Reconstruction (after Pia 1920) of A ctinoporella podolica Alth. From top to bottom (i) vertical section (2) decalcified portion with anterior branches removed (3) decalcified portion with all branches in position (4) branches with calcareous coating in position (5) calcareous skeleton alone. X40 approx. Remarks. This species, mostly Upper Jurassic in Europe, appears to be Lower Cretaceous in its Middle East occurrences. Pia, dealing with the Podolian type material, relegated A. giimbeli to the synonymy of A. podolica, regarding the differences as not significant. Carozzi referred his Swiss material to A. podolica likewise. This practice is now followed with the Middle East material. This latter suggests smaller verticils and possibly a lower average number of rays than in the.
