Genuclymenia humboldti (Pusch, 1837) from the P. trachytera  and early L. styriacus Zones at Jabłonna and Kadzielnia in the Holy Cross Mountains.

Genuclymenia humboldti;  growth lines, suture, two stages in development of suture, septal geometry and outline of the shell.

Diagnoza

Umbo covering about one third of the conch diameter; slopes of the flank lobe merging approximately at right angle, the ventral one obliquely crossing the conch flanks.

Porównanie

Probably Ammonites humboldtii Pusch, 1837, based on a pyritized specimen from bituminous calcareous shale exposed at the foot of Kadzielnia hill in Kielce, is the first reference to this species, but Pusch (1837) was uncertain whether the siphuncle is ventral or dorsal. Gomi-monomeroclymenia humboldti genulobata, based on the material from Sieklucki’s brickpit, with pointed flank lobe of the suture seems to fit within the range of the species. The holotype Flexiclymenia puschi collected at Ostrówka from the Prolobites Zone strata seems to representPraeflexiclymenia curvidorsata. Flexiclymenia tempestiva Czarnocki, 1989, F. staszici Czarnocki, 1989 and F. simosa Czarnocki, 1989 are conspecific with G. humboldti.
