Fig 16. Virtual thin sections of Marginopora orpheusensis nov. spec. A-form (RGM.1352061).

Fig 16

A) Virtual horizontal section through the lateral chamberlets. B) Virtual horizontal section through the annular passage (ap). C) Virtual horizontal section through the marginoporid structure showing rare annular connections (ac) and the alternating directions of the stolon passage (rs). D) Radial vertical thin section. Arrows indicate the position of A-C and E-G. E) Virtual vertical thin section perpendicular to D showing the straight interseptal ridges in the initial chambers. F) Virtual vertical thin section perpendicular to D showing the increased complexity, especially by increasing the number of disjunctions in the interseptal ridges in the middle chambers. G) Virtual vertical thin section perpendicular to D showing the interseptal pillars in the outer chambers. A-C, E-G Scale bar 100 μm; D: 500 μm.
