"Thrinax baumgartneri" is an extinct species of shark. It was classified based on two relatively complete teeth and two isolated crowns. Due to the limited material available and its similarities to "Chlamydoselachus fiedleri", it has been suggested that the criteria with which "T. baumgartneri" is separated from "Chlamydoselachus fiedleri" are within the normal variation of "Chlamydoselachus".
