Abstract
This paper presents descriptions of five species of sharks of the families Hexanchidae and Crassodontidanidae from the Cretaceous deposits of South-West Crimea: Crassodontidanus aff. wiedenrothi (Thies, 1983) (Bolshoy Kermen Mountain, lower Hauterivian), Pachyhexanchus pockrandti (Ward et Thies, 1987) (Bolshoy Kermen Mountain, lower Hauterivian), Notidanodon aff. lanceolatus (Woodward, 1886) (Belaya Mountain, lower – middle Cenomanian), N. cf. lanceolatus (near Maryino Village, middle Aptian), and N. dentatus (Woodward, 1886) (Kremennaya Mountain, lower Cenomanian). The tooth of Crassodontidanus aff. wiedenrothi is close in morphology to those of C. wiedenrothi from the Jurassic of Germany. Pachyhexanchus pockrandti is the second record of this species in the Tethys region. Representatives of Notidanodon aff. lanceolatus are sharply different from other species of this genus in tooth morphology; this taxon is, likely, an ancestral form for the family Heptranchidae.
