Rhombopora sp.

Fig. 5L.

Material examined.—Treskelen, sample and two thin sections ZPAL Br. 12/Cr. 44; Hyrnefjellet, samples and two thin sections ZPAL Br. 12/H10 and H34; Gipsvika, thin section PMO 170.911B.

Remarks.—Fragments of Rhombopora occur in many thin sections, but reliable orientations are lacking and rather few measurements could be made. Colonies have diameters ranging between 0.88 and 1.07 mm and exozones widths 0.28 and 0.30 mm. Zooecia in endozone observed in transverse section have a rather square outline. The most similar species is Rhombopora optima Gorjunova, 1975 , from the Artinskian of Pamir, but better material is required for a more conclusive identification.
