Polyastropsis cf. fascigera ( Felix, 1909)

cf 1909 Isastraea fascigera – Felix: 172, pl. 7, fig. 2.

v 2013 Thalamocaeniopsis sp. – Löser, Werner and Darga: 63, pl. 8, figs 7–9.

Material.

BSPG 1947 XVI 56; two thin sections.

Remarks.

In Löser et al. (2013 c) this specimen was assigned to the genus Thalamocaeniopsis . This is changed here. Thalamocaeniopsis has polygonal corallites and a marked wall, even if thin and incomplete, whereas Polyastreopsis has no wall at all and the corallite outline is irregular. The specimen differs from Polyastropsis fascigera by having smaller distances of the corallites and a higher number of septa.

Other occurrences.

Upper Aptian of the Western Tethys ( Spain), lower Albian of the Western Atlantic ( Mexico), lower Cenomanian of the European Boreal ( Germany).
