Anotace

V originále

In the southern part of the Moravian Karst (NE of Brno, Czech Republic) are well exposed Upper Devonian to Mississippian sequences with excellent sedimentary record through the stage boundaries. The Frasnian/Famennian (Hladil et al. 1991), Famennian/Tournaisian (Kumpan et al. 2013) and Tournaisian/Viseán boundaries (Kalvoda et al. 2010) were determined both biostratigraphically and eventostratigraphically. Preliminary results of the recent biostratigraphic research on the Lower/Middle Tournaisan Substage boundary in the sections Lesní lom, Anaklety and Říčka Valley are presented herein. Joint presence of conodonts and foraminifers gives a good opportunity for precise correlation between the deep to shallow water successions in the Western and Eastern Europe. Ichthyoliths, trilobites, brachiopods and other fauna is also present. Complete succession of the Early Turnaisian conodont zones (from the sulcata up to the hassi Zone) was previously documented above the the well preserved Famennian beds in the Lesní lom Quarry, Brno-Líšeň (Kumpan et al. 2013). Abundant conodonts of the upper part of the hassi and sandbergi Zone and foraminiferal association of the foram. zone Prochernyshinella disputabilis (Kulagina 2013) were studied recently. Abundant conodonts of the quadruplicata Zone were documented 400 m SE to the Bělka Mill in the Říčka Valley together with foraminifers of the top of P. disputabilis or the lower part of P. tchernyshinensis Zone. In the Anaklety sections are Lower to Middle Tournaisian limestones preserved with hiatus above the Upper Famennian (Rutová 2009). Foraminiferal association typical for the Palaeospiroplectammina tchernyshinensis Zone (Poty et al. 2006, Kulagina 2013) were found with conodonts of the M. Tournaisian base (crenulata conodont Zone). Trilobite association described from this level consits of very specific forms [Liobole (Sulcubole) aff. Castroi, Linguaphillipsia cracoviensis, Liobole (Panibole) sp., Piltonia krasensis] which are known from the Moravian Karst for the first time (except Piltonia). Also free small-sized brachiopod valves of the suborder Chonetidina (Rugosochonetes?), Productidina and Spiriferida, lingulids and chondrichthyan ichthyolits (e.g. families Phoebodontidae and Protacrodontidae) are present.
