Local extinction of sharks of genus Carcharias Rafinesque, 1810 (Elasmobranchii, Odontaspididae) in the eastern Pacific Ocean

Fossil record has shown that the genus Carcharias and probably species C. taurus Rafinesque, 1810 occupied the western coast of South America during the Miocene and part of the Pliocene. The genus is absent in the area today. It is suggested that its local extinction was the consequence of a drop of...
