Fig. 10. Stellaphyllia luciensis gen. et sp. nov. Microstructure. DPO15.444. A. Occurrence of three different organisms in the same ultra−thin section: Stellaphyllia luciensis in transverse stellate section (h,top left),a larger transverse section of striatoporid tabulate coral (t,top right) and a small fragment of fenestellid bryozoan (b,bottom). Note the three different microstructures: extended microlamellae disposed in a large regular curve in Stellaphyllia,short and thick microllamellae arranged on both sides of narrow granular median plates in the tabulate coral,and very thin lamellae with a regular wavy patt ern of the bryozoan; × 220. B. Detail of the microstructure of Stellaphyllia luciensis gen. et sp. nov.: extended,rather thin microlamellae with cupular surface showing the same orientation of the cupules concavity towards growth direction of the skeleton; microlamellae are disposed in regular conformity; colour change in the lower left part corresponds to a change in the orientation of these microelements; × 450. C. Detail of the contact between a bryozoan in the lower part and an auloporid tabulate coral in the upper part. The bryozoan shows a microstructure composed of very thin lamellae lacking a clear cupulosity, disposed in a regular undulating pattern with each peak axed by a spiny trabecular structure. On the other hand,the auloporid tabulate shows a microstructure composed of larger and thicker lamellar elements than the bryozoan; × 450.
