Craticula, formerly incorrectly named Graticula,[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]
