A juvenile Trachinus minutus (Pisces, Perciformes, Trachinidae) from the Middle Oligocene of Litenčice (Moravia, Czech Republic)
2009
Abstract
The paper presents information about the first find of Trachinus minutus (Jonet, 1958) in the Šitbořice Beds (Middle Oligocene) in the Czech Republic. The exemplar is relatively well ossified, however the total length is only 16.5mm.
A comparison of preserved morphologic and meristic characters with features in exemplars from other Europian localities shows its similarity to the specimens from Poland. Slightly different praeoperculare morphology is probably caused by ontogeny.
The taphonomic information is combined with information about finds of terrestrial elements in Menilitic shale and selected bathymetric and paleoecological data are discussed as possible evidences of coastal upwelling.
