Kurzfassung
Für die Orientierung in den Tiefen der Ozeane entwickelten Wale und Delphine im Laufe der Evolution ein spezialisiertes Hörorgan für ein breites akustisches Spektrum. Die innere Anatomie des Felsenbeins (Perioticum), insbesondere die Morphologie der Hörschnecke (Cochlea) hat bei Säugetieren einen signifikanten Einfluss auf das Hörvermögen. Mittels Röntgen- und Neutronentomographie wird die knöcherne oder fossilisierte Cochlea verschiedener fossiler Repräsentanten ausgestorbener Bartenwalgruppen (wie der Cetotheriidae) sowie moderner Furchenwale (Balaenopteridae) und Glattwale untersucht, ebenso die eines Urwals und einiger Landwirbeltiere. Morphologische Veränderungen, die für die Entwicklung des niederfrequenten Hörens verantwortlich sein können, sollen so erfasst werden. Unterschiede in der Cochlea-Morphologie werden anhand morphometrischer Parameter, wie der Anzahl der Windungen, der Länge der Cochlea und des Krümmungsverlaufs des Cochleakanals bestimmt. Insbesondere die Röntgentomographie ermöglicht eine hochauflösende Darstellung des knöchernen Innenohrs.
Abstract
During their evolution whales and dolphins developed a highly specialized hearing organ for orientation in their deep sea territory covering a broad acoustic spectrum. The internal anatomy of the periotic bone, especially the morphology of the cochlea, has a significant influence on the hearing capability of mammals. The bony and fossilized cochleae of several fossil representatives of extinct baleen whales (e. g., Cetotheriidae) and modern rorquals (Balaenopteridae) and right whales, as well as cochleae of an archaeocete and some land mammals are investigated by X-ray and neutron tomography in order to record morphological changes that may be responsible for the development of low frequency hearing. Differences in the cochlear morphology have been determined by means of morphometric parameters, such as the number of turns, the length of the cochlea, and the curvature of the cochlear canal. In particular, X-ray tomography enables a high resolution display of the bony inner ear.
