algae and can have interesting applications in paleontology.
