New reticulated and annulated cephalopods from the Ordovician of the Prague Basin (Central Bohemia)

Popis výsledku v původním jazyce

This work expands the knowledge on the diversity of Ordovician cephalopod assemblages of peri-Gondwana by describing 16 straight-shelled, annulated and/or reticulately ornamented specimens from the late Darriwilian and late Katian strata of the Prague Basin (Central Bohemia). Preservation facilitated the micro-CT investigation of internal shell structures in one of the specimens; in other specimens, the siphuncle and septa are not preserved, and these specimens are thus left in open nomenclature. In total, six species are recognized with one new species established: Anthoceras? sp. A, Anthoceras? sp. B, Sactorthoceras pustulatum new species, Dawsonoceras? sp. indet., Kionoceras? sp. indet., and Palaeodawsonocerina obscurum new combination. In addition, the holotype of Orthoceras evictum was examined and re-interpreted as a conulariid rather than a cephalopod. Paleogeographically, these taxa indicate mixed Baltican, Avalonian and peri-Gondwanan affinities for the late Darriwilian and late Katian cephalopod assemblages.
