Carcharocles aksuaticus (Menner, 1928)

Otodus aksuaticus[1] is an extinct species of large shark in the family Otodontidae which was once thought to represent a transitional species between the genus Otodus and the genus Carcharocles, but the 2016 analysis shows that Carcharocles should be part of Otodus.[1] They are similar in overall morphology to Otodus obliquus except they have serrations on their cusps and blade. It is sometimes placed in the genus Otodus. It is mainly found in the Ypresian stage of the Eocene epoch. They have been found in the Woodstock Member of the Nanjemoy Formation of Maryland and Virginia and Ypresian sediments in Aktulagay, Kazakhstan as well as the Ypres clay in Belgium and the London Clay in the United Kingdom.[2]
