Class Echinoidea Leske, 1778

Remarks.—Sea urchin plates, spines and other ossicles are most common in our material. As the Cassian Formation contains the largest and most important Triassic echinoid fauna worldwide (cf. Kroh 2011), it is not suprising that even very rare or unexpected forms, hitherto unknown as articulated findings, can be found.
