Autekologia

Występowanie geograficzne

Mójcza, Międzygórz, and Zalesie in the Holy Cross Mts.

Zasięg czasowy

The lower boundary of the occurrence is difficult to trace because of the rarity
and poor preservation of the elements; probably appears 1.2 m above the bentonite (A. tvaerensis Zone) but typical forms occur much higher in the marly limestones of the Zalesie Formation (A. ordovicicus Zone) .
