New observations on Permocalculus gosaviensis SCHLAGINTWEIT, 1991 (calcareous alga) from the Upper Cretaceous of the Northern Calcareous Alps (Gosau Group, Austria)

Summary: | New thin-sections from the Upper Cretaceous Gosau Group of Brandenberg, Tyrol, Austria, yielded well-preserved specimens of the calcareous alga Permocalculus gosaviensis Schlagintweit. Microfacies are foraminiferal-algal wackestones; stratigraphy is Upper Turonian (?Lower Coniacian). It is shown that the original description was based on oblique sections leading to the incorrect assumption of a piriform segment morphology. Instead, P. gosaviensis is a representative of Permocalculus of the group with constrictions/swellings along the segments (waxing-and-waning type). Permocalculus nikolapantici Radoičić from the Upper Turonian of Serbia is considered a junior synonym of Permocalculus gosaviensis Schlagintweit.
