Field trips

1.Upper Cretaceous (Turonian), led by Elena Jagt-Yazykova and John Jagt ( and
Upper Cretaceous strata in this area are accessible at three (both working and disused) quarries, i.e. Odra, Folwark and Bolko. The Turonian chalks and limestones, with marly intercalations, are locally rich in macrofossils, and the assemblages are closely comparable to those from northern Germany, northern France and southern England, illustrating the Boreal province. Numerous inoceramid bivalves (good index forms), ammonites (small heteromorphs and large-sized desmoceratoids), echinoids, non-inoceramid bivalves, gastropods, sponges, solitary corals and ichnofossils occur. Amongst vertebrates, shark and ray teeth and teleost fish scales and bones are the commonest, but other groups should also be present, albeit rarely.

2.Muschelkalk – led by Adam Bodzioch (
The Upper Silesian Muschelkalk is famous for yielding the richest fossil assemblages across the entire epicontinental Triassic of Europe. The best outcrops are found at numerous active and abandoned quarries located 20-40 km south-east of Opole, where the transgressive-regressive sequence of the Lower Muschelkalk (comprising also the Röth limestones and the Middle Muschelkalk Diplopora dolomites) can be seen. The fossil assemblage is dominated by marine invertebrates, including reef-building scleractinian corals and siliceous sponges. Bones of fish, amphibians and reptiles are rare; however, they do form thin horizons at the Röth/Muschelkalk boundary near Gogolin.
