| Kazakhstan - Otodus mugodzharicus This catalog contains teeth from an extinct Otodontid shark - Otodus mugodzharicus. The Otodus mugodzharicus is a serrated Otodus and represents a unique evolutional form of this species. During the lower Eocene, the Otodus obliquus disappeared in the Caspian area and serrated forms evolved. The Otodus mugodzharicus is the first transitional form identified, and it exhibits light serrations to a wavy blade appearance covering the lower 2/3 of the crown. The side cusps also begin exhibit appearance of serrations or splitting. These Otodus transformed into the Carcharocles genus and the beginning of the Giant White sharks. This W. Kazakhstan area is the best location for producing ( and studying) fossil shark teeth demonstrating the transformation of Otodus to Carcharocles. The teeth are middle Ysperian in age (approx. 50 mya) from the Tolagaysor Formation (basal NP-12 unit) from Aktologay, W. Kazakhstan. These are exceptional and rare fossil shark teeth from a very unique deposit. A must have item for the serious collector of the Giant White fossil shark teeth. Note - all teeth sizes are slant height unless otherwise noted. Click on photos to enlarge. Catalog updated on April 7, 2002. Sorry currently out of stock.
