Ophiuroids (Echinodermata) from the Lower Cretaceous of Štramberk, Moravia (Czech Republic)

Popis výsledku v původním jazyce

Extremely rare skeletal remains of brittle stars, originating from Lower Cretaceous deposits in the Štramberk area are described and a preliminary discussion of depositional environments represented by these rocks is added. Several assemblages of dissociated ossicles from the Kopřivnice Formation (upper Valanginian, mostly from the Kotouč and Lower Blücher quarries) comprise only vertebrae. In contrast, an assemblage from the ?Hradiště Formation (Hauterivian and Barremian, Municipal quarry) has yielded taxonomically important lateral arm plates, which have enabled the present study of ophiuroid diversity. A total of five species have been found, including a single new taxon, Ophiotitanos moravica sp. nov. The remaining taxa are left in open nomenclature. Similar to what has been documented from the Cenomanian and Turonian of the Bohemian Cretaceous Basin, representatives of the genus Ophiotitanos predominate in the present assemblages. The presence of Ophiotitanos, euryalids, ophiomusaids and ophiacanthins is reminiscent of some ophiuroid faunas from the Upper Cretaceous of Europe. The assemblage from the Municipal quarry differs markedly from ophiuroid faunas of the Aptian of Cuchía (Spain) and Wizard Way (Texas), but is closely similar to the one from the Barremian of Serre de Bleyton (France). Problems surrounding echinoderm occurrences in the Kopřivnice and ?Hradiště Formations are discussed.n
