Fig. 5. Thin sections from the Janczyce section. A. Laminated marly limestone (MWG ZI//36/296); sampled below the cephalopod limestone log. B. Cephalopod wackestone (MWG ZI//36/301); Bed 1. Note the presence of goniatitids (g), orthoconic nautiloids (n), gastropods (ga), entomozoacean ostracodes (e) and poor sorting of bioclasts. C. Cephalopod wackestone (MWG ZI//36/303); Bed 3. Note the presence of goniatitids (g), juvenile goniatitids (jg), crinoids (c) and molluscan shell debris. D. Cephalopod packstone (MWG ZI//36/305); Bed 5. Note the presence of juvenile goniatitids (jg), benthic ostracode (o). Note also the best sorting of bioclasts in this bed. Scale bars 2 mm.
