? Metriophyllum sp.

Fig. 8I .

Material.—Single specimen from the stromatoporoid biostromes of Topluca (Bartın), uppermost Famennian.

Description. —The section has a diameter of 3 mm and there are 16 septa. The latter are thin and fuse together at the centre of the corallum. No septal spine was observed. There is neither fossula nor dissepiments. The wall is thin.

Remarks.—Small solitary undissepimented and columellate rugose corals occur in the Strunian of Germany and Belgium and in equivalent levels in N Poland. They were never described or classified in an accurate way. Chwieduk (2005) classified his specimen as Lophophyllum sp. ; Bless et al. (1998) attributed the corals from W Germany to? Metriophyllum sp. while Denayer et al. (2011) named the corals from Belgium Amygdalophyllum ? sp. This taxon seems to be restricted to stromatoporoid facies of the uppermost Famennian. This specimen is similar to the juvenile stages of corals attributed to? Amygdalophyllum or? Metriophyllum from Belgium and Germany. These taxa are also similar to juvenile stages of the coral figured by Różkowska (1969) under the name Fasciculophyllum dobroljubovae from equivalent levels of the Holy Cross Mountains (S Poland).
