| Description: | A compound rugose coral from the Lower Carboniferous with a thick columella; central tabulae and marginal dissepiments. It is massive and ceroid, i.e. the walls of adjacent corallites are joined together. British Geological Survey Biostratigraphy Collection number GSE 1366. It is commonly found in shallow water limestones. In life, the soft-bodied animal called a polyp lived in the calcareous skeleton called a corallum. In the rugose corals there was a hollow in the top surface called a calice in which the polyp sat together. The corallum had various tabulae and septa, dissepiments and in the case of Lonsdaleia a central calcareous rod or columnella. Rugose corals are solitary or colonial types with bilateral symmetry.
