Proteothrinax baumgartneri is an extinct species of shark. It was classified based on two relatively complete teeth and two isolated crowns, described from the Eocene (Lutetian) Weitwies Subformation in Austria.[1] Due to the limited material available and its similarities to , it has been suggested that the criteria with which P. baumgartneri is separated from are within the normal variation of Chlamydoselachus.[2] This would therefore make P. baumgartneri a junior synonym to and, since there is only one identified species within genus Proteothrinax, the whole genus a junior synonym to Chlamydoselachus.
