NEW OBSERVATIONS ON PERMOCALCULUS GOSAVIENSIS SCHLAGINTWEIT, 1991 (CALCAREOUS ALGA) FROM THE UPPER CRETACEOUS OF THE NORTHERN CALCAREOUS ALPS (GOSAU GROUP, AUSTRIA). Authors: FELIX SCHLAGINTWEIT. |

Abstract: 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 piryform 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. |
