Material. —Sample Rö37: stubs Rö37_1 (one specimen), Rö37_3 (eight specimens); sample Rö38: stub Rö38_1 (seven specimens); sample Rö416: stubs Rö416_1 (15 specimens), Rö416_7 (seven specimens); sample Rö417: stub Rö417 (15 specimens), Mount Rettenstein , Northern Calcareous Alps, Austria, Lower Pliensbachian .

Remarks.—In Gorgansium gongyloideum we group morphotypes with a spherical cortical shell, a relatively large number of small pores and three spines that are approximately as long as the diameter of the shell. One spine is somewhat longer than the other two. Species with the longer spine almost twice the length of the shorter spines are assigned to Gorgansium alpinum Kozur and Mostler, 1990 .

Stratigraphic and geographic range.—Hettangian to Toarcian (as published, see synonymy list). Worldwide.
