Mali Alan Pass - Lower Jurassic with Palaeodasycladus

lower Jurassic deposits at Mali Alan pass are extremely fossiliferous with numerous algal remnants, dominated by species and varieties of the genus Palaeodacycladus. The represented taxa are: Palaeodasycladus mediterraneus PIA var. mediterraneus, P. mediterraneus var. heraki (SOKAČ & NIKLER), P. mediterraneus var. illyricus (SOKAČ & NIKLER), P. mediterraneus var calciticus SOKAČ, P. mediterraneus var. elongatulus PRATURLON, Palaeodasycladus dolomiticus (CROS & LEMOINE), P. barrabei LEBOUCHÉ & LEMOINE ex GRANIER & DELOFFRE. This stop is a type locality of species Palaedasycladus anae (SOKAČ), P. multiporus SOKAČ, P. alanensis SOKAČ, and P. benceki SOKAČ. The latter three species and the Eodasycladus ogilviae CROS & LEMOINE are relatively rare in the total fossil content. According to the findings of a significant foraminiferal assemblage, consisting of Lituosepta recoarensis CATI, Planisepta compresa (HOTTINGER), P. termieri (HOTTINGER), Orbitopsella primaeva (HENSON), and O. praecursor (GÜMBEL), in the higher part of the continuous Lower Jurassic column, the stratigraphic position of this locality can be determined as Upper Hettangian– Sinemurian.
