The different types of elements that occurred together in conodont apparatuses are not recovered from the fossil record in the expected numbers. The causes of this are complex and difficult to study. Numerous complete articulated skeletons of Ozarkodina excavata (Branson and Mehl) have been recovered from the Eramosa Member at Hepworth, Ontario, and as a consequence, several of the potential bi...

In the late Middle to early Late Jurassic carbonate-clastic Sirogojno Melange in Zlatibor Mountain there is one roughly 35 m thick overturned block with an intact Triassic fore-reefal Dachstein Limestone succession studied for its biostratigraphic age, content and microfacies characteristics. The starts coarse-grained rudstones followed by meter-sized reefal blocks intercalated partly layered r...

Pelagic deep-sea siliceous successions in accretionary complexes preserve precious records of a vast deep seafloor that is now lost due to plate subduction. Microfossils are the key means age assignment these successions, but poor preservation tectonic deformation and metamorphism at subduction zone hamper biostratigraphic records. X-ray computed microtomography, while not widely used studies u...

Accurate palyno-analysis by S. Loboziak (from 1980 to 1983) of 28 samples from the Upper Givetian Middle Frasnian Blacourt, Beaulieu and Ferques Formations 44 Lower Famennian Hydrequent Formation are re-evaluated. Chelinospora concinna, Verrucosisporites bulliferus, Cirratriradites jekhowskyi, Lophozonotriletes media first occurrences major criteria for Frasnian, well calibrated conodonts. Cymb...

frasnian - famennian boundary in the kal-e-sardar section (east of tabas, central iran) is investigated on the basis of conodonts. distribution of thirty-three species and subspecies in the stratigraphic column enables us to recognize a barren interval and five biozones; upper rhenana, upper part of upper rhenana - linguiformis, lower to middle triangularis, upper triangularis, lower crepida. b...
