Puschastraea kamiennae Roniewicz, 1966: 214, pl. 14, figs 1a - d; Monotypy Roniewicz, 1966: 214
Type Specimen: Holotype; ZPAL H.III/330; Verified; Dry Preserved
Type Locality: Bałtów, Holy Cross Mountains, Poland. Middle- Late Oxfordian, Late Jurassic
Colony astraeoid, with flat upper and lower colony surfaces; intercalicular space depressed; costosepta exsert, subconfluent, fusiform, differentiated into two size orders, distal border denticulated, internal borders with projections which form well develpped papillar columella; lateral sides granular; large dissepiments travers the lumen; peritheca rudimentary, built of elements prolonging from the endotheca. Mode of increase unknown. Microstructure unknown.
Described and illustrated by Roniewicz 1966, with corallite structure presented in thin sections.
In asteroid colony type the genus is similar to Complexastrea d’Orbigny, 1849 and Lyubasha Roniewicz, 2008. From both it differs in having papillar columella and in costosepta differentiated into two size orders only; from the latter, additionally, in lacking tendency to form lonsdaleoid septa.
Only the type species is known. The species origins from above massive coralliferous limestones of the Transversarium zone, and was found in the microonkolitic-onkolitic limestones considered to be of the age at the boundary between the Middle and Late Oxfordian.
- Central Europe; Late Jurassic
