Abstract: To actualize the available data regarding Cenozoic fi sh materials housed in the vertebrate
fossil collection of the Hungarian Natural History Museum (HNHM), Middle Miocene (Badenian)
chondrichthyan remains, unearthed at St. Margarethen (Burgenland, eastern Austria) are revised in
detail. Among the specimens, a mislabelled, slightly disarticulated, partial dentition surrounded by
associable placoid scales and portions of suggested cartilage, referred to a juvenile individual of an
indeterminate Carchariidae or Odontaspididae has been found. This specimen represents the first
articulated shark fossil ever discovered in the Miocene of the Central Paratethys. The material also includes
a large-sized, pathological tooth of Otodus (Megaselachus) megalodon, which is the largest and
most spectacular of all Otodus (Megaselachus) megalodon teeth of the HNHM collection. The HNHM
collection includes osteichthyan remains, also unearthed at St. Margarethen, but these specimens are
only shortly mentioned. Although the Middle Miocene marine vertebrate fossils of St. Margarethen
are actively investigated for over one and a half centuries, the HNHM material adds new and important
data to our knowledge on the locality’s chondrichthyan fauna. The present paper also highlights
the importance of accurate re-investigation of museum fossil collections. With 112 figures. Keywords: Hungarian Natural History Museum, Middle Miocene, Badenian, Austria, Otodus megalodon, St. Margarethen
