 Drepanodus santacrucensis Dzik, 1994 from the Mójcza Limestone. Diagnoza All mature elements with smooth, very flat cusps expanding on both sides into sharp thin cristae. Porównanie The most characteristic feature for the species is very flat M elements, unlike those of related species. Although the number of collected specimens is limited and their preservation not good, as a result of the unusual fragility of these thin cristate elements, it seems that the apparatus structure was closely similar to that of its probable ancestor D. arcuatus. Their S2-4 elements are hardly distinguishable. Autekologia Występowanie geograficzne Zasięg czasowy Rare specimens of the species occur from 1.3 m below (E. lindstroemi Subzone)up to 1.9 m above the bentonite (A. tvaerensis/superbus transition zone).
