Genus Triploporella Steinmann 1880

? Triploporella sp.

Fig. 14 j-k

Illustrated by a partial section through a thallus showing the primary laterals, hosting a large number of sparitic corpuscles with round sections, probably representing reproductive cysts. The assignment to Triploporella is doubtful, partly because of the lack of secondary laterals, and also because the cysts are more likely simple and not cyst-containers – as they are in Triploporella (sensu Barattolo, 1980) .

Thaumatoporellales

Genus Thaumatoporella Pia, 1927

Thaumatoporella parvovesiculifera ( Raineri, 1922) Pia, 1927

Fig. 14 o, p

Well-known species related mostly to reefal facies, associated with bacinellid structures.

Bryopsidales

Udoteaceae

Genus Arabicodium Elliott, 1957

Arabicodium sp.

Fig. 15 a-c

Rare specimens identified in the Kimmeridgian-Tithonian limestones of the Ay-Petri massif.
