Fig. 9. A in Lower Devonian (Emsian) rugose corals from the Cantabrian Mountains, northern Spain

Fig. 9. A. Cantabriastraea cantabrica gen. et sp. nov., specimen DPO 14789. A1. Cross section of tabularium and inner dissepimentarium. Trabeculae are oriented perpendicular to the rows of dissepiments; × 15. A2. Detail of A1; trabeculae intercalate between existing ones or bifurcate; × 20. A3. Septa in cross section with strong dilations in inner dissepimentarium caused by thickening of trabeculae. Towards the periphery (left side) septa become irregular carinate and may split into discrete trabeculae; × 24. B, C. Tabulophyllum bonarense sp. nov. B. Wall of corallite DPO 14673 in cross section. Thickenings of wall and lonsdaleoid dissepiments show a fibrous structure caused by thickened septal bases; × 24. C. Thin septa of corallite DPO 14686 (compare with Fig. 4G) inserting on lonsdaleoid dissepiments (dark lines in lower part of picture). Central part towards the axis (top of picture) is strongly affected by cement; × 24. All specimens from the Upper Emsian of Colle.
