Text-Fig. 24 Pleurocora haueri Milne Edwards & Haime, 1848d , Campanian-Maastrichtian of Antarctica (syntype of Oculina Nordenskjˆldi Felix, 1909, NRZ Cn94), cross view, oblique, polished surface, scale bar: 5 mm (from Filkorn 1994, see full reference in Reference list; copyright 1994 by the American Geophysical Union; reproduced by permission of American Geophysical Union).

Dimensions. d = 5–7 mm, juveniles around 3.5 mm; s=32–48

Description. Subdendroid colony; costosepta developed in 4 incomplete or complete cycles in 6 systems; pali occur in front of oldest cycle, usually fuse with the columella ; columella trabecular, irregularly papillose or made of twisted segments.

Remarks. The systematic position of Oculina Nordenskjöldi Felix has been dicussed for nearly a century. In the original description even Felix himself expressed some doubts about the assignment of the syntypes to the genus Oculina . Filkorn (1994, figs 26 [1–2]) gave the first photographic illustration of the syntypes. He also expressed doubts about the grouping with Oculina . As previously pointed out by Filkorn, characteristics of the species include compact to subcompact septa, development of synapticulothecal (septothecal in places) wall and pali, as well as a trabecular columella which is irregularly papillose or fused, forming twisted segments.. Therefore, the assignment to the genus Pleurocora is suggested.

Type locality of species. Turonian-Campanian of Austria (Gosau Group) .

Distribution. Turonian-Campanian of Austria (Gosau Group), Campanian-Maastrichtian of Antarctica (Seymour Island, Snow Hill Island).
