Fish Otoliths from the Middle MIocene of Kienberg at Mikulov, Czech Republic, Vienna Basin: their paleoenvironmental and paleogeographic significance
2007
Sixty-three otolith-based species were recorded in the Kienberg
section, ten of which are new for Central Paratethys (first
fossil record of extant species Scorpaena notata and
Spondyliosoma cantharus). The section provides the richest and
most diverse otolith association of that age for the Vienna
Basin. Actualistic analyses indicates open marine, open
infralitoral sedimentary conditions varying between 30 and 80 m
depth with sandy-muddy/sandy bottom and possibly seagrass beds,
in subtropical climate with gradual upwards cooling. A higher
diversity of gadoids in contrast with the lowest Badenian of
the Central Paratethys documented the decline of the so called
climatic optimum in the Miocene of Middle Europe. The dominance
of Atlantic and Atlantic-Mediterranean taxa indicates an open
communication with theses domains and confirm the idea of the
still functioning transdinaride corridor.
