Graticula, formerly incorrectly named Craticula, [1] is a genus of Palaeozoic coralline alga. [2] They form the framework of reef rocks in the Silurian of Gotland, from the Högklint, Slite and Halla groups. [3]
The Graticulaceae closely resemble the Cretaceous Solenoporaceae, and are only really differentiated by their stratigraphic position. [2]
Graticula mineralized with calcite. [4][ clarification needed]
