Type Species
Ksiazkiewiczia lanckoronensis Morycowa, 1976: 80; Original Designation Morycowa, 1976: 80
Type Specimen: Holotype; UJ 4 P 1; Verified; Unknown
Type Locality: Lower Aptian of Poland.
The holotype of the type species is housed at UJ (Krakow) under 4P 1.
Classification
Diagnosis
Colonial, plocoid. Gemmation extracalicinal. Costosepta compact, thick, formed by simple and compound trabeculae, nonconfluent to subconfluent, arranged radially, dentate marginally, spinose laterally. Columella absent. Endothecal dissepiments abundant, vesicular peripherally, mainly subhorizontal and large axially. Exothecal dissepiments subhorizontal. Wall parathecal to septothecal.
Remarks
Morycowa (1976) placed this genus incertae. On the basis of the presence of a parathecal (to septothecal) wall, both simple and compound trabeculae, a dentate type of septal ornamentation, and an extracalicinal budding mode, the genus is placed in the family Faviidae. Reyeros Navarro (1963) described specimens from the Aptian of Mexico which she assigned to the genus Procyathophora Weissermel, 1928. However, in having thick, compact costosepta, which are spinose laterally, they rather correspond the genus Ksiazkiewiczia Morycowa (Procyathophora lacks costae).
