A preliminary report on the early Oligocene (Rupelian, Kiscellian) selachians from the Kiscell Formation (Buda Mts, Hungary), with the re-discovery of Wilhelm Weiler’s shark teeth

An Early Oligocene (Rupelian, Kiscellian), partially published shark tooth material, unearthed from the Kiscell Clay (Budapest, Hungary) is shortly reviewed here. A few shark taxa have been published by Wilhelm Weiler in 1933 and 1938, and some of this material was re-dis- covered in the Hungarian Natural History Museum. Th e here described shark taxa are Notorynchus primigenius , Hexanchus agassizi , Heptranchias howelli , Araloselachus cuspidatus , Carcharias spp., Carcharoides catticus , Isurolamna gracilis , Otodus ( Carcharocles ) angustidens , Alopias cf. exigua , Car- charhinus sp., and Physogaleus latus . Th e results indicate a relatively diverse shark fauna with mixed ecological needs. Th e revised list of the local selachian taxa suggests that a detailed review of all Kiscell shark material (collected in the last century), placed both in public and private collections, is needed.
