The first Early Jurassic ammonite find in central Poland

Journal Title: Volumina Jurassica - Year 2014, Vol 12, Issue 1

Abstract

[i]Tragophylloceras [/i]cf. [i]loscombi [/i](Sowerby) has been found in the Kaszewy 1 borehole (central Poland), in the Upper Pliensbachian strata (Margaritatus Zone, Subnodosus Subzone), assigned to the Drzewica Formation. Hitherto, all ammonite finds in the epicontinental Lower Jurassic in Poland have been restricted to Western Pomerania (NW Poland). This find points to a wider extent of the transgressive event occurring in the late Margaritatus Zone, following widespread regression at the beginning of this zone. Rapid and pronounced sea level changes in the early Late Pliensbachian confirms the hypothesis linking these changes with glacioeustasy.

Radiolarian assemblages from the uppermost Oxfordian (Hypselum Zone) deposits of two sections (Katarowa Góra and Bobrowniki) in the Wieluń Upland (central Poland) are studied for the first time. The overall composition...

Preliminary results of palynological studies of Upper Jurassic flora-bearing deposits from Wólka Bałtowska, NE margin of Góry Świętokrzyskie Mts, Poland

Three sampies of flora-bearing limestone from Wólka Bałtowska were analysed for palynology. They yielded organic-walled dinoflagellate cysts (dinocysts) and sporomorphs, as well as rich phytoclast assemblages including l...
