AbstractSamples from the Upper Frasnian (Devonian) of Lompret Quarry and Nismes railway section in Dinant Synclinorium, southern Belgium, yielded several chondrichthyan teeth and scales. The teeth belong to three genera: Phoebodus, Cladodoides and Protacrodus. The comparison with selected Late Frasnian chondrichthyan assemblages from the seas between Laurussia and Gondwana revealed substantial local differences of taxonomic composition due to palaeoenvironmental conditions, such as depth, distance to submarine platforms, oxygenation of water, and possibly also temperature. The assemblage from Belgium, with its high frequency of phoebodonts, is the most similar to that from the Ryauzyak section, South Urals, Russia, and the Horse Spring section, Canning Basin, Australia.
Summary(Plain Language Summary, not published)
Samples from the Upper Devonian of two outcrops in southern Belgium, yielded several fossil fish teeth and scales. The teeth belong to three genera: Phoebodus, Cladodoides and Protacrodus. The comparison of the find with selected fish remains from other areas revealed substantial local differences of taxonomic composition that might be linked to differences in water depth, distance to submarine platforms, oxygenation of water, and possibly also temperature of the seawater. The assemblage from Belgium, with its high frequency of a group of fish called phoebodonts, is the most similar to that from the South Urals.
