Taxonomy
Eumorphotis was named by Bittner (1901) [Sepkoski's age data: Tr Indu-l Tr Carn Sepkoski's reference number: 94]. It is not extant. Its type is Eumorphotis telleri.
It was reranked as Pseudomonotis (Eumorphotis) by Spath (1935).
It was assigned to Pseudomonotis by Spath (1935); to Etheripectinidae by Newell and Boyd (1995); to Pterioida by Sepkoski (2002); and to Aviculopectinidae by Hayami (1975) and Ros-Franch et al. (2014).
